Container Image Scanning

Container image scanning is an important element of modern software supply chain security. DevSecOps teams rely on this critical process to identify security weaknesses within container images before they reach production systems. 

By definition, it’s a security process that examines containerized application images for vulnerabilities, misconfigurations, and compliance issues before deployment to production environments.

As organizations accelerate their adoption of containerized applications and microservices architectures, the need to systematically analyze container images for vulnerabilities has never been more pressing. This comprehensive examination process helps security directors and development team leads prevent the deployment of compromised or vulnerable code that could expose their infrastructure to attacks.

‍

What is Container Image Scanning?

Container image scanning represents the automated security analysis of container images to detect known vulnerabilities, exposed secrets, malware, and configuration problems. This scanning process examines every layer of a container image, from the base operating system through application dependencies and custom code. The technology works by comparing the contents of container images against vulnerability databases, security benchmarks, and organizational policy requirements.

The scanning mechanism operates at multiple levels within the container structure. When a container image gets built, it consists of numerous layers stacked together, each representing a set of filesystem changes. A comprehensive scanning solution analyzes each layer independently, identifying the software packages, libraries, and files present. The scanner then cross-references these components against continuously updated vulnerability databases like the National Vulnerability Database (NVD), vendor-specific advisories, and security research feeds.

Modern container image scanning goes beyond simple vulnerability detection. Advanced scanning platforms perform static analysis of application code, check for hardcoded credentials and API keys, validate configurations against security best practices, and ensure compliance with regulatory requirements. This multi-dimensional approach provides DevSecOps leaders with a complete security posture assessment before any container reaches a runtime environment.

‍

Understanding the Container Image Scanning Process

The container image scanning workflow integrates into various stages of the software development lifecycle. Teams can perform scanning at multiple checkpoints, creating layers of security validation that catch issues early and prevent vulnerable containers from progressing through the pipeline.

Pre-Build Scanning Strategies

Before container images even get constructed, security-conscious organizations scan base images and dependencies. This proactive approach allows development teams to select secure foundation layers for their applications. Base image scanning helps teams choose minimal, hardened images that reduce the attack surface from the start. Many organizations maintain approved base image repositories where only pre-scanned and verified images are available for developers to use.

Build-Time Image Analysis

During the container build process, automated scanning can halt builds that introduce critical vulnerabilities or violate security policies. This integration with CI/CD pipelines creates an immediate feedback loop for developers. When a build process pulls in a vulnerable library or misconfigures a container, the scanning system detects the issue and prevents the image from being tagged or pushed to a registry. This shift-left security approach reduces the cost and complexity of fixing vulnerabilities by catching them when developers have the context fresh in their minds.

Registry Scanning Operations

Container registries serve as the central storage locations for container images. Continuous registry scanning monitors images stored in these repositories, detecting newly disclosed vulnerabilities that affect previously scanned images. Since new vulnerabilities get discovered constantly, an image that was secure yesterday might have known exploitable weaknesses today. Registry scanning ensures that your image inventory remains under constant security surveillance, alerting teams when action needs taken.

Runtime Scanning Capabilities

Some advanced scanning solutions extend protection into the runtime environment, monitoring running containers for unexpected changes or malicious activity. Runtime scanning complements pre-deployment analysis by detecting issues that only manifest during execution, such as containers that attempt to access sensitive resources or exhibit suspicious network behavior.

‍

Explanation of Vulnerability Detection Methods

Container image scanners employ several detection techniques to identify security issues. Understanding these methods helps security teams evaluate scanning solutions and interpret results effectively.

Package-Based Vulnerability Identification

The most common scanning approach involves extracting the list of installed software packages from container images and matching them against known vulnerability databases. The scanner identifies the package manager used (such as apt, yum, apk, or pip), reads the package manifest, and compares each package version against vulnerability records. This method works well for detecting known CVEs in operating system packages and common application dependencies.

Language-Specific Dependency Analysis

Modern applications rely heavily on language-specific dependency managers like npm, Maven, PyPI, and RubyGems. Sophisticated scanners parse dependency files (package.json, pom.xml, requirements.txt, Gemfile) to build a complete dependency tree, including transitive dependencies that your direct dependencies require. This comprehensive analysis reveals vulnerabilities hidden deep in the dependency chain that developers might not even know their applications use.

