San Francisco, CA — Two weeks after Anthropic announced Claude Mythos, the cybersecurity industry has produced considerably more analysis of the announcement than Anthropic produced about the product itself. Most of it, remarkably, turned out to confirm whatever the author already believed.

In interviews conducted over the past two weeks, every vendor we spoke to described the announcement as unprecedented, before explaining that it reaffirms what they've been building all along.

"This is a paradigm shift that fundamentally changes everything about cybersecurity forever," said Marcus Holt, VP of Strategy at Bastion Labs, before clarifying that Bastion had actually been doing this exact thing since 2019. When asked how a product built on regex-based detection rules was equivalent to a frontier AI model, Holt described the question as "reductive."

The broader response has settled into three camps. Camp one believes Mythos will replace all security tooling within 18 months and that anyone not panicking is asleep. Camp two believes it's a nothingburger because Anthropic doesn't understand the "complexity of the enterprise security buyer." Camp three — by far the largest — has written 2,000-word LinkedIn posts that begin with Mythos as a hook before settling into whatever argument they were already planning to make that week.
