Software Bill of Materials (SBOM)

A Software Bill of Materials (SBOM) represents a comprehensive, structured inventory of all components, libraries, and dependencies that constitute a software application. For DevSecOps leaders and security directors managing complex software development lifecycles, the Software Bill of Materials has become an indispensable tool for maintaining visibility into what's actually running in production environments. Think of an SBOM as the ingredient list for your software - just as food manufacturers must disclose what goes into their products, software organizations now face increasing pressure to document every component that makes up their applications.

The concept isn't entirely new, but the urgency around SBOMs has accelerated dramatically over the past few years. With supply chain attacks becoming more sophisticated and regulatory requirements tightening, organizations can no longer afford to operate with blind spots in their software composition. The Software Bill of Materials provides crucial visibility, enabling security teams to quickly identify vulnerable components, assess risk exposure, and respond to emerging threats before they are exploited.

‍

What is a Software Bill of Materials (SBOM)?

At its core, a Software Bill of Materials is a formal record that contains detailed information about the components, libraries, and dependencies that make up a software product. It includes information such as version numbers and licenses of each component. SBOM tools have emerged as essential components in modern development workflows, helping teams track and secure the complex web of dependencies that make up modern applications. But what exactly is an SBOM, why does it matter, and how can you effectively implement it in your development process?

As we indicated, a Software Bill of Materials (SBOM) is essentially an inventory or "ingredient list" for your software. Just as food products list ingredients so consumers know what they're eating, an SBOM documents all components that make up a software application, including:

• Open source components
• Third-party libraries
• Custom code
• Software frameworks
• Runtime dependencies

Each component in an SBOM is documented with critical metadata such as:

• Component name: The official identifier for the software component
• Version information: Specific version numbers to track exactly what's deployed
• Supplier details: Information about who created or maintains the component
• Dependency relationships: How components relate to and depend on each other
• Licensing information: The terms under which each component can be used
• Package URLs (PURLs): Standardized identifiers for software packages
• Cryptographic hashes: Verification that components haven't been tampered with

The structured nature of SBOMs makes them machine-readable, enabling automated tools to quickly identify security vulnerabilities, license compliance issues, and outdated components. This automation is what makes SBOMs practical for organizations managing dozens or hundreds of applications simultaneously.

The concept isn't new—manufacturing industries have used bill of materials documents for decades. But as software has grown increasingly complex, with applications routinely incorporating hundreds or thousands of components, SBOMs have become essential for understanding what actually resides in your code.

‍

SBOM Formats and Standards

The Software Bill of Materials isn't just a loose concept - several standardized formats have emerged to ensure consistency and interoperability across different tools and platforms. The three most widely adopted SBOM formats are:

• SPDX (Software Package Data Exchange): Developed by the Linux Foundation, SPDX was originally created to standardize how license information is shared. Over time, it evolved into a comprehensive SBOM format that captures security, licensing, and component information. SPDX has become an ISO standard, making it particularly attractive for organizations operating in regulated industries or international markets.
• ‍CycloneDX: Created by OWASP, CycloneDX was purpose-built for application security use cases. It includes rich support for vulnerability tracking, component provenance, and supply chain security metadata. Many security scanning tools favor CycloneDX because of its strong focus on security-relevant information.
• ‍SWID Tags (Software Identification Tags): An ISO standard primarily used for software asset management, SWID tags uniquely identify and describe software products. While less commonly used for security purposes than SPDX or CycloneDX, SWID tags remain relevant in enterprise asset management contexts.

Each format has its strengths, and many organizations find themselves working with multiple formats depending on their toolchain and requirements. The good news is that conversion tools exist to translate between formats, though some information may be lost in translation depending on the specific metadata captured by each standard.

‍

Where Software Bill of Materials Are Used

The applications of SBOMs extend far beyond simple inventory management. Security teams use SBOMs as a foundational element of their vulnerability management programs, enabling rapid response when new vulnerabilities are disclosed. When a critical vulnerability like Log4Shell is announced, organizations with current SBOMs can quickly determine their exposure across their entire application portfolio in minutes rather than weeks.

