Anthropic announces Enterprise Frontier Safeguards (EFS), a solution that combines zero data retention (ZDR) with state-of-the-art misuse detection safeguards. EFS stores data in customer-controlled cloud infrastructure, not Anthropic. Developed with over 100 customers, it will roll out in phases starting later this fall. Eligible customers receive ZDR on Fable 5 and Fable 5.1 until EFS is ready.
