End-to-End Phishing Resistance
Attackers are increasingly bypassing basic MFA by using phishing techniques. Duo takes an end-to-end, easy-to-deploy approach to phishing resistance, protecting users at every step while helping IT teams of all sizes secure their organizations without increasing their workload.

Phishing evolves. Duo outpaces it.
Phishing protection should not stop at login. Duo helps go beyond basic MFA and SSO to secure every stage of the authentication. By extending trust behind the scenes, Duo offers stronger security without making your jobs harder.

Unleash Phishing-Resistant MFA
Protecting against modern phishing attacks has proven challenging. This is why Duo built the only phishing-resistant MFA that is easy to deploy. Using a mobile phone to verify the legitimate user is near the device requesting access, Duo eliminates the need for hardware tokens and complex configurations. It’s simple, seamless, and highly secure.

Ditch passwords for good
Attackers love passwords. That’s why Duo is committed to eliminating passwords entirely, even at the most challenging stages like enrollment and fallback. Duo's complete Passwordless solution makes it nearly impossible for attackers to gain access.

Stop session hijacking
Session hijacking, stealing an authenticated session to bypass MFA entirely, is on the rise. Duo’s patent-pending technology defends against this advanced technique by securing not just the login but the session itself. This is a crucial layer of protection that most other solutions overlook.

‘End-to-end’ phishing-resistance made easy
Attackers are more sophisticated than ever. They are increasingly bypassing traditional MFA. To outsmart them, Duo makes it easy to deploy phishing-resistant authentication, end-to-end.
How Duo delivers end-to-end phishing resistance
The simplest way to achieve phishing-resistant authentication
Stop remote attackers before they succeed. Duo Proximity Verification leverages the user’s phone as proof of proximity to the device requesting access, just like a hardware key does. By ensuring the legitimate user is behind the login, Duo delivers strong protection without extra hardware or complexity.
Complete passwordless
Duo unlocks the path to a true Passwordless world by removing passwords from every step of the authentication process, from setup, OS login, application login, even at the most challenging stages like enrollment and fallback.
Leave nothing to steal
Attackers steal session cookies to hijack access that's already established. Duo Passport with Session Theft Protection removes cookies from the authentication flow, leaving attackers with nothing to steal. Duo’s cookie-less solution provides a balanced approach to security while preserving the end-user experience.
Verify the device, not just the user
Knowing which devices connect, including personal ones, helps stop phishing. Devices that meet security requirements reduce risk and leave fewer gaps for attackers.
Protect the help desk from phishing
Phishing threats now include deepfakes and fake executive requests aimed at the help desk. Duo delivers end-to-end phishing resistance with Help Desk Push and Cisco Identity Intelligence. These tools help verify users quickly without slowing things down or sacrificing support.
