Protect your VPN

Protecting remote access with two-factor authentication is the best way to protect your organization against phishing attacks, account takeover, and data theft. Duo Security allows you to easily deploy strong and effective two-factor authentication on your VPN. By taking advantage of users’ existing devices — their mobile phones — Duo efficiently and cost-effectively protects your organization from today’s threats.

Seamless Integration

Duo’s self-enrollment and login prompts are displayed inline on your VPN’s web login page after the user completes primary authentication. This ensures a consistent experience for your users, and reduces both training time and support costs.

Duo Security supports diverse user bases by allowing users to authenticate with whatever method is best for them. Some users will prefer the Duo Mobile app while others would rather carry a hardware token. Users can enroll multiple phones, a phone and a hardware token, etc.

Rapid Deployment

It takes less than 15 minutes to configure Duo Security on your SSL VPN. There’s no hardware to manage or software to install — just upload a customized template package and change your VPN’s settings. Your users are led through the self-enrollment process the first time they log in, registering their phones and (optionally) installing the Duo Mobile application on their smartphones.

Duo Security Offers Two-factor Authentication for Juniper, Cisco, Array, Palo Alto, F5 FirePass, SonicWALL, Citrix, Barracuda, Fortinet, and OpenVPN

Works for Everyone

The Duo Mobile smartphone application is free and available on all major smartphone platforms, and lets users easily generate passcodes without the cost and hassle of hardware tokens. iPhone, Android, Blackberry, and Windows Phone users can use Duo Push which “pushes” login or transaction details to the phone, allowing for immediate, one-tap approval:

Older devices like cellphones and landlines are also fully supported. Duo can send passcodes via text message, or place a phone call — users just press a button on their keypad to authenticate.

Duo Security Offers Multiple Methods for Two-Factor Authentication

Duo also sells and supports hardware tokens for users who prefer them. Hardware tokens can be ordered from the Billing section of the administrative interface.