Vulnerability Management and Incident Response

SBOMs transform how organizations manage vulnerabilities. Traditional approaches required security teams to manually scan applications or query development teams about which components were in use. This process was slow, error-prone, and often incomplete. With SBOMs, the complete inventory already exists and can be automatically cross-referenced against vulnerability databases.

During security incidents, SBOMs become even more valuable. When responding to a potential supply chain compromise, incident response teams need to quickly determine which applications might be affected. An accurate SBOM allows teams to immediately identify every application using a compromised component, drastically reducing mean time to resolution. This capability has become particularly critical as threat actors increasingly target the software supply chain rather than applications directly.

Compliance and Regulatory Requirements

Regulatory bodies worldwide are recognizing the importance of software transparency. The United States government, through executive orders and agency requirements, now mandates SBOMs for software sold to federal agencies. This requirement has rippled through the software industry, with many commercial organizations adopting SBOM practices even when not strictly required.

Beyond government mandates, industry-specific regulations are beginning to reference SBOMs or the transparency they provide. Financial services organizations must demonstrate control over their technology stack. Healthcare providers must ensure their software meets strict security and privacy requirements. SBOMs provide auditable evidence that organizations understand what's in their software and can demonstrate due diligence in managing security risks.

Third-Party Risk Management

When acquiring software from vendors or integrating third-party components, organizations need assurance about what they're bringing into their environment. SBOMs enable buyers to evaluate vendor software before deployment, checking for known vulnerabilities, outdated components, or licensing issues that might create problems down the road.

This dynamic has shifted the relationship between software buyers and vendors. Mature buyers now request SBOMs as part of their procurement process, and vendors who can readily provide them signal their security maturity. Organizations using supply chain security solutions can automate much of this third-party assessment process, making vendor evaluations faster and more thorough.

‍

Why SBOM Tools Are Becoming Essential

The rise of SBOM tools isn't happening in a vacuum. Several factors are driving their rapid adoption across industries:

Regulatory Requirements

Government agencies worldwide are increasingly mandating SBOMs:

• The U.S. Executive Order 14028 requires SBOMs for vendors selling to federal agencies
• The EU Cyber Resilience Act proposes similar requirements
• Various sector-specific regulations in healthcare, finance, and critical infrastructure now reference SBOMs

Organizations that are held to these mandates are now passing them along to their software vendor suppliers, making compliance a contractual requirement to do business. All of this reflects the growing recognition that software transparency is necessary for national and economic security.

Growing Complexity of Software Supply Chains

Modern applications aren't built from scratch—they're assembled. A typical enterprise application might contain:

• 70-90% third-party code (both commercial and open source)
• Multiple layers of dependencies (dependencies of dependencies)
• Components from dozens or hundreds of different suppliers

Teams simply cannot track all these moving parts manually.

‍

Core Benefits of Implementing SBOM Tools

Organizations implementing SBOM tools as part of their development workflow realize several immediate and long-term benefits:

Enhanced Vulnerability Management

SBOM tools dramatically improve vulnerability management by:

• Providing a comprehensive inventory of all components that need to be monitored
• Enabling rapid identification of affected systems when new vulnerabilities are discovered
• Reducing the "time to patch" critical vulnerabilities
• Eliminating blind spots where unknown components might harbor vulnerabilities

When the next major vulnerability emerges, organizations with mature SBOM practices can answer the critical question—"Are we affected?"—in minutes rather than days or weeks.

Improved License Compliance

Software licenses create legal obligations that can have serious consequences if violated. SBOM tools help teams:

• Identify all licenses in use across the application
• Flag potentially incompatible or problematic licenses
• Ensure compliance with license terms and conditions
• Reduce legal and financial risks associated with license violations

This visibility is particularly important for open source components, which often come with specific license requirements that must be followed.

