    • +
  • AI-assisted query generation with GitHub Copilot
    • +
  • Real-time analysis in pull requests
    • +
+
+
+
+
+

+ +

+
+
+ Multi-layer Secret Detection - Protects against credential exposure with advanced pattern matching. +
    +
  • 300+ partner patterns for cloud providers and services
    • +
  • Custom pattern support for proprietary secrets
    • +
  • Push protection to prevent secrets from entering repositories
    • +
  • Historical scanning of entire repository history
    • +
  • Automatic partner notifications for validated leaks
    • +
+
+
+
+
+

+ +

+
+
+ Comprehensive Dependency Management - Identify and remediate vulnerabilities in your software supply chain. +
    +
  • Automated dependency updates via Dependabot
    • +
  • Vulnerability alerts with CVE details and remediation
    • +
  • License compliance tracking
    • +

+ DevSecOps Best Practices with GHAS +

+
+
+
+
+
Shift Left Security
+

Integrate security scanning early in the development lifecycle, enabling developers to identify and fix vulnerabilities before they reach production.

+ +
Automated Security Gates
+

Implement automated checks in CI/CD pipelines to block PRs with critical vulnerabilities or exposed secrets.

+ +
Developer Training
+

Use GHAS findings as teaching moments to improve team security awareness and coding practices.

+
+
+
Custom Security Policies
+

Create organization-specific CodeQL queries to detect patterns unique to your codebase and compliance requirements.

+ +
Continuous Monitoring
+

Enable real-time security scanning on all branches to catch issues immediately as code is committed.

+ +
Incident Response
+

Leverage security advisories and automated notifications to rapidly respond to newly disclosed vulnerabilities.