Binary and File-Level Scanning

Not all software gets installed through package managers. Custom compiled binaries, third-party tools, and proprietary applications require different analysis techniques. Advanced scanners can fingerprint binary files, calculate cryptographic hashes, and match them against vulnerability databases. This binary analysis catches security issues in components that don't appear in standard package manifests.

Configuration Security Assessment

Beyond vulnerability detection, scanners evaluate container configurations against security benchmarks like the CIS Docker Benchmark. This assessment checks for containers running as root, excessive privilege grants, exposed ports, insecure volume mounts, and other configuration risks that could be exploited even without a vulnerability present. Runtime security configurations require particular attention as they directly impact the blast radius of potential compromises.

‍

How Container Image Scanning Integrates with DevSecOps Workflows

Effective container image scanning doesn't operate in isolation. The technology must integrate seamlessly into existing development workflows to provide value without creating friction that slows delivery velocity.

CI/CD Pipeline Integration

The most impactful integration point for container scanning sits within CI/CD pipelines. Modern scanning tools provide plugins or API integrations for popular CI/CD platforms like Jenkins, GitLab CI, GitHub Actions, Azure DevOps, and CircleCI. These integrations allow teams to add scanning as a pipeline stage that automatically runs whenever a container image gets built. Pipeline integration enables policy enforcement, where builds fail automatically if critical vulnerabilities are detected or compliance requirements aren't met.

Security directors should work with development leads to establish sensible policy thresholds that balance security with development velocity. A common approach involves blocking critical and high-severity vulnerabilities while creating tickets for medium and low-severity issues. This graduated response prevents security from becoming a bottleneck while still maintaining appropriate risk management.

Developer Tooling Integration

Providing developers with scanning capabilities within their local environments accelerates issue resolution. Command-line scanning tools and IDE plugins allow developers to scan images on their workstations before committing code. This immediate feedback helps developers build secure containers from the start, reducing the number of issues that reach CI/CD pipelines. When developers can scan locally, they take ownership of security rather than viewing it as a gate imposed by security teams.

Registry and Artifact Repository Connections

Container image scanning tools need direct integration with container registries like Docker Hub, Amazon ECR, Google Container Registry, Azure Container Registry, and private registry solutions like Harbor or Artifactory. Securing software artifacts throughout their lifecycle requires continuous monitoring of registry contents. These integrations enable automatic scanning of newly pushed images, scheduled rescanning of existing images, and webhook-triggered scans when vulnerability databases update.

Security Information Management

For enterprise environments, container scanning results should flow into centralized security information and event management (SIEM) systems, vulnerability management platforms, and security orchestration tools. This integration provides security operations teams with visibility into container security posture alongside other security signals. When scanning tools integrate with ticketing systems like Jira or ServiceNow, security findings automatically create actionable work items assigned to the appropriate teams.

‍

Key Components of Effective Container Image Scanning Solutions

Selecting the right container image scanning solution requires understanding the features that separate basic vulnerability detection from comprehensive container security. DevSecOps leaders should evaluate solutions against these critical capabilities.

Comprehensive Vulnerability Coverage

The scanning solution should maintain up-to-date vulnerability intelligence from multiple authoritative sources. Look for tools that aggregate data from the National Vulnerability Database, operating system vendor security advisories, language-specific security databases, and commercial threat intelligence feeds. The scanner should detect vulnerabilities across all layers of the container stack, from the base OS through application frameworks and dependencies.

Accuracy and False Positive Management

Vulnerability scanners struggle with accuracy. False positives waste developer time investigating non-issues, while false negatives create security gaps. Quality scanning solutions employ techniques to improve accuracy, such as confirming that vulnerable code paths are actually reachable, verifying package versions through multiple methods, and providing detailed evidence for each finding. The tool should allow teams to mark false positives and create exceptions with proper justification and expiration dates.

Policy-Based Governance

Organizations need flexible policy engines that encode security requirements as enforceable rules. A robust policy framework allows teams to define different requirements for different environments (development vs. production), application risk tiers, and compliance contexts. Policies might specify that no critical vulnerabilities are allowed in production, containers must not run as root, or specific licenses are prohibited. The scanner should enforce these policies automatically and provide clear explanations when policy violations occur.