Better Risk Management

Beyond vulnerabilities and licenses, SBOMs improve overall risk management by providing insights into:

• Component age and maintenance status (identifying abandoned dependencies)
• Supplier diversity (revealing over-reliance on particular vendors)
• Software provenance (understanding where code originated)
• Component quality and security practices

These insights help organizations make more informed decisions about which components to use and which might need replacement.

Streamlined Development Lifecycle

Contrary to the misconception that security slows development, properly implemented SBOM tools actually accelerate development by:

• Reducing late-stage security surprises that cause delays
• Automating component evaluation and approval
• Supporting faster dependency updates
• Enabling better component selection decisions

Teams spend less time fixing security issues and more time building valuable features when they have visibility into their components from the start.

How to Create and Maintain a Comprehensive Software Bill of Materials

Generating an accurate SBOM requires integrating the right tools into your software development lifecycle. Manual SBOM creation isn't realistic for modern applications given their complexity, so automation is essential. Most organizations generate SBOMs using one or more methods, often combining them based on their specific needs.

SBOM Generation Tools and Techniques

Software Composition Analysis (SCA) tools scan application code and build artifacts to identify open source and third-party components. These tools examine package managers, dependency files, and compiled binaries to construct a complete component inventory. Popular SCA tools can generate SBOMs in standard formats like SPDX or CycloneDX as part of their normal scanning process.

Build-time SBOM generation integrates directly into CI/CD pipelines, creating an SBOM each time an application is built. This approach ensures that SBOMs stay synchronized with the actual application code, capturing changes as they happen rather than through periodic scans. Tools like Syft, Tern, and various commercial offerings can be integrated into build processes to automatically generate SBOMs without requiring manual developer intervention.

Container scanning tools examine container images to catalog the components they contain. Since containerized deployments have become standard practice, these tools play an important role in SBOM generation for cloud-native applications. Container registries increasingly include built-in SBOM generation capabilities, making it easy to obtain an SBOM for any image in your registry.

Integrating SBOM Generation into DevSecOps Workflows

For SBOMs to remain useful, they need to be generated automatically as part of your normal development workflow rather than as a special activity. This means integrating SBOM generation into your CI/CD pipeline so that every build produces both the application artifacts and a corresponding SBOM.

The specific integration points depend on your development toolchain. For applications built with Maven, npm, pip, or other package managers, SBOM generation plugins can be added to the build configuration. For containerized applications, SBOM generation can occur during image build or as a step in your container scanning process. The key is making SBOM generation automatic and non-optional - if developers need to remember to generate SBOMs manually, it simply won't happen consistently.

Modern DevSecOps platforms often include SBOM management capabilities that handle generation, storage, and analysis of SBOMs across your application portfolio. These platforms can track how component usage changes over time, alert security teams when new vulnerabilities affect existing applications, and provide a centralized view of your software supply chain risk.

SBOM Storage and Distribution

Once generated, SBOMs need to be stored somewhere accessible to the teams that need them. Some organizations store SBOMs alongside their application artifacts in artifact repositories. Others maintain dedicated SBOM repositories or databases that support querying and analysis. The storage approach should support both retrieval of specific SBOMs and cross-application queries like "which applications use library X."

For commercial software vendors, distributing SBOMs to customers presents additional considerations. Some vendors include SBOMs as part of their standard product documentation. Others make SBOMs available through customer portals or API endpoints. The distribution mechanism should make it easy for customers to obtain current SBOMs without creating excessive overhead for the vendor.

Comprehensive List of Components in a Software Bill of Materials

A well-constructed SBOM captures multiple layers of information about software components. Understanding what should be included helps organizations evaluate whether their SBOMs provide sufficient detail for security and compliance purposes.

Direct Dependencies and Libraries

These are the components that developers explicitly include in their applications. For a Java application, direct dependencies are the libraries listed in the pom.xml or build.gradle file. For JavaScript applications, they appear in package.json. These components are usually well-known to development teams since they were consciously chosen for inclusion.

