# Storage Buckets: Security & Compliance

Storage Buckets are built on the same infrastructure that powers the Hugging Face Hub, with enterprise-grade security and compliance built in.

## Encryption

All data stored in buckets is encrypted at rest using **AES-256** encryption. Data in transit is protected via **TLS**.

## Access Control

Buckets use the Hub's standard access control mechanisms:

- **SSO**: Authenticate through your organization's identity provider via [Single Sign-On](./security-sso)
- **RBAC**: Fine-grained permissions through [Resource Groups](./security-resource-groups) let you control who can read, write, or admin each bucket
- **Tokens**: Programmatic access is managed through [User Access Tokens](./security-tokens) with scoped permissions

## Audit Logs

All bucket operations — uploads, downloads, deletions, and permission changes — are recorded in your organization's [Audit Logs](./audit-logs), giving you a full trail of who accessed what and when.

## Data Residency

Bucket data is stored in **US and EU regions**. You can choose where your data lives when creating a bucket, and [pre-warming](./storage-buckets#pre-warming-and-cdn) lets you cache data closer to your compute in specific cloud regions.

## Compliance

Hugging Face maintains the following certifications and compliance standards:

- **SOC 2 Type 2** certified — active monitoring and patching of security vulnerabilities
- **GDPR** compliant — data processing agreements available through [Enterprise Plans](https://huggingface.co/pricing)
