Claude expands verified cyber access into three tiers: HubAI change briefing

What this changes for UK buyers

Approval does not establish UK entitlement, free usage, client-facing productization permission or independent safety. Identity readiness and retention determine deployment fit.

What buyers should do

Confirm the target scope, account route and retention; prepare phishing-resistant MFA and short-lived credentials, then run a bounded authorised pilot.

Primary announcement

Anthropic expanded Cyber Verification Program — 6 October 2026 ↗

This is a dated source-linked buyer briefing. A vendor announcement does not prove UK account eligibility, an independent performance result or regulatory compliance. Open the primary source and confirm the exact plan before changing a production workflow.
