Anthropic Launches Claude Code Security as Cybersecurity Shares Fall

The limited research preview uses Opus 4.6 to autonomously surface complex software flaws and propose patches under human oversight with multi-stage verification.

Overview

  • Claude Code Security is live in a limited research preview for Enterprise and Team customers, with expedited access offered to open‑source maintainers.
  • The tool scans entire codebases, reasons about component interactions and data flows, and provides targeted patch suggestions that require developer approval.
  • Anthropic says every finding is re‑checked through layered verification with severity and confidence ratings before reaching analysts to reduce false positives.
  • Internal testing with Opus 4.6 uncovered more than 500 previously unknown vulnerabilities in production open‑source projects, with triage and responsible disclosure ongoing.
  • Investors sold off cybersecurity stocks after the announcement, with JFrog down about 24% and declines reported for CrowdStrike, Okta, GitLab, Cloudflare, Zscaler, Palo Alto Networks and others, even as outside researchers caution that experienced humans remain essential for higher‑level threats.
