Security at every step

Native application security testing

Find and fix vulnerabilities 7x faster

With AI-powered application security testing tools embedded in your development workflow, GitHub Advanced Security outperforms non-native add-ons by delivering 7x faster remediation rates for identified vulnerabilities.

Secure your code

Detect security issues in your pull requests and prevent new vulnerabilities from entering main with automatic scans that leverage machine learning to continuously amp up accuracy.

Prioritize alerts and view exposure across the codebase to make sure you focus on what matters. Automatically resolve alerts with AI-powered auto-remediation.

Find vulnerabilities and suppress false positives with more than 2,000 queries from GitHub and the open-source community, or write your own queries for custom-curated results. Support for third-party scanning engines includes consolidated results in a single unified interface. Tackling a big project? Multi-repository variant analysis means you can run a single query on up to 1000 repositories at once.
