Anthropic is expanding access to its most advanced frontier model, Mythos, to roughly 200 organizations through Project Glasswing.
Through the expansion, access to Claude Mythos Preview — Anthropic’s model for identifying software vulnerabilities in codebases — will be granted to around 150 additional organizations, all of which must clear security requirements before joining. Participating organizations now span more than 15 countries, with Anthropic signaling plans to broaden that geographic footprint going forward.
Justin Beals, CEO & Founder, Strike Graph, an AI-native GRC and compliance management platform:
“Controlled rollout of frontier AI is the right instinct. But opacity is not a security strategy. Anthropic has published some metrics, and that’s a start, but the validation methodology is self-selected. They chose which findings to send for independent review, and the reviewers were contractors they hired. The broader security community needs access to independent, third-party evaluation across the full corpus. As these tools become more capable, the organizations cleared to use them become high-value targets. Access without continuous compliance validation is just a slower version of the same risk. Whoever gets access, the standard should be verifiable transparency, not curated receipts.”
I for one am cautiously optimistic. But I have see more in terms of controls coming from Anthropic before I feel 100% comfortable.

Anthropic’s Glasswing rollout is a good start — but access isn’t the same as ongoing security
