Anthropic lets enterprises keep Claude safety logs in-house

Anthropic announced Enterprise Frontier Safeguards on September 1, 2026, a setup that stores activity data used for misuse detection in the customer's own Amazon S3, Azure Blob Storage, or Google Cloud Storage account under the customer's encryption keys, so Anthropic employees do not read the logs. The company developed the product with more than 100 customers after dropping zero data retention on its most capable models, will roll it out in phases with broad availability targeted for later this fall, and will give eligible customers zero data retention on Fable 5 and Fable 5.1 until their turn comes.
