SonicWall today confirmed it is a participant in Anthropic's Project Glasswing and is testing Claude Mythos 5 for defensive cybersecurity work. Through the initiative, SonicWall is applying the model to vulnerability discovery and code review across its own software to find and remediate security issues before they can be exploited. Project Glasswing is an Anthropic-led industry effort that gives participating security teams access to Claude Mythos 5, a frontier model not available to the general public, for defensive security research. Anthropic launched the program to help close the gap between attackers using AI to accelerate vulnerability discovery and defenders' ability to find and fix those same issues first. As part of the program, SonicWall's security research team is incorporating the model directly into its defensive testing workflows, while contributing findings and best practices back to Anthropic. Project Glasswing includes participants across the technology and critical infrastructure sectors. Through it, SonicWall is able to contribute its learnings from working with over 17,000 partners, including managed service providers and small and mid-sized businesses.
