Making frontier cybersecurity capabilities available to defenders
Claude Code Security, a new capability built into Claude Code on the web, is now available in a limited research preview. It scans codebases for security vulnerabilities and suggests targeted software patches for human review, allowing teams to find and fix security issues that traditional methods often miss.Security teams face a common challenge: too many software vulnerabilities and not enough people to address them. Existing analysis tools help, but only to a point, as they usually look for known patterns. Finding the subtle, context-dependent vulnerabilities that are often exploited by attackers requires skilled human researchers, who are dealing with ever-expanding backlogs.
TL;DR
- Claude Code Security, a new AI capability, scans code for vulnerabilities and suggests software patches.
- It aims to help defenders address the overwhelming number of software vulnerabilities that traditional tools often miss.
- Unlike rule-based analysis, Claude Code Security understands code context like a human researcher.
- Findings are verified, rated for severity, and presented with suggested patches for human review and approval.
- The tool builds on over a year of research and testing of Claude's cybersecurity abilities.
- It has proven effective in finding long-undetected vulnerabilities in open-source codebases.
- Claude Code Security is available as a limited research preview to Enterprise and Team customers, with expedited access for open-source maintainers.
