title: "Developing Enterprise Frontier Safeguards with our customers"
description: "Anthropic is announcing Enterprise Frontier Safeguards (EFS), designed to combine zero data retention (ZDR) with monitoring for serious misuse of frontier models. The service addresses enterprise concerns that detecting activity such as fraud, cyberattacks, or biological capability development, or stolen credentials, may require retaining and correlating traffic across sessions and accounts, while regulated organizations may not accept provider-held data or human review. EFS stores activity data in customer-controlled cloud infrastructure, under customer-managed encryption keys, access policies, and audit logging, while automated systems analyze a rolling traffic window and send flags directly to the customer for review. It will roll out in phases later this fall, support Anthropic and partner cloud offerings, and let customers opt into storage, encryption keys, and automated review without changing model behavior, pricing, or rate limits."

# Developing Enterprise Frontier Safeguards with our customers

**Type:** Announcement

## Summary

Anthropic is announcing Enterprise Frontier Safeguards (EFS), designed to combine zero data retention (ZDR) with monitoring for serious misuse of frontier models. The service addresses enterprise concerns that detecting activity such as fraud, cyberattacks, or biological capability development, or stolen credentials, may require retaining and correlating traffic across sessions and accounts, while regulated organizations may not accept provider-held data or human review. EFS stores activity data in customer-controlled cloud infrastructure, under customer-managed encryption keys, access policies, and audit logging, while automated systems analyze a rolling traffic window and send flags directly to the customer for review. It will roll out in phases later this fall, support Anthropic and partner cloud offerings, and let customers opt into storage, encryption keys, and automated review without changing model behavior, pricing, or rate limits.

## Context

Enterprises need to detect sophisticated misuse that can span multiple sessions and accounts, but many regulated organizations find provider-held data retention and provider personnel reviewing sensitive information difficult to use. The stated goal is to combine the safety value of monitoring with the privacy and control of zero data retention.

## Approach / What changed

EFS stores monitoring data in a customer-controlled cloud account under customer-managed encryption keys, access policies, and audit logging. Automated systems analyze a rolling window of traffic for serious-misuse signals and send flags directly to the customer, with no Anthropic human review required. Customer-owned storage, managed keys, and automated review are opt-in controls.

## Takeaways

- EFS can store activity data in customer cloud environments such as Amazon S3, Azure Blob Storage, or Google Cloud Storage, with customers retaining control of storage and management.
- Automated monitoring correlates traffic across time and accounts to detect signals including offensive cyber or biological capability development and stolen or leaked credentials; resulting flags go to the customer.
- The controls are intended to work across Anthropic access and cloud-partner offerings, carry no Anthropic charge, and do not change model behavior, API pricing, or rate limits.
