Why Verizon Has Joined Anthropic’s AI Cyber Coalition

Cybersecurity has become one of the telco industry’s biggest balancing acts.

The same AI systems capable of detecting software flaws in seconds are also raising fears about how quickly those vulnerabilities could be exploited at scale.

Now, Verizon is stepping deeper into that debate.

The US telco giant has joined Anthropic’s Project Glasswing initiative, a cross-industry effort designed to strengthen critical infrastructure against emerging AI-driven cyber threats.

The move places Verizon alongside technology and security firms including Cisco, CrowdStrike, Microsoft and Palo Alto Networks.

At the heart of the initiative is Claude Mythos Preview, Anthropic’s limited-release frontier AI model, which the company says has already uncovered thousands of zero-day vulnerabilities across major operating systems and browsers.

AI Meets Network Security

Dan Schulman, Verizon CEO, says: “Our customers rely on the security of our network every day. As part of Project Glasswing, we are able to test and improve our cybersecurity efforts with new insights to maintain our network’s security." 

Anthropic launched Project Glasswing following the introduction of Claude Mythos Preview, under restricted release because of the sensitivity of its capabilities.

“Glasswing is built around Claude Mythos Preview, our new limited-release frontier model, which has so far found thousands of zero-day vulnerabilities – including some that survived decades of human review – spanning every major operating system and browser,” notes Daniela Amodei, President at Anthropic, on LinkedIn.

The announcement reflects growing concern across telcos about how AI could reshape both cyber defence and cyber risk.

Operators sit at the very core of national infrastructure, making them attractive targets for increasingly sophisticated attacks.

At the same time, AI tools are accelerating how quickly security teams can identify, test and patch vulnerabilities across large-scale networks.

Securing Critical Infrastructure

Project Glasswing brings together AI developers, cybersecurity specialists, software companies and governments with the aim of protecting critical infrastructure from AI-enabled threats.

Verizon says its internal information security teams have spent months testing the technology before joining the initiative.

“Over the past several months, our information security team has been rigorously testing this critical new technology to determine its benefits to our network,” Dan says.

“By using Mythos Preview, we are uniquely positioned to share cross-industry insights that will help secure the global internet fabric and support our mission to deliver a safe and reliable experience for every customer.”

Anthropic argues that collaboration between industries will become more important as advanced AI cyber capabilities become more widely available.

“AI cyber capabilities at this level will proliferate over the coming months and not every actor who gets access to them will be focused on defence. That's the gap Glasswing is built to close,” Daniela adds.

“Cyber defence at this scale is a team effort. Frontier labs, software companies, security researchers, open-source maintainers and governments all working together is how defenders will stay ahead.”

The initiative signals how AI is becoming embedded within network security operations, not simply as a productivity tool but as part of frontline cyber defence.
