HackerOne Code Security Audit is a comprehensive source code analysis service that combines automated scanning and manual code review from over 600 vetted security experts to identify vulnerabilities in source code. The solution integrates with repository providers and DevOps processes, performing both automated scanning (including SAST and SCA) and expert manual review to detect security flaws early in the software development lifecycle. Engineers examine source code for security vulnerabilities, identify risks, validate findings, and provide remediation guidance, resulting in median savings of $18,037 per vulnerability compared to finding the same issue post-release through bug bounty programs. The service supports code bases regardless of size, age, or technology stack.
