Claude Security's vulnerability scanning moves onto Anthropic's most cyber-capable model

Reported on 21 August 2026: Anthropic has moved Claude Security's code scanning onto Claude Mythos 5, its most cyber-capable model, and opened it as a public beta to Claude Enterprise customers — switched on from inside the product, with no separate model add-on and no direct model access for the security team using it.

What it means A frontier model reaching security teams as a product switch, rather than as an API they have to wire up themselves, is how capability actually lands in a security org.