Remediation Guidance

Detecting vulnerabilities only provides value if teams know how to fix them. Quality scanning solutions offer actionable remediation advice, such as specific package versions that resolve vulnerabilities, alternative libraries without known issues, and links to detailed security advisories. Some advanced platforms even generate pull requests with fixes automatically, dramatically reducing the time from detection to resolution.

Performance and Scalability

Large organizations build thousands of container images daily. The scanning solution must handle this volume without becoming a bottleneck. Look for architectures that support distributed scanning, caching of layer analysis results, and incremental scanning that only analyzes changed layers. The platform should scale horizontally to accommodate growing container workloads.

‍

Common Challenges in Container Image Scanning Implementation

Despite the clear security benefits, organizations face several obstacles when implementing container image scanning programs. Understanding these challenges helps teams plan successful deployments.

Alert Fatigue and Prioritization

Container images often contain hundreds of vulnerabilities, overwhelming development teams with security findings. Not all vulnerabilities present equal risk. A critical vulnerability in a package that your application never uses poses less practical risk than a medium-severity issue in actively executed code. Teams need strategies to prioritize vulnerabilities based on exploitability, reachability, and business context rather than just severity scores.

Legacy Image Management

Organizations accumulate large inventories of container images over time. Older images built months or years ago contain outdated packages with numerous known vulnerabilities. Scanning these legacy images reveals significant security debt that can't be addressed immediately. Teams need processes to systematically rebuild and update critical images while decommissioning unused containers that no longer serve business purposes.

Base Image Strategy

Many vulnerabilities originate in base images that multiple applications share. When a vulnerability appears in a widely-used base image, it affects every container built from that base. Organizations need governance around base image selection, regular updates, and a process to rebuild dependent images when base images change. Some teams create "golden images" that receive regular security updates and mandate their use across development teams.

Vulnerability Disclosure Timing

Scanning tools can only detect publicly disclosed vulnerabilities. Zero-day vulnerabilities and security issues not yet published in vulnerability databases won't be caught by scanning. This limitation means container image scanning must be part of a layered security approach that includes runtime protection, network segmentation, and security monitoring. Supply chain security challenges extend beyond just scanning container images.

Tool Sprawl and Integration Complexity

Many organizations end up with multiple scanning tools that provide overlapping capabilities. One scanner might come bundled with their registry, another integrates with their CI/CD platform, and a third was selected by the security team. This fragmentation creates confusion about which results to trust, where to view findings, and how to enforce policies consistently. Consolidating on a unified platform or establishing clear tool responsibilities reduces this complexity.

‍

Best Practices for Container Image Scanning Programs

Successful container security programs follow proven practices that maximize the value of scanning while minimizing operational overhead.

Scan Early and Often

The earlier vulnerabilities get detected, the cheaper they are to fix. Implement scanning at multiple stages: during development on developer workstations, during the build process in CI/CD pipelines, continuously in registries, and before deployment to production. This multi-stage approach creates redundant security checks that catch issues regardless of where they're introduced.

Establish Clear Ownership

Every container image should have a designated owner responsible for addressing security findings. Without clear ownership, vulnerability reports go ignored and security issues accumulate. Teams should implement tagging standards that identify image owners, associated applications, and business purposes. When scanners detect issues, notifications should route to the appropriate development team with the context and access needed to resolve problems.

Create Feedback Loops

Security findings should reach developers through the tools and workflows they already use. Rather than requiring developers to check separate security dashboards, integrate findings into pull request comments, chat channels, and development task boards. When security becomes part of the natural development flow rather than a separate concern, teams address issues more quickly.

Measure and Report Progress

Track metrics that demonstrate the effectiveness of your container scanning program. Useful metrics include the average time from vulnerability detection to remediation, the percentage of deployed containers with no critical vulnerabilities, trends in vulnerability counts over time, and compliance with security policies. Regular reporting to leadership demonstrates the value of security investments and highlights areas needing additional resources.

Maintain Updated Vulnerability Intelligence

The effectiveness of container scanning depends entirely on the quality and currency of vulnerability data. Ensure your scanning solution receives regular updates to its vulnerability databases. Some organizations supplement open-source vulnerability data with commercial threat intelligence that provides earlier warnings about emerging threats. The scanning platform should update its vulnerability intelligence at least daily, with critical security issues triggering immediate updates.

