Claude Mythos, Opus 4.7, and Claude Security are not three stories. They are one architecture.
Three cybersecurity announcements in three weeks. Every outlet covered them as separate news. They are not.
I just published a full breakdown connecting the three layers of Anthropic's cybersecurity strategy:
The research tier — Claude Mythos Preview, restricted to 52 organizations in Project Glasswing. This model found thousands of zero-day vulnerabilities across every major OS and browser, including a 27-year-old OpenBSD bug. It is not publicly available and has no release date.
The platform tier — Claude Opus 4.7, available to everyone via the API. First Claude model with real-time cybersecurity safeguards. Offensive capabilities deliberately reduced compared to Mythos. Anthropic is using this tier to learn how to eventually deploy Mythos-class models more broadly.
The product tier — Claude Security, now in public beta for Enterprise customers. Scan your repos from the Claude.ai sidebar. Get findings with confidence ratings, severity, and reproduction steps. Generate patches and open them in Claude Code on the Web. No API integration required.
The partner angle is what surprised me most. CrowdStrike, Palo Alto Networks, SentinelOne, Wiz, and TrendAI are all embedding Opus 4.7 into their existing platforms. Anthropic is not trying to replace your security stack — it is powering it.
What if you are not an Enterprise customer? The article covers what you can do right now with Opus 4.7 via the API, and what the Cyber Verification Program offers for legitimate security researchers.
