Verify user trust. Duo uses a second form of validation, such as a smartphone, to verify that a user is who they say they are before granting them access.

Establish device trust. Once access is granted, Duo enables your organization to see every device that is connected to your network and applications and easily monitor device health and compliance.

Enforce adaptive policies. You can set access levels based on role, device, location, and other relevant factors.

Grant secure access to users. Get even more secure access, beyond what a VPN can provide, and verify the identities of users from wherever they choose to log in.

Grant secure access to apps. Provide users with single sign-on (SSO) for a consistently easy login experience. A user-friendly dashboard provides streamlined access to company apps.

Passwordless authentication: Passwordless authentication is the term used to describe a group of identity verification methods that don't rely on passwords. Examples of passwordless authentication include biometrics, security keys, and specialized mobile apps.

Two-factor authentication: Two-factor authentication adds a layer of security to online accounts using a second device such as a smartphone. By sending a push notification to that device, two-factor authentication prevents another person from accessing an account—even if the password has been compromised.

Zero trust: Zero-trust security can be summarized as "never trust, always verify." Traditional security strategies operate under the assumption that any user or device within a corporate network can be trusted. With so many users now logging in remotely, this approach is no longer viable. Data and applications aren't located behind the network perimeter and a firewall, and users connect directly to company networks with personal devices.
