Anthropic expands Project Glasswing cybersecurity program to 150 more organizations

Anthropic PBC is expanding a program that enables organizations to test their cybersecurity defenses using its Claude Mythos Preview model.

The initiative, which is known as Project Glasswing, launched earlier this year with about 50 participants. The group included Microsoft, Nvidia Corp., Google LLC and prominent tech firms. Anthropic announced today that it has opened access to 150 more organizations.

The company says that the newly added participants include enterprises in the power, water, healthcare and communications sectors. The Financial Times reported that NATO and the European Union’s ENISA cybersecurity agency also received access.

Anthropic is limiting Claude Mythos Preview’s availability over concerns that it could be misused by hackers. However, some industry observers argue that the model’s phased rollout doesn’t fully mitigate cybersecurity risks.
