Multi-Factor Authentication (MFA): Verify the identity of all users with Duo's strong two-factor authentication.
Make sure your users are who they say they are. Verify users' identities with Duo's strong two-factor authentication - before granting access to applications - to protect against phishing and other access threats. This is the first step toward a zero-trust security platform.

Device Trust: Check that your users' devices meet your security standards before granting them access.
After verifying user identities, Duo checks that their devices meet your security standards - safeguarding against vulnerable or compromised endpoints. Regain insight and control over managed and unmanaged devices, before they access your applications.

Adaptive Authentication & Policy Enforcement: Set policies to grant or block access attempts by user or device, based on contextual factors.
Want to grant access based on specific users or groups? How about by geolocation? Duo lets you set and enforce fine-grained policies to grant or block access attempts based on a user’s role, device hygiene, location, network and a host of other contextual factors.

Remote Access & Single Sign-On: Seamless and secure access to cloud and on-premises applications and servers.
Secure access boils down to one main goal: protect every application, whether it’s in the cloud or on-premises. With Duo’s remote access and single sign-on (SSO) you give your users secure access to all business applications, from any device and any location.