Balance Automation with Human Judgment

While automation enables scanning at scale, human expertise remains necessary for interpreting results and making risk decisions. Not every detected vulnerability requires immediate action. Security teams should review findings, assess actual risk based on application architecture and usage patterns, and guide development teams on prioritization. Automated policy enforcement handles clear-cut cases, while security experts make judgment calls on complex situations.

‍

Advanced Container Image Scanning Techniques

As container security matures, advanced techniques extend beyond basic vulnerability detection to provide deeper security insights.

Software Bill of Materials Generation

Modern scanning solutions generate Software Bill of Materials (SBOM) documents that provide a comprehensive inventory of all components within container images. These machine-readable documents list every package, library, dependency, and file present in the image. Generating and managing SBOMs has become a critical compliance requirement for many industries and government contractors. SBOMs enable vulnerability management teams to quickly determine exposure when new vulnerabilities are disclosed, answering questions like "which of our containers use Log4j?" within minutes rather than days.

Malware and Secret Detection

Beyond known vulnerabilities, advanced scanners check for malware signatures and exposed secrets within container images. Malware detection uses pattern matching and behavioral analysis to identify potentially malicious code embedded in images. Secret detection scans for API keys, passwords, private keys, tokens, and other credentials that developers sometimes accidentally include in container images. Finding and removing these secrets before deployment prevents credential exposure that could compromise entire environments.

License Compliance Checking

Open source licenses carry obligations and restrictions that organizations must respect. Container scanning tools can identify the licenses associated with packages and dependencies, flagging licenses that conflict with organizational policies. Some licenses require making source code public or restrict commercial use, creating legal risk if not properly managed. Automated license compliance checking protects organizations from inadvertent license violations.

Image Provenance and Attestation

Supply chain attacks increasingly target container images. Attackers compromise build systems or registries to inject malicious code into trusted images. Advanced security programs implement image signing and verification to ensure containers come from trusted sources and haven't been tampered with. Scanning solutions that verify cryptographic signatures and provenance attestations provide assurance that images are authentic and haven't been modified since they were built.

Behavioral Analysis and Drift Detection

Some scanning platforms analyze container behavior to detect anomalies that might indicate compromise. By establishing baselines of normal container operation, these systems alert when containers exhibit unusual network connections, file system modifications, or process executions. This runtime behavioral analysis complements static image scanning by detecting threats that only manifest during execution.

‍

Container Image Scanning in Regulated Industries

Organizations in healthcare, financial services, government, and other regulated sectors face additional compliance requirements that impact their container scanning strategies.

Compliance Framework Mapping

Regulatory frameworks like PCI-DSS, HIPAA, SOC 2, and FedRAMP include requirements related to vulnerability management and secure software development. Container image scanning helps satisfy these requirements by demonstrating that organizations systematically identify and address security vulnerabilities before deploying applications. Security directors should document how their scanning program maps to specific compliance requirements, making audits more efficient.

Audit Trail and Evidence Collection

Regulated organizations need detailed records of security activities for audit purposes. Container scanning platforms should maintain comprehensive logs showing which images were scanned, when scanning occurred, what vulnerabilities were found, and what actions were taken. This audit trail demonstrates due diligence and helps organizations prove compliance with security requirements. Some industries require retaining these records for years, necessitating integration with long-term log storage and management systems.

Air-Gapped Environment Considerations

Organizations with strict security requirements sometimes operate air-gapped environments that lack internet connectivity. Container scanning in these environments requires special consideration. Vulnerability databases need manual updates, scanning tools must function without cloud connectivity, and processes must exist for transferring approved container images into the secure environment. Some scanning vendors provide on-premises solutions designed for these restricted environments.

‍

The Role of Container Image Scanning in Software Supply Chain Security

Container images represent a critical component of the modern software supply chain. Understanding how scanning fits into broader supply chain security efforts helps organizations build comprehensive protection strategies.

Software supply chains extend from open source dependencies through build systems, artifact repositories, deployment pipelines, and runtime environments. Each stage introduces potential security risks. Container image scanning addresses risks associated with third-party dependencies, vulnerable packages, and misconfigured deployments, but it doesn't secure the entire supply chain alone. Complete container security requires securing build systems that create images, protecting registries that store them, and monitoring runtime environments where they execute.

