Rapid7 Gains Access To Anthropic’s Project Glasswing To Explore Frontier AI For Cybersecurity

Rapid7 has joined Anthropic's Project Glasswing, gaining access to Claude Mythos Preview to explore how frontier AI can support defensive cybersecurity workflows. The company is using the model internally across product security, vulnerability validation, zero-day research, and red-teaming. Rapid7 emphasizes that AI value in security depends on pairing model capabilities with expert oversight, operational context, and full-lifecycle workflows — from discovery through remediation and detection. The post also notes Anthropic's release of Fable 5, the first publicly available Mythos-class model.
