Checkmarx Taps Anthropic’s AI to Accelerate Vulnerability Detection…

Event summary

Checkmarx joined Anthropic’s Project Glasswing on September 3, 2026, gaining access to Claude Mythos 5 for defensive cybersecurity work.
The company will use the AI model to strengthen its vulnerability detection and share insights with the broader security community.
A J.P. Morgan analysis found that 80% of exploitations occur on or before the day a vulnerability becomes public, highlighting the urgency of faster detection.
Checkmarx aims to close the gap between software development pace and security tooling capabilities.

The big picture

Checkmarx’s participation in Project Glasswing reflects a broader industry shift toward leveraging AI to address the growing gap between rapid software development and slower security tooling. As exploitations increasingly occur before vulnerabilities are publicly disclosed, the use of frontier AI models like Claude Mythos 5 could redefine the landscape of application security. The strategic move positions Checkmarx as a leader in AI-driven cybersecurity innovation, with potential implications for both its competitive standing and the broader security ecosystem.
