Anthropic moves misuse monitoring into customer clouds
Anthropic announced Enterprise Frontier Safeguards, which keeps the safety monitoring data behind its 30-day retention policy inside customers' own cloud accounts, removing a blocker that has kept regulated industries off retention-based deployments.
Anthropic said Enterprise Frontier Safeguards (EFS) pairs the privacy of zero data retention with the misuse detection that retention enables, by storing activity data in cloud infrastructure the customer controls rather than Anthropic's. Data used for monitoring can live in a customer's own Amazon S3, Azure Blob Storage, or Google Cloud Storage, under their encryption keys, access policies, and audit logging.
Monitoring is automated only. Systems analyze a rolling window of traffic for signals of serious misuse — including attempts to develop offensive cyber or biological capabilities, and signs of stolen or leaked credentials — and send flags directly to the customer. Anthropic says no human review by its employees is required.
The company framed EFS as a response to its own 30-day retention policy, introduced with Fable 5, which it says was needed because sophisticated misuse spans many sessions and accounts and cannot be caught by discarding each interaction immediately. Regulated customers found retention hard to adopt. Anthropic reiterated it has never trained on enterprise data without explicit permission.
Anthropic says it designed EFS with more than 100 customers spanning a quarter of the Fortune 100 and every US global systemically important bank, working with the Analysis and Resilience Center for Systemic Risk — whose members include CISOs at Goldman Sachs, Morgan Stanley, Citi, Bank of America and Wells Fargo — plus Comcast, KPMG, Mastercard, Salesforce and Visa, and cloud partners AWS, Google Cloud and Microsoft Azure.
EFS is not shipped. Rollout begins in phases "later this fall," with support planned for Claude Code, Claude Enterprise, the Claude Platform, Amazon Bedrock, Google's Agent Platform and Microsoft Foundry. Eligible customers get ZDR on Fable 5 and 5.1 in the interim. Anthropic did not disclose pricing or eligibility criteria.
