What you can do with Octet

Octet builds up where a user really is from signals it checks, not from trusting the IP address or what the device reports, and signs the answer.

  1. Geofence without destroying the experience.

    Determine a user’s country in the browser, without a permission prompt. Their VPN can stay on.

    Explore country checks →

  2. Guarantee the location.

    When being there is non-negotiable, require proof. The phone proves where it is. You verify that proof offline.

  3. Make bots and rogue agents prohibitively expensive.

    Require a real phone and human approval from an approved location for every account. A bot farm now has to pay for the phones, pay the people operating them, and get both into approved locations.

  4. Turn plain language into enforceable physical rules.

    Combine provable location with identity, permissions and approvals. Describe your rules in plain language. Octet makes them enforceable in your application. With one prompt, move a rule from a country down to a single building.
