+Cellar provides enterprise-grade security for your object storage through multiple layers of protection, from access control to data encryption.
+
+## Security on Cellar
+
+### Access Control
+
+You can control who can access your Cellar buckets and objects using Access Control Lists (ACLs). You can grant or restrict permissions at both the bucket and object level, allowing you to:
+- Define read and write permissions for specific users or groups
+- Set public or private access policies
+
+### Pre-signed URLs
+
+You can generate temporary, secure URLs for uploading or downloading objects without exposing your credentials. Pre-signed URLs include:
+- Time-limited access that expires automatically
+- Cryptographic signatures that prevent tampering
+- Granular permissions for specific operations (upload or download)
+
+### Data Protection
+
+All data transmitted between your applications and the storage service can encrypted using the TLS protocol. 
+
+### High Availability and Durability
+
+Cellar's architecture, built on Ceph, ensures data remains available and protected against loss:
+- **Sharding**: Data is distributed across multiple storage nodes to balance load and improve performance
+- **Multi-DC replication**: Every object is replicated across our 3 geographically distinct Paris datacenters