Direct dependencies typically represent the most significant components in an application - major frameworks, database connectors, cryptographic libraries, and similar foundational elements. While developers are generally aware of these components, they may not always know their exact version or be aware of vulnerabilities that have been discovered since the component was originally included.

Transitive Dependencies

Transitive dependencies are components that your direct dependencies rely upon. These often represent the majority of components in modern applications and are frequently invisible to developers who didn't explicitly choose to include them. A developer might add one library to their project, unaware that this library itself depends on dozens of others.

Transitive dependencies create significant security challenges. Developers don't actively maintain or update these components, yet vulnerabilities in transitive dependencies can be just as dangerous as vulnerabilities in direct dependencies. SBOMs make these hidden components visible, allowing security teams to assess their risk and take action when needed.

Operating System and System Libraries

Applications don't exist in isolation - they run on operating systems and rely on system-level libraries. For containerized applications, this includes everything in the base image. For traditional deployments, it includes the OS components that the application interacts with. These system-level components often contain vulnerabilities that can be exploited to compromise applications.

Comprehensive SBOMs include information about these system-level components. For containers, this means cataloging the contents of the base image, including the Linux distribution, shell utilities, and system libraries. This level of detail allows security teams to detect vulnerabilities in base images and take appropriate action, such as rebuilding containers with patched base images.

Proprietary and Internal Components

Not everything in an application comes from external sources. Organizations develop their own internal libraries and components that are shared across multiple applications. These proprietary components should also be tracked in SBOMs, particularly when they're shared across teams or applications.

Tracking internal components provides several benefits. When security issues are discovered in internal code, teams can quickly identify all applications that are affected. It also prevents duplicate effort, as developers can discover existing internal components that meet their needs rather than building new ones from scratch.

Firmware and Embedded Software

For hardware products with embedded software or firmware, SBOMs should capture the software components running on the device. This is particularly relevant for IoT devices, network equipment, and medical devices. Firmware often includes open source components that may contain vulnerabilities, but the embedded nature of firmware can make these components difficult to identify without proper documentation.

‍

SBOM Adoption Challenges and Best Practices

Despite their clear benefits, implementing SBOM practices across an organization presents real challenges. Understanding these challenges and how successful organizations address them can smooth your own SBOM adoption journey.

Tooling and Process Integration

One of the primary challenges is selecting and integrating the right tools for SBOM generation and management. The market offers numerous options, from open source utilities to comprehensive commercial platforms. Different tools excel at different aspects of SBOM management - some focus on accuracy of component detection, others on integration with vulnerability databases, and still others on compliance reporting.

Organizations typically find success by starting with one application or team as a pilot program. This allows them to work through tooling and process issues on a manageable scale before rolling out SBOM practices more broadly. The pilot also helps identify which SBOM format works best for your specific use cases and toolchain.

Organizational Change Management

SBOMs require coordination across multiple teams - development, security, operations, and sometimes procurement and legal. Each team has different priorities and concerns, and successful SBOM programs need buy-in from all stakeholders. Developers may view SBOM generation as additional overhead unless they understand the security benefits. Security teams may lack visibility into development workflows and need education about where SBOM generation should fit.

Clear communication about why SBOMs matter helps overcome resistance. When developers understand that SBOMs enable faster vulnerability response and reduce the chances of being paged at 2 AM for security incidents, they become more supportive. When business leaders understand that SBOMs are increasingly required by customers and regulators, they're more willing to invest in the necessary tools and processes.

SBOM Quality and Completeness

Not all SBOMs are created equal. An SBOM that only captures direct dependencies while missing transitive dependencies provides incomplete visibility. An SBOM that lacks version information for components can't be effectively used for vulnerability management. Organizations need to establish quality criteria for their SBOMs and implement validation processes to ensure generated SBOMs meet those criteria.

SBOM quality depends heavily on the tools used for generation and the specific application characteristics. Applications that follow standard package management practices generally produce more accurate SBOMs than applications with custom build processes or vendored dependencies. Identifying applications that produce low-quality SBOMs allows teams to focus improvement efforts where they're most needed.

