Developer Briefing — GitHub launches Code Scanning beta with CodeQL

Executive briefing: GitHub opened a limited public beta of native Code Scanning on 6 May 2020. The release embeds CodeQL analysis into repositories so security issues are flagged inside pull requests and the Security tab without requiring separate tooling.

What changed

• Workflows can run CodeQL queries via GitHub Actions or external CI systems and publish results using the SARIF 2.1.0 standard.
• Alerts are triaged within GitHub, showing dataflow traces and allowing developers to dismiss, fix, or create issue tasks.
• Language support covered popular ecosystems including JavaScript/TypeScript, Python, Java, and C/C++, with extensibility for custom queries.

Why it matters

• Surfacing code analysis directly in pull requests reduces time-to-remediation and fosters secure coding habits without context switching.
• Standardized SARIF output enables correlation with existing application security orchestration and reporting tools.
• The beta signaled GitHub’s commitment to native supply-chain security features later expanded through Advanced Security.

Action items for operators

• Enable the beta workflows on critical repositories and baseline existing findings to avoid alert fatigue.
• Train developers on triage flows and integrate code scanning alerts into issue management for accountability.
• Develop custom CodeQL queries for organization-specific patterns, validating performance in CI before broad rollout.
