Two-factor authentication for everybody.

Price should no longer be the main factor.

Two-factor authentication has been typically limited to larger size businesses with the resources to support it, but Duo's variable cost subscription pricing (as-a-service) enables strong authentication to be effectively applied to every business, regardless of size and complexity. You only pay for what you need.

No infrastructure required, now or later.

Your users can bring their own devices, which means no hardware investment for you. And our multi-tenant cloud architecture allows you to scale from one to millions of users, with no additional hardware or user training.

From evaluation to solution in minutes — not months.

Easily provision hundreds of thousands of users, or let them do it themselves.

Secure users easily with rapid user provisioning via Active Directory synchronization and bulk user imports with CSV files. For smaller deployments, users can also simply provision themselves using our self-enrollment feature.