Keeping SBOMs Current

Software changes constantly, and SBOMs need to stay synchronized with those changes. An SBOM that accurately reflected your application six months ago may be dangerously outdated today if dependencies have been added, removed, or updated. Automated SBOM generation as part of your build process solves this problem by ensuring that every new version of an application comes with a corresponding updated SBOM.

For purchased software, staying current is more challenging since you depend on vendors to provide updated SBOMs when they release new versions. Part of vendor management should include expectations around SBOM updates and mechanisms for obtaining current SBOMs without excessive friction.

‍

The Business Value of Software Bill of Materials

Beyond the technical security benefits, SBOMs deliver measurable business value that resonates with executive leadership. Understanding these business benefits helps security teams make the case for SBOM investments.

Risk Reduction and Cyber Insurance

Cyber insurance carriers are becoming more sophisticated in their underwriting processes, asking detailed questions about security practices. Organizations that can demonstrate comprehensive visibility into their software supply chain through SBOMs may qualify for better coverage terms or lower premiums. More importantly, SBOMs reduce the actual risk of costly security incidents by enabling faster vulnerability remediation.

When security incidents do occur, having current SBOMs dramatically reduces the cost and duration of incident response. Teams can quickly scope the impact rather than spending days or weeks investigating which systems might be affected. This rapid response capability can mean the difference between a minor incident and a major breach.

Competitive Advantage in Sales

For software vendors, the ability to provide high-quality SBOMs to customers has become a competitive differentiator. Enterprise buyers increasingly require SBOMs as part of their procurement process, and vendors who can readily provide them have an advantage over those who cannot. This is particularly true in regulated industries and when selling to government agencies.

The SBOM also demonstrates security maturity to potential customers. An organization that maintains detailed SBOMs signals that they take security seriously and have invested in the processes and tools necessary to manage their software supply chain. This perception can be valuable during sales processes where security is a key concern.

Operational Efficiency

While implementing SBOM practices requires upfront investment, the operational efficiencies they enable often justify that investment quickly. Security teams spend less time manually investigating component usage and can respond to vulnerabilities faster. Development teams benefit from better visibility into their dependencies and can make more informed decisions about component selection and updates.

License compliance becomes more manageable with SBOMs since all component licenses are documented in one place. Legal teams can review SBOMs to identify any licensing issues before software ships rather than discovering problems after the fact. This proactive approach prevents costly license compliance issues and reduces legal risk.

‍

Future Trends in Software Bill of Materials

The SBOM landscape continues to evolve rapidly as both technology and regulatory requirements advance. Understanding where things are headed helps organizations prepare and ensures their SBOM practices remain relevant.

Enhanced SBOM Standards and Interoperability

The SBOM formats continue to develop, with new versions adding capabilities for tracking provenance, build information, and security testing results. We're seeing convergence around best practices for what information SBOMs should contain, even as multiple formats continue to coexist. Tools for converting between formats and merging information from multiple sources are becoming more sophisticated.

Efforts are underway to standardize how SBOMs are shared between organizations. Initiatives like the Software Package Data Exchange (SPDX) spec and various industry working groups are developing protocols for SBOM distribution that balance transparency with security concerns about revealing too much information about internal systems.

Integration with Software Attestation

SBOMs are increasingly being paired with cryptographic attestation to verify both the contents of software and the integrity of the SBOM itself. This combination provides assurance that the SBOM accurately represents the software and hasn't been tampered with. Frameworks like SLSA (Supply chain Levels for Software Artifacts) and in-toto are defining how to create verifiable supply chain metadata that includes but extends beyond traditional SBOMs.

This trend toward verifiable SBOMs addresses a key weakness in current implementations - namely, that organizations must trust that the SBOM they receive accurately describes the software. Cryptographic attestation makes it possible to verify that claim independently, raising the level of assurance provided by SBOMs.

