Making frontier cybersecurity capabilities available to defenders

Claude Code Security, a new feature within Claude Code, offers a fresh approach to cybersecurity by scanning codebases for vulnerabilities and suggesting software patches for human review, addressing the challenge of too many vulnerabilities and insufficient personnel to manage them. Unlike traditional static analysis tools that rely on known patterns, Claude Code Security employs AI to understand code like a human researcher, identifying complex vulnerabilities that are often overlooked. This capability is released as a limited research preview to Enterprise and Team customers, with accelerated access for open-source maintainers, to refine its features and ensure responsible deployment. Each finding undergoes a multi-stage verification process with severity ratings to prioritize fixes, and nothing is implemented without human approval. Built on extensive research and stress-testing, Claude Code Security aims to enhance defensive capabilities in cybersecurity, allowing teams to work within familiar tools. The tool is part of a broader effort to increase security across the industry by leveraging AI to detect previously undetected bugs and reduce the risk of attacks.
