The Pentagon's CTO Emil Michael stated that Anthropic remains a supply chain risk for U.S. national security, meaning its technology is considered a threat. However, the company's AI model Mythos, which has advanced cyber capabilities, is viewed as a distinct national security concern requiring network hardening to address its ability to find and patch cyber vulnerabilities. This follows a public dispute earlier this year when the Department of Defense blacklisted Anthropic, forcing defense contractors to avoid using its Claude models. The DOD still seeks negotiable guardrails for using Anthropic's technology, reflecting ongoing security and operational concerns.