AI and Machine Learning Applications

Machine learning models are beginning to be applied to SBOM data for various purposes. Anomaly detection can identify unusual patterns in component usage that might indicate security issues or supply chain attacks. Predictive models can forecast which components are likely to develop vulnerabilities based on historical patterns and code characteristics.

These applications are still emerging, but they point toward a future where SBOM data feeds intelligent systems that provide proactive security recommendations rather than purely reactive vulnerability alerts. Organizations building large SBOM datasets today position themselves to leverage these capabilities as they mature.

What Are the Key Benefits of Implementing Software Bill of Materials (SBOM)?

The Software Bill of Materials delivers multiple critical benefits that justify the investment required for implementation. The primary benefit is dramatically improved visibility into your software composition. Without SBOMs, organizations operate with incomplete knowledge of what components their applications contain, particularly transitive dependencies that developers don't explicitly manage. This visibility gap makes vulnerability management reactive and slow, as security teams must investigate each application manually when new threats emerge.

SBOMs enable rapid vulnerability response by providing instant answers to questions like "which applications use the vulnerable Log4j library?" When critical vulnerabilities are disclosed, organizations with comprehensive SBOMs can assess their exposure across their entire application portfolio in minutes rather than weeks. This speed dramatically reduces the window during which attackers might exploit newly disclosed vulnerabilities.

License compliance represents another significant benefit of the Software Bill of Materials. Many open source licenses impose obligations on organizations that use them, such as requirements to publish source code or attribution requirements. SBOMs document the license associated with each component, making it straightforward to identify potential compliance issues before they become legal problems. This is particularly valuable for organizations that distribute software commercially, where license violations could result in costly litigation.

For organizations subject to regulatory requirements, SBOMs provide auditable evidence of due diligence in managing software security risks. Rather than making general claims about security practices, organizations can demonstrate specifically what components their software contains and show how they monitor those components for vulnerabilities. This documentation capability satisfies auditor requirements and reduces compliance burden.

‍

How Does Software Bill of Materials Support Compliance Requirements?

Software Bill of Materials have become central to various compliance frameworks and regulatory requirements across multiple industries. The United States government now requires SBOMs for software purchased by federal agencies, a mandate that emerged from executive orders focused on improving the nation's cybersecurity posture. This requirement has cascaded through the technology industry as vendors who sell to government agencies implement SBOM practices that then get applied to their commercial products as well.

Financial services regulators are increasingly expecting financial institutions to maintain detailed inventories of their software assets and demonstrate active management of software supply chain risks. While these requirements may not explicitly mandate SBOMs by name, the level of visibility and documentation they require is effectively achievable only through SBOM practices. Organizations can use their Software Bill of Materials to demonstrate compliance with these expectations during regulatory examinations.

Healthcare compliance frameworks including HIPAA don't currently mandate SBOMs specifically, but they require organizations to implement appropriate security controls for systems that process protected health information. Understanding what components these systems contain through SBOMs enables more effective security control implementation. When auditors ask how you ensure that vulnerabilities in third-party components are promptly addressed, SBOMs provide concrete evidence of your vulnerability management process.

The EU Cyber Resilience Act and similar emerging regulations worldwide are establishing new requirements for software security transparency. These regulations recognize that effective cybersecurity requires understanding what components software contains, making SBOMs a foundational element of compliance. Organizations that establish robust SBOM practices now position themselves to meet these requirements as they come into force rather than scrambling to achieve compliance under deadline pressure.

‍

What Tools and Processes Generate Software Bill of Materials Effectively?

Effective Software Bill of Materials generation requires both appropriate tooling and well-designed processes that integrate those tools into your development workflows. Software Composition Analysis tools represent the most common approach to SBOM generation, scanning application code and build artifacts to identify all components present. Tools like Snyk, Sonatype, Black Duck, and various open source alternatives can analyze applications built with different languages and frameworks, generating SBOMs in standard formats.

