30-day money-back guarantee on all paid plans.
Harvest now, decrypt later
The attack has already started. You just can't see it yet.
Adversaries are recording encrypted traffic today: your emails, logins, and private messages. They store it all. When a large enough quantum computer arrives, today’s encryption falls, and every record they kept becomes readable.
They record everything
Your encrypted data is copied and archived in bulk. Classical encryption looks safe, for now.
Quantum arrives
A cryptographically-relevant quantum computer breaks RSA and elliptic-curve encryption in hours, not millennia.
Nothing to break
Secria wraps every layer in NIST-standardized post-quantum cryptography today. There’s no classical-only record to come back for.
Don’t take our word for it.
Privacy you can verify, not just trust. Named cryptographic standards and a zero-knowledge architecture keep your keys out of our reach, even under legal compulsion.

The Secria ecosystem
Two products. One private ecosystem.
Your traffic is being recorded today to be decrypted by quantum computers tomorrow. Secria stops that, at every layer.
Secria Mail
Post-quantum encrypted email with zero-knowledge architecture. Phishing and spam protection, sender verification, and aliases, built in.
- ML-KEM-1024 hybrid post-quantum encryption
- Zero-knowledge: we can't read your mail
- Anti-phishing, spam filtering, and aliases
- Available on iOS, Android, and the web
Secria VPN
The same post-quantum protection, now for your whole connection. Quantum-safe WireGuard, RAM-only servers, and zero logging.
- Post-quantum WireGuard at every layer
- RAM-only servers, nothing written to disk
- Zero logging and multi-hop routing
- Bundled with your Secria account
Get both. One account, one price.
Secria Pro bundles post-quantum Mail and the full VPN, often cheaper than a standalone VPN alone.
