## 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.
## Key takeaway

Anthropic's new Enterprise Frontier Safeguards lets companies keep AI conversation data in their own cloud infrastructure while automated systems monitor for misuse.
