Features

Cirrus Files is built around three ideas: your data is yours, transfers should be fast, and admins should see everything that happens.

End-to-end encryption

Files are encrypted on your device with AES-256-GCM before they leave it. Keys never touch our servers.

Secure sharing links

Expiring links, passwords, download limits and per-recipient access logs for every share.

Fast, resumable sync

Chunked parallel transfers saturate your uplink and resume exactly where a dropped connection stopped.

Version history

Restore any file to any point in the last 180 days. Ransomware-proof snapshots on Business plans.

EU data residency

Primary storage in Frankfurt with replication to Amsterdam. Your data stays where you put it.

SSO and audit

SAML SSO, SCIM provisioning and an immutable audit log that exports to your SIEM.

Built for pipelines, too

Every feature is available over a documented REST API and an S3-compatible endpoint, so CI jobs, backup tools and scripts can use the same storage as your people.
