Anthropic is opening the door for the European Union Agency for Cybersecurity, known as ENISA, to access Claude Mythos, the company’s AI model built specifically to hunt software vulnerabilities at industrial scale.
Mythos was purpose-built to scan codebases and flag exploitable weaknesses. When Anthropic unveiled Claude Mythos Preview on April 7, 2026, the model can scan over 1,000 open-source projects and identify vulnerabilities at a pace and scale that no human security team could match.
What Mythos actually does, and why it matters
In its initial deployment, Mythos flagged approximately 23,019 total vulnerabilities across those projects. Of those, an estimated 6,202 were classified as high or critical severity.
To manage the risks of releasing something this powerful, Anthropic created Project Glasswing, a controlled rollout that restricted access to about 50 vetted partners. The roster includes Amazon, Microsoft, Apple, Nvidia, and JPMorgan among them.
