Encryption with keys that never leave the owner
Protect data in transit and at rest with keys created and controlled by the data owner — not a third-party vendor
Most solutions protect data only while it moves. Faction protects it in transit and at rest, with keys created and held by the owner — so data isn't left decrypted on cloud servers and endpoints waiting for the next breach.
Keys are generated on your own device and never transmitted to Faction. There is no master key. Faction's infrastructure routes your encrypted traffic but cannot read your content — it is technically incapable of doing so, even if compelled. That's Zero Knowledge as a property of the architecture, not a promise in a policy.
Encrypted email
Sign and encrypt mail in the client you already use — S/MIME, with your own certificate. No new tools.
Secure file transfer
Send files of any size directly between devices; they never touch Faction's infrastructure.
Encrypted at rest
Files stay encrypted on your endpoints and in storage, under keys only your devices hold.
Owner-held keys
Keys are generated on your device and never leave it — Zero Knowledge, so Faction can't read what you protect.

Use your own email
Keep the email app you already use, but encrypt message contents with a personal X.509 certificate signed by your own key.
Bring your own cloud drive
Store and share on the cloud drive you prefer — encrypted with your own keys, with no cloud exposure of the contents.
Share files anywhere
Move files of any size across platforms through your own distributed network of drives and devices.
Owner-keyed at rest
Data stays encrypted on endpoints and in storage; the keys never leave the owner's devices.
- API communication — RSA-4096 with AES-256-GCM and Ed25519 secures traffic between your device and Faction's infrastructure.
- Network transport — WireGuard (ChaCha20-Poly1305) encrypts everything moving across your private circuit.
- Peer-to-peer — mutual TLS 1.3 with X.509 certificates protects direct device-to-device sessions, including file transfers.
- Data at rest — AES-256 keeps stored data encrypted on your endpoints and in backup, under keys only your device holds.
Own your trust. Keep your peace of mind.
The new threat environment calls for a new Zero Trust model. We'd welcome the chance to show you how Faction puts you in control and secures your critical systems and assets rapidly with low cost and IT overhead.
