Your Journey to Zero Trust Starts Here

Zero trust takes security beyond the corporate network perimeter, protecting your data at every access attempt, from any device, anywhere. It's the future of information security — and Duo is your rock-solid foundation.

Verify User Trust

Ensure users are who they say they are at every access attempt, and regularly reaffirm their trustworthiness.

Establish Device Trust

See every device used to access your applications, and continuously verify device health and security posture.

Enforce Adaptive Policies

Assign granular and contextual access policies, limiting exposure of your information to as few users and devices as possible.

Secure Access for Every User

Provide appropriate permissions for every user accessing any application, anytime and from anywhere.

Secure Access to Every Application

Reduce the risk of credential theft by enabling users to securely access their applications with a single username and password.

Secure your workforce with Duo's zero trust security platform:

Multi-Factor Authentication

MFA is the foundation for zero trust. Duo verifies that your users are who they say they are, before they access your data — and with multiple second-factor options, including one-touch Duo Push, users can easily authenticate in seconds.

Device Trust 

Monitor the health of every device across your organization in real-time, whether it's corporate-managed or not. With Duo's device trust features, you can customize access requirements at the device level, and because it's a cloud-based solution, you'll stay ahead of the latest security threats.

Adaptive Access Policies 

Grant your users just the right amount of access. Duo's advanced policy enforcement capabilities let you define security requirements at the user, device, and application level, based on contextual factors like location and update status.

Remote Access 

Enable your mobile workforce without compromising your company's data. Duo provides modern remote access solutions and protects existing IT infrastructure, making it easy to onboard new employees and contractors and allowing employees to work on the go.

Single Sign-On 

Duo's SSO grants users secure access to all protected applications (on-premises or cloud-based) through a uniform, frictionless interface that's accessible from anywhere.
