Anthropic Joins Forces With Amazon, Microsoft, Apple on Cyber Defense AI

By  |  April 8, 2026

Artificial intelligence startup Anthropic on Tuesday unveiled a new initiative aimed at strengthening cybersecurity defenses through collaboration with major technology firms. The program, called “Project Glasswing,” will allow select partners to preview an advanced, unreleased AI model designed for defensive cybersecurity applications.

    The initiative includes participation from leading companies such as Amazon, Microsoft, and Apple, alongside cybersecurity and infrastructure players like CrowdStrike, Palo Alto Networks, Google, and Nvidia. Under the program, these organizations will gain early access to “Claude Mythos Preview,” a general-purpose AI model developed by Anthropic.

    According to Reuters, the model is being positioned specifically for defensive cybersecurity work, allowing partners to identify vulnerabilities and strengthen systems before threats can be exploited. The announcement comes shortly after a report last month highlighted internal testing of the Claude Mythos system, which raised concerns about both its powerful capabilities and potential risks, per Reuters. That earlier report contributed to a sharp decline in shares of cybersecurity firms including Palo Alto Networks and CrowdStrike.

    The timing of the initiative aligns with growing concern across the industry about the rapid evolution of AI-driven cyber threats. Discussions at this year’s RSA cybersecurity conference in San Francisco were heavily focused on whether traditional security tools remain sufficient in the face of increasingly sophisticated AI-powered attacks.

    In a company blog post, Anthropic said its Mythos Preview model has already identified “thousands” of significant vulnerabilities across operating systems, web browsers, and other widely used software. According to Reuters, the company plans to share these findings broadly with industry partners as part of its collaborative approach.

    Anthropic also announced plans to expand access to roughly 40 additional organizations responsible for critical software infrastructure. As part of the initiative, the company committed up to $100 million in usage credits and $4 million in donations to support open-source security efforts. Per Reuters, this funding is intended to accelerate defensive capabilities and promote stronger industry-wide resilience.

    The company said its long-term objective is to enable users to safely deploy advanced AI systems like Mythos at scale. It also noted that it has been in ongoing discussions with the U.S. government regarding the model’s capabilities and potential implications.

    The push for enhanced AI-driven security comes amid rising evidence of real-world threats. Last year, Anthropic disclosed that hackers had exploited vulnerabilities in its Claude AI system to target approximately 30 global organizations. Meanwhile, a joint study by IBM and Palo Alto Networks found that 67% of 1,000 surveyed executives reported being targeted by AI-based cyberattacks within the past year, according to Reuters.
