Product

Checks every email. Keeps none of them.

Ṣọ checks every email for fake senders, harmful links and risky attachments, and tells you in plain words why a message looks wrong. Emails are checked on our servers and never stored.

Details

One security layer across browser, Mac, and mobile

The browser extension, the Mac app, and the mobile apps are all available today. Same policies on every one, and nothing new for your team to learn.

Explainable AI detection

  • - Plain-language explanations, not vague threat scores or red/yellow labels.
  • - The sender, the links and the attachments are checked together, not one at a time.
  • - No training modules or IT setup. Protection works from the first email.

Privacy-first architecture

  • - Emails analyzed on our secure servers. Never stored. Zero retention.
  • - No cloud proxying, no MX record changes, no DNS rerouting.
  • - We never sell your data or use your email to train models.
