Anthropic says it will extend Project Glasswing to organizations in 15+ countries, sources say giving Mythos access to Five Eyes, NATO, Samsung, SK, and others
About 150 organisations will be given advanced cyber security model following requests from around the world
Financial Times
Context & Ripple Effects
Project Glasswing began as a restricted program: Claude Mythos Preview was offered to more than 40 organizations maintaining critical software rather than released broadly. Its launch network included major cloud, chip, security, and platform companies, alongside usage credits and support for open-source security groups.
The reported expansion follows European interest in access through ENISA, suggesting the program is moving from an initial critical-software cohort toward a wider set of public-sector and strategic-industry users while retaining controlled distribution.
First-order effects
About 150 organizations across more than 15 countries would gain access to Anthropic's advanced cybersecurity model, substantially enlarging the immediate user base beyond the initial cohort.
Five Eyes and NATO-linked users, as well as named corporate recipients such as Samsung and SK, would become part of a controlled access network for Mythos rather than waiting for general availability.
Second-order effects
Existing Glasswing partners in cloud, cybersecurity, and enterprise infrastructure gain a larger prospective base for integrating, supporting, or securing deployments around the program.
The expansion increases pressure on other frontier-model providers and cyber vendors to offer credible controlled-access pathways for sensitive security capabilities, particularly for government and critical-infrastructure customers.
Third-order effects
If access continues to broaden through vetted organizations rather than a general release, advanced cyber models could develop as a governed enterprise-and-state market, with access controls and institutional partnerships becoming a competitive differentiator.
Cross-border participation by security agencies and alliances may make interoperability, assurance, and rules for handling sensitive model outputs more central to AI-cyber adoption; the eventual balance between shared defense and misuse risk remains unresolved in the coverage.
The trend: This is one data point in the shift from broadly available AI tools toward selectively deployed frontier cyber capabilities governed through trusted institutional networks.
not a single crypto company has access to claude mythos imagine what happens when the wrong people get access and start hunting defi protocols and bridges. if you're building in crypto: get audits. multiple. now
We're expanding Project Glasswing. We've extended access to Claude Mythos Preview to approximately 150 additional organizations, based in more than fifteen countries. Read more about this expansion and our future plans for Project Glasswing: https://www.anthropic.com/...
We're expanding Glasswing today. To solve such a big/complex/urgent problem, we need Mythos-level capabilities in as many defenders' hands as possible. That's why we're working on safeguards to scale that safely ASAP. 11 of my reflections from the past 2 months of Glasswing 🧵:
NEW: Canada now has access to Mythos hacking tech and are officially part of Project Glasswing. “It's a very important step for Canadians and for our government to make sure we have access and we can protect our institutions and our country,” AI Minister @EvanLSolomon says
- Cyber safeguards are a hard + urgent techno-philosophical problem. - ...but powerful models w/o safeguards may come soon (~3, 6, 18 months max?). We need to scale access to defensive tools urgently. - Industry, government, maintainers, and researchers are taking this moment
- Mythos finds a lot of vulnerabilities. Patching is the bottleneck. - Industry/maintainers are very creative at self-organizing prioritizing/finding/fixing. - Mythos will look dumb in 6-12 months.
- Glasswing has been a rallying mission for Anthropic. Our team is incredible. - ...and we want to do whatever we can to kickstart the orgs/tools/initiatives that cyberdefenders need. Glasswing will probably seem very tiny within 6 months. Working on the latter right now!
- We've seen orgs can go from 0 -> 100 on model-powered cyberdefense in days (sometimes same day). - You don't need Mythos to get started. Claude Security & 4.8 make it really easy. - Partners use it not just for vuln remediation, but pentesting, threat intel, DNR, and more.