Build-time SBOM generation integrates directly into your CI/CD pipeline, creating a Software Bill of Materials each time an application is built. This approach ensures SBOMs stay synchronized with application changes automatically without requiring manual intervention. Tools like Syft, Tern, and various package manager plugins can be incorporated into build scripts to generate SBOMs as a standard build artifact alongside your application binaries or container images.

Container scanning tools play a specialized role in SBOM generation for cloud-native applications. Since containers package both application code and its runtime environment into a single image, container scanning tools examine the entire image contents to generate comprehensive SBOMs. Container registries including Docker Hub, Amazon ECR, and Google Container Registry increasingly offer built-in SBOM generation for images stored in their services.

The process side of effective SBOM generation is equally important as the tooling. Organizations need clear policies about when SBOMs should be generated, what format they should use, where they should be stored, and who's responsible for maintaining them. These processes should address edge cases like legacy applications that don't use modern build systems, commercial software acquired from vendors, and infrastructure components that may not fit standard application patterns. Establishing these processes early prevents inconsistency and gaps in SBOM coverage as your program matures.

Why Are Software Bill of Materials Critical for Medical Device Security?

Software Bill of Materials have become particularly critical in the medical device sector due to the unique combination of safety risks, regulatory requirements, and operational constraints that characterize this industry. Medical devices increasingly rely on software for core functionality, from insulin pumps that calculate and deliver doses to diagnostic imaging systems that help doctors identify diseases. Vulnerabilities in medical device software can directly impact patient safety, making security transparency through SBOMs a matter of life and death rather than merely business risk.

Medical devices typically have very long operational lifespans compared to typical IT equipment. A hospital might use the same MRI machine or patient monitoring system for ten or fifteen years, far longer than most software remains supported. During this extended operational period, components in the device software will inevitably develop newly discovered vulnerabilities. Without a Software Bill of Materials, healthcare providers and device manufacturers struggle to determine which specific devices are affected when new vulnerabilities are disclosed, leaving critical medical equipment potentially vulnerable or requiring extensive manual investigation to assess risk.

The FDA has recognized these challenges and now expects medical device manufacturers to maintain SBOMs for their products throughout the device lifecycle. This regulatory expectation reflects the understanding that software transparency is a prerequisite for effective medical device security management. When a vulnerability is discovered in a widely-used open source library, hospitals need immediate answers about whether their ventilators, anesthesia machines, or electronic health record systems are affected. The Software Bill of Materials provides those answers quickly and reliably.

Medical device manufacturers face particular challenges updating device software due to regulatory requirements around validation and approval. Every software change potentially requires regulatory submissions and clinical validation, making rapid patching impractical. SBOMs help manufacturers and healthcare providers make risk-based decisions about which updates are truly necessary versus which vulnerabilities can be mitigated through compensating controls. This visibility enables more informed decision-making about managing the tradeoffs between security currency and regulatory compliance.

‍

Strengthening Your Software Security Posture

The Software Bill of Materials has evolved from a niche security practice to a fundamental requirement for any organization serious about software security and supply chain risk management. As software continues eating the world and supply chain attacks become more sophisticated, the visibility provided by SBOMs is no longer optional - it's necessary for effective security operations.

Organizations that implement comprehensive SBOM practices position themselves to respond faster to emerging threats, satisfy increasingly stringent regulatory requirements, and demonstrate security maturity to customers and partners. The investment in tools, processes, and organizational change required to establish effective SBOM management pays dividends through reduced incident response costs, improved compliance posture, and decreased risk of catastrophic supply chain compromises.

Starting your SBOM journey doesn't require perfection from day one. Begin with pilot programs focused on critical applications, establish clear processes and quality standards, and gradually expand coverage across your application portfolio. The organizations that start building SBOM capabilities today will be prepared for the regulatory requirements and customer expectations that are rapidly becoming standard across industries.

The Software Bill of Materials represents a fundamental shift toward transparency in software security, acknowledging that you can't protect what you can't see. By embracing this transparency and building the capabilities to generate, manage, and act on SBOM data, organizations take a crucial step toward resilient software supply chains that can withstand the sophisticated threats facing modern enterprises.
