Operational technology providers and their industry groups have been pressing for access to Anthropic’s cybersecurity-focused Mythos Preview model, arguing the initial rollout — which focused on major tech and finance firms under a global vulnerability patching effort — left out a widely exposed segment of critical infrastructure that’s often targeted by hackers.
In recent weeks, OT industry representatives have expressed frustration during roundtables and listening sessions about their initial exclusion from Project Glasswing, Anthropic’s initiative with major companies designed to secure critical software across the globe using the Mythos model, according to four people familiar with the discussions.
The processes for these firms to be granted access are ongoing, two of the people said. All of the sources requested anonymity because the discussions are private.
American Water, one of the nation’s largest regulated U.S. water and wastewater utilities, is among several organizations that have recently met with the Office of the National Cyber Director to discuss Mythos and broader AI-cybersecurity threats, said one of the people. American Water heavily relies on and oversees complex operational technology systems to manage its water treatment and distribution infrastructure.
“There’s definitely an annoyance in the OT world,” that person said. “That doesn’t mean people aren’t considering the needs of OT,” they noted, but decisionmakers dictating initial Glasswing access “weren’t thinking in those terms.”
Nextgov/FCW has asked Anthropic, ONCD and American Water for comment.
Operational technology, which is embedded in critical infrastructure everywhere, is a constant point of concern for cyberdefenders because it underpins essential everyday services like energy, water and transportation. Disruptions to those systems can have immediate real-world consequences.
