On 2026-09-01, Anthropic announced "Enterprise Frontier Safeguards (EFS)," a new security feature that balances the protection of corporate confidential information with the detection of misuse. EFS aims to combine a privacy-focused mechanism that does not retain data with the ability to detect fraudulent patterns across multiple sessions. For monitoring activity data, options are provided so that customers can manage it using their own cloud environments and encryption keys. Furthermore, the system is designed to send notifications to the customer when an issue is detected via automated monitoring, providing a mechanism that does not require data verification by external parties. The company stated that it is developing the feature in collaboration with more than 100 customers and plans to begin a phased rollout starting in late autumn 2026.
