Verizon joins Anthropic's Project Glasswing - Telecoms

Verizon has become the first telecommunications company to join Anthropic's Project Glasswing, an initiative established to investigate the cybersecurity implications of the Claude Mythos Preview model. The partnership was announced on May 19, 2026, by Telecoms.com. Verizon will test the model to improve network security, according to the announcement.

Project Glasswing was created by Anthropic to study the risks and potential benefits of its powerful Claude Mythos model, which has advanced capabilities in identifying previously unknown flaws in IT systems. Verizon is the first telecom operator to participate in the project, though other companies from various sectors have also joined.

The agreement allows Anthropic to gather real-world data on how a frontier AI model interacts with critical telecommunications infrastructure. Verizon will assess whether Mythos can help detect vulnerabilities more effectively than existing security tools. The results of these tests could influence how telecoms deploy AI for cybersecurity in the future.
