Making frontier cybersecurity capabilities available to defenders

Product announcement dressed as research disclosure. Claude Code Security uses multi-stage self-verification to scan codebases beyond pattern-matching SAST. The 500-vuln claim has no CVEs, no false positive rates, and no comparison to existing tools. Zero external validation in the announcement itself -- the WSJ/Firefox piece did that work. The real play: security scanning as a loss-leader wedge for enterprise platform deals. Neither lab announced pricing.

Codex Security: now in research preview

Same-day competitive counter to Anthropic with stronger receipts: 15 named CVEs in the appendix (GnuTLS heap overflows, GnuPG stack buffer overflow, GOGS 2FA bypass), published improvement curves (84% noise reduction, 90%+ severity over-reporting reduction, 50%+ false positive reduction). The threat model architecture -- building an editable intermediate artifact before scanning -- is the most interesting pattern: it generalizes as "make the agent's understanding inspectable before execution." Broader tier access (Pro through Edu) weakens the dual-use containment narrative but maximizes adoption velocity.

Anthropic's AI Hacked the Firefox Browser. It Found a Lot of Bugs.

The independent credibility piece for Anthropic's security capabilities. Claude found 100+ Firefox bugs (14 high-severity) in two weeks -- more high-severity than the world reports to Mozilla in two months. The Curl counter-narrative is the buried lede: AI bug reports are 95% garbage (Stenberg data), making Claude's hit rate the real differentiator, not the volume. Most important detail: Claude is better at finding bugs than exploiting them -- the defender/attacker asymmetry currently favors defenders, but that gap is temporary.
