SonicWall Joins Anthropic's Project Glasswing

MILPITAS, Calif. – July 28, 2026 – 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.  

“Security vendors are not exempt from the pressure every software maker is under right now,” said Chandro Prasad, SonicWall Chief Product Officer. “Vulnerabilities move from disclosure to exploitation faster than most patch cycles can keep up with. Participating in Project Glasswing gives our security team another way to find and close gaps in our own code before an attacker does. That is the standard we hold ourselves to, and this program is a meaningful way to raise it further.”  

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 to help refine the framework for the broader cybersecurity community.  

“Attackers already share tools and techniques at scale, and it’s time that defenders do the same,” continued Prasad. “Programs like Glasswing work because participants commit to feeding what they learn back into the broader effort, not just using the access for their own  benefit.” 

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 – organizations that are frequent targets of attack. More information about the program is available at Anthropic's official announcement.
