Privacy meets safety monitoring

Anthropic launches Enterprise Frontier Safeguards, combining zero data retention privacy with misuse detection. Data stays in customer-controlled cloud infrastructure.

Built with 100+ companies

Anthropic developed EFS with over 100 customers across financial services, healthcare, manufacturing, telecom, law, retail, and public sector.

Rolling out this fall

EFS launches in phases starting later this fall. Until then, eligible customers get zero data retention on Fable 5 and Fable 5.1.

More powerful, more risk

Mythos-class models like Claude Fable 5.1 bring major intelligence gains but also potential for misuse and autonomous misbehavior.

Sophisticated attacks need monitoring

Anthropic has seen attempted misuse ranging from fraud to cyberattacks. Some involve stolen credentials that spread across multiple sessions and accounts.

Why 30-day retention started

Detecting sophisticated misuse requires storing data to correlate patterns across time and accounts. That's why Anthropic introduced 30-day retention with Fable 5.

“This policy was not motivated by a desire to train on enterprise data: Anthropic has never trained on enterprise data without explicit permission, and never will.”

Regulated industries pushed back

Enterprises understood the security value of data retention but many in regulated industries couldn't use models that retained their data.

Banks helped design the solution

Anthropic worked with ARC, whose members include CISOs from Goldman Sachs, Morgan Stanley, Citi, Bank of America, and Wells Fargo.

Fortune 100 feedback shaped it

Anthropic consulted a quarter of the Fortune 100, every US global systemically important bank, and virtually every regulated industry.

Customers control the reviews

When automated monitoring detects suspicious patterns, signals go directly to customers. They review what the systems found, not Anthropic.

Data lives in customer clouds

Activity data used for monitoring can be stored in the customer's own cloud account, like Amazon S3, Azure Blob Storage, or Google Cloud Storage.

No Anthropic human review required

Automated systems analyze traffic for serious misuse signals, including cyber or biological threats and stolen credentials. Flags go straight to customers.

Wells Fargo keeps full custody

Wells Fargo says their logs stay in their environment under their keys. They keep data custody while Anthropic operates detection.

“Enterprise Frontier Safeguards gives us exactly what we asked for: our logs stay in a Wells-managed environment under Wells-managed keys.”

Banks set the requirements

Eight ARC members worked with Anthropic to define what it takes to run frontier models inside systemically important banks.

Opens up regulated workloads

The safeguards let companies apply AI in parts of the business they couldn't before, where work is regulated and highly sensitive.

Works across all platforms

EFS controls work the same whether you access Claude directly from Anthropic or through AWS, Google Cloud, or Microsoft Azure.

No extra charge from Anthropic

Anthropic doesn't charge for Enterprise Frontier Safeguards. Customers only pay their cloud provider for storage and data transfer.