Recent high-profile supply chain attacks demonstrate that adversaries target build and distribution systems to compromise software before it reaches end users. Container image scanning detects the results of such compromises by identifying unexpected components, suspicious configurations, or known malware in images. When combined with build provenance verification, signing requirements, and access controls, scanning becomes part of a defense-in-depth strategy that makes supply chain compromises significantly harder to execute successfully.

‍

Measuring the Business Impact of Container Image Scanning

Security initiatives need to demonstrate business value. Container image scanning provides several measurable benefits that resonate with business leaders.

Risk Reduction Quantification

By tracking the number and severity of vulnerabilities detected and remediated, organizations can quantify risk reduction. Converting vulnerability counts into risk scores using frameworks like CVSS provides a metric that shows security posture improving over time. When briefing executives, security leaders can present data showing "we've reduced our critical vulnerability exposure by 75% since implementing container scanning," making abstract security improvements concrete.

Incident Prevention Value

Every vulnerability detected and fixed before deployment represents a potential security incident prevented. While proving a negative is challenging, organizations can estimate the cost of security incidents based on industry research and their own incident response expenses. When container scanning prevents deploying a critical vulnerability that could have led to a breach, the business value becomes clear even if the prevented incident is hypothetical.

Compliance Cost Reduction

Automated container scanning reduces the time and effort required for security audits and compliance assessments. Rather than manually inventorying container contents and researching vulnerabilities during audit season, organizations with mature scanning programs can generate reports on demand showing their security posture and remediation activities. This automation saves significant effort and reduces audit costs.

Developer Productivity Impact

While security scanning can slow initial development velocity as teams address findings, the long-term impact improves productivity. Catching vulnerabilities early, before they reach production, prevents expensive emergency patching and incident response. Developers spend less time troubleshooting security issues in production and more time building features. Well-implemented scanning programs with clear policies and good tooling integration ultimately accelerate secure development.

What Are the Different Types of Container Image Scanners Available?

Different types of container image scanners serve various needs within organizations. Container image scanning solutions range from open-source tools to commercial platforms, each with distinct capabilities. Open-source scanners like Trivy, Clair, and Grype provide basic vulnerability detection without licensing costs, making them popular for smaller teams or organizations beginning their container security journey. These tools typically focus on package-based vulnerability scanning and offer command-line interfaces that integrate with CI/CD pipelines.

Commercial container image scanning platforms offer advanced features beyond vulnerability detection, including policy enforcement engines, compliance reporting, license checking, and enterprise support. Vendors like Snyk, Aqua Security, Palo Alto Prisma Cloud, and Sysdig provide comprehensive solutions that scan containers alongside other application security concerns. Cloud provider-native scanners integrate directly with AWS ECR, Google Container Registry, and Azure Container Registry, offering convenient scanning for organizations heavily invested in specific cloud platforms.

Registry-integrated scanners come bundled with container registry solutions like Docker Hub, Harbor, and Artifactory. These scanners automatically analyze images as they're pushed to registries, providing continuous monitoring without additional infrastructure. The advantage of registry-integrated scanning lies in its automation and visibility - every image stored in the registry gets scanned without requiring developer action.

Runtime-focused scanners extend beyond pre-deployment analysis to monitor containers during execution. These tools detect vulnerabilities in running containers and identify suspicious behaviors that might indicate compromise. Runtime scanning complements static image analysis by catching issues that only manifest during operation, such as containers that violate security policies or exhibit malicious activity.

‍

How Does Container Image Scanning Differ from Traditional Vulnerability Scanning?

Container image scanning differs significantly from traditional vulnerability scanning in scope, methodology, and timing. Container image scanning analyzes packaged application artifacts before they run, examining the contents of container images layer by layer. Traditional vulnerability scanning typically targets running systems, networks, or deployed applications, identifying security weaknesses in operational infrastructure.

The timing difference creates distinct security advantages for container image scanning. By analyzing images before deployment, container scanning enables teams to prevent vulnerable code from reaching production environments. Traditional vulnerability scanning detects problems in systems already running, requiring remediation processes that might involve taking systems offline or coordinating emergency patching. Container image scanning shifts security left in the development lifecycle, catching issues when they're cheaper and easier to fix.

Methodologically, container image scanning examines static file systems and package manifests rather than actively probing running systems. Traditional vulnerability scanners send network requests, attempt authentication, and probe for weaknesses by interacting with live systems. Container scanning analyzes the contents of image layers without executing any code, making it faster and safer since there's no risk of disrupting running applications.

