Why use Cyph?

Works In-Browser

Cyph is the only encryption app that is secure to use in a web browser, thanks to our patented WebSign technology. Every time you open Cyph, the integrity of the application is verified, ensuring it hasn’t been tampered with.

Secure Data Syncing

Securely sync all your encrypted data between all of your devices. Don’t be limited to one device or lose all your data if it’s lost, stolen, or destroyed. — Encrypted cloud storage

Auto ID Verification

Have you ever actually done an in-person fingerprint verification on another encryption app? It’s critical to the security, but the vast majority of people don’t! Cyph doesn’t require manual verification to protect against impersonation attacks. — Air gapped certificates

Quantum-Resistant

Cyph uses multiple quantum-resistant cyphers, which will protect your data long-term against future advancements in quantum computing. We are the only commercially available service that offers this protection. — Castle
