Secure your codebase with human-led audits

Automated scans for assessing at scale, human experts for assessing in-depth. Code Security Audit ensures nothing slips through the cracks.

Advanced source code audits by expert engineers

HackerOne Code Security Audit (CSA) offers detailed source code audits and code-assisted (white box) pentesting on your codebase by a network of over 600 vetted senior software engineers. This expert team uncovers deep-rooted vulnerabilities that automated tools may miss, and offers tailored remediation guidance to address design and implementation issues early—whether for a major release or compliance assurance.

Key Benefits

Comprehensive codebase protection

Review legacy codebases, prepare for major releases, and ensure compliance with standards and frameworks like NIST, FS-ISAC, and PCI DSS through expert-led audits.

Expert reviewers and agile delivery

Access a global network of 600+ vetted engineers, initiate engagements in as little as 4 days, and benefit from real-time feedback and collaboration.

Tailored support and remediation

Get dedicated technical support, granular access controls, and actionable remediation guidance for efficient vulnerability resolution.

How It Works

Scoping and setup

The process begins by setting up secure access to your source code repositories hosted on premises and platforms such as GitHub, GitLab, Azure DevOps, and Bitbucket. A dedicated member of your HackerOne team confirms the scope and ensures the code is properly prepared for review.

Codebase analysis and preparation

HackerOne sources the most qualified reviewers from our network of 600+ vetted experts based on your specific codebase and requirements. The reviewers use best-in-class repository scanning tools to build a contextual understanding of your code.

Human-led and automation-assisted review of code at scale

Automated coverage includes software composition analysis (SCA), static application security testing (SAST), infrastructure as code (lac) scanning, and secrets detection. Experts review these automated processes to identify critical focus areas and delve deeply into novel issues within large codebases. Manual code review, adhering closely to the OWASP Code Review Guide, uncovers multifaceted vulnerabilities and design flaws that automated tools may miss.

Reporting and remediation

You receive a detailed PDF report outlining identified vulnerabilities, their severity, and actionable remediation guidance. HackerOne also facilitates the review of code changes to validate mitigation.