‍

The scope of analysis differs as well. Container image scanning focuses specifically on the contents of container images—packages, dependencies, configurations, and files included in the image. Traditional vulnerability scanning examines broader infrastructure components including network configurations, system patches, access controls, and application behaviors. Both approaches complement each other in comprehensive security programs, with container scanning handling pre-deployment artifact analysis and traditional scanning securing runtime infrastructure.

‍

What Vulnerabilities Can Container Image Scanning Detect?

Container image scanning detects a wide range of security vulnerabilities and misconfigurations that could compromise containerized applications. Container image scanning identifies known Common Vulnerabilities and Exposures (CVEs) in operating system packages, application libraries, and dependencies. These vulnerabilities receive unique identifiers and detailed descriptions in public databases, allowing scanners to match package versions against known security issues.

Application dependency vulnerabilities represent a major category that container image scanning addresses. Modern applications pull in hundreds of dependencies through package managers like npm, pip, Maven, and RubyGems. Scanners analyze dependency manifests and lock files to identify vulnerable versions of libraries, including transitive dependencies that developers might not directly reference but their chosen libraries require. A vulnerability several layers deep in the dependency tree can be just as exploitable as one in a direct dependency.

Configuration security issues get flagged by container image scanning tools that evaluate image settings against security best practices. Containers configured to run as root, expose unnecessary ports, grant excessive capabilities, or mount sensitive host directories all create security risks. Scanners compare container configurations against benchmarks like the CIS Docker Benchmark to identify these misconfigurations before deployment.

Embedded secrets and credentials frequently appear in container images when developers accidentally commit sensitive information. Container image scanning tools detect patterns matching API keys, passwords, private keys, database connection strings, and authentication tokens. These exposed secrets could allow unauthorized access to systems and data if containers get deployed or images get shared publicly.

Malware and suspicious executables sometimes get introduced into container images through compromised dependencies or malicious base images. Advanced scanners use signature-based detection and behavioral analysis to identify potentially malicious code within images. While less common than other vulnerability types, malware in container images represents a serious supply chain security threat that scanning helps mitigate.

‍

How Do You Implement Container Image Scanning in CI/CD Pipelines?

Implementing container image scanning in CI/CD pipelines requires thoughtful integration that provides security without disrupting development workflows. Container image scanning integration begins by selecting a scanner that provides plugins or API support for your CI/CD platform. Most modern scanning tools offer integrations with Jenkins, GitLab CI, GitHub Actions, CircleCI, Azure DevOps, and other popular platforms through native plugins or container-based executables that run as pipeline steps.

The typical implementation adds scanning as a dedicated stage in the pipeline that executes after the container image build completes. This stage runs the scanner against the newly created image, waits for analysis to complete, and evaluates results against defined policies. The pipeline configuration should specify what happens when vulnerabilities are detected—whether the build fails immediately, warnings get logged but the build continues, or different actions occur based on severity levels.

Policy configuration determines how scanner findings affect pipeline execution. Teams should establish clear criteria for what constitutes a build failure versus a warning. A common approach blocks builds containing critical or high-severity vulnerabilities with known exploits while allowing medium and low-severity issues to pass with notifications. Policies can be more nuanced, considering factors like whether fixes are available, whether vulnerable code paths are actually used, and the sensitivity of the application being built.

Authentication and access credentials require secure handling when integrating scanners into pipelines. The scanner needs access to the built container image, which might reside in a private registry requiring authentication. Credentials should be stored using the CI/CD platform's secrets management rather than hardcoded in pipeline definitions. Some organizations use service accounts with minimal required permissions specifically for scanning operations.

Result reporting and developer feedback complete the integration. When scans detect issues, developers need clear, actionable information about what was found and how to fix it. Effective integrations post scan results as pipeline artifacts, comments on pull requests, or notifications in team communication channels. The feedback should include vulnerability details, affected packages, available fixes, and links to additional information. Making scan results easily accessible within developer workflows increases the likelihood that issues get addressed quickly.

Container image scanning represents an indispensable security control for organizations deploying containerized applications at scale. By systematically analyzing images for vulnerabilities, misconfigurations, and compliance issues before deployment, teams prevent security problems from reaching production environments where they're more costly and disruptive to address.
