GitHub Advanced Security (GHAS)

GitHub-native security suite, bundling three checks directly into the repo/PR workflow rather than a separate pipeline stage: code scanning (CodeQL (unresolved) — SAST, semantic queries over a code graph), Dependabot (unresolved) (SCA — dependency CVE alerts + auto-PR updates), and secret scanning (detects committed credentials, can block pushes pre-merge). Overlaps with Snyk's SCA/SAST coverage but is tightly integrated into GitHub itself (PR checks, branch protection) rather than a third-party gate — many orgs run both, or pick one per project based on whether depth (Snyk) or native integration (GHAS) matters more.

GitHub's 2026 Secure Open Source Fund report (50 maintained OSS projects, 71 maintainers) framed this as the baseline security layer AI-assisted maintenance still depends on: GitHub_Copilot (unresolved) sped up triage and remediation of the alerts these tools generate, but maintainer judgment stayed the deciding factor on what actually shipped. Reported program-wide impact: 4,210 CodeQL alerts fixed, 1,500+ Dependabot updates applied, 650+ exposed secrets resolved, 533 new CVEs disclosed.
