Anthropic puts Opus 5.5, Sonnet 5.5 and Mythos 5.1 behind three tiers of cyber verification

Anthropic's Cyber Verification Program now gives security teams three tiers of access to Claude Opus 5.5, Sonnet 5.5 and Mythos 5.1 for defensive work. Getting in takes organization verification and control attestations, and a team learns its tier only from its own admin view.

Anthropic routes frontier-model misuse alerts into the customer's own SOC queue

Anthropic cuts Fable 5.1 prices by 25% and launches two-tier safeguard system with Mythos 5.1

The saving comes off cache reads, so it lands unevenly across teams, and the model's most sensitive capability now reaches users through a credential issued by an access program, not a purchase order a budget holder can sign off alone. Both changes move the decision away from the budget holder.

Anthropic moves misuse monitoring into cloud storage its customers control

The company argues that catching sophisticated misuse means correlating data across sessions and accounts, and regulated buyers balked at holding that data with a vendor, so the store moves to their cloud.

Three July evaluation runs without standard safeguards gave Claude access to real systems

Anthropic places the three incidents inside cybersecurity evaluations, and reports that the checkpoint behind its deliberately reward-hacking Opus stayed clean on the same tests, which puts training practice in the control surface as well.
