How it works

Simple to explain. Simple to run.

  1. Keep what works

    Your mailboxes and email clients stay as they are.

  2. Add a gateway you own

    Filter inbound mail and encrypt stored messages on your host.

  3. Protect sensitive sends

    With Professional, matching outbound mail goes to the portal instead of the inbox.

Trust & security

Clear about what it does and doesn't.

Self-hosted

The gateway runs on a Debian host you control. Nothing in the mail path depends on Rubix.

Your keys

Stored messages are encrypted at rest with a key generated on your host. It never leaves it.

Fair comparisons

Our comparison pages cite sources and dates, and say where a hosted service may suit you better.

Quick answers

Before you ask

How is this different from a hosted encryption service?

Hosted services run the encryption and storage on their infrastructure. Secure Message runs on yours, with the key on your host. If you'd rather not run a server, a hosted service may be the better fit, or ask about managed hosting by request.

Do recipients need to install anything?

No. They open a link and enter a one-time code sent to their inbox. The portal is a Professional feature.

Can we try it free?

Yes. Community is free for one domain and one administrator, and covers inbound filtering.
