Overview
- Claude Code Security scans entire codebases, reasons about data flows like a researcher, runs multi‑stage self‑checks, and proposes patches that require developer approval.
- Access is limited to Enterprise and Team customers during the research preview, with expedited and free access offered to open‑source maintainers as Anthropic coordinates responsible disclosure.
- Anthropic’s Frontier Red Team reports Opus 4.6 uncovered more than 500 vulnerabilities in production open‑source projects, including long‑undetected high‑severity flaws now under triage.
- The announcement coincided with sharp sector declines, including JFrog down about 24%, CrowdStrike roughly 8%, Okta over 9%, and GitLab more than 8%, with other vendors also slipping.
- Anthropic acknowledges dual‑use risks and says it is investing in safeguards to detect malicious use, while independent researchers note the tool complements experts and often excels at lower‑impact findings; test participants must scan only code they have rights to.
