Attackers hate us. Users love us.

Easy to use. Incredibly effective. Cisco Duo simplifies access management for your workplace. We've got you.

One of the world’s most trusted access management tools

From start-ups to large enterprises, companies of all sizes depend on Cisco Duo to prevent unauthorized access.

The gold standard in MFA

Stay protected with flexible Multi-Factor Authentication (MFA) including options using FIDO2 for phishing-resistant authentication — hook, line, and no sinker.

Get picky with permissions

Customize who gets access to what and when it's allowed. With adaptive access, you can quickly define granular permissions based on role, location, and device.

No device left behind

Keep your circle tight. Verify the trustworthiness of every device that tries to access your applications while simultaneously tracking their health status.

One login to rule them all

Minimize your attack surface with Single Sign-On (SSO) while reducing IT costs and providing one easy, consistent login experience for all applications.

Anyone, anywhere, any device
