Public story · 2026-03-06 · source-backed
Two competing models for AI-powered security shipped on the same day. OpenAI launched Codex Security ("Aardvark") — an AI AppSec agent that builds project-specific threat models, then hunts for vulnerabilities and tests them in isolated environments. 30-day beta: 1.2M+ commits scanned, 792 critical findings, 14 CVEs in OpenSSH/GnuTLS/Chromium, 84% noise reduction. Meanwhile, Anthropic and Mozilla announced that Claude Opus 4.6 found 22 Firefox CVEs in two weeks from 112 bug reports, including 14 high-severity bugs — roughly a fifth of Mozilla's 2025 high-severity fixes. The find-vs-exploit asymmetry is notable: Claude found bugs in 20 minutes but generated working exploits in only 2 of several hundred attempts (~$4K in API credits). AgentShield's benchmark adds context: across 537 test cases against 6 commercial agent security products, most catch 95%+ of prompt injections but miss most unauthorized tool calls. Tool abuse detection is the weakest category across the board. (OpenAI | Anthropic | AgentShield)
