Trusted Access through Duo and CTI

Duo ensures only Trusted Users and Trusted Devices can access Every Application.

Duo’s Trusted Access platform is a holistic security solution that reduces your risk of a data breach caused by compromised credentials, known vulnerabilities and/or exploits.

Using two-factor authentication, Duo verifies your users’ identities. Then, Duo checks your users’ devices for out-of-date software, missing security features and certificates, enabling you to enforce device access policies to block any risky or untrusted devices.

Finally, Duo grants your users access to only the applications you want them to access, while giving them simplified access to their on-premises and cloud applications with secure single sign-on.

Our Mission is to Protect Your Mission.

You have your own mission to fulfill — and managing security shouldn’t stand in your way. Put your passion into your business, and trust the experts at Duo to secure it.

We’re more than a security company. We’re a Trusted Access company.
