Two-Factor for All: Duo Editions Designed for Every Need

Stolen credentials are the frequent culprit of data breaches, bringing into focus the inability of a password alone to protect user accounts. A few decades ago, strong passwords were a sound method of verifying identity. Today, attackers can use malware to steal your passwords, take advantage of GPUs to crack passwords in just a few hours, or social engineer a password out of an unsuspecting user.

While two-factor authentication has typically been limited to use by large businesses, it’s now more attainable than ever with Duo. Our cloud-based service eliminates the need for on-premise hardware or software installs, allowing for the ease of integrating two-factor with your existing applications in minutes, not days.

Our mission at Duo has always been to provide world-class security to everyone—without compromising usability. With that in mind, we’re officially launching two revamped editions of Duo today, while keeping our free-for-life Personal Edition available to all users.

Duo’s Business Edition is designed to provide affordable security for small and mid-sized businesses on a budget, at just $1/user/month, including:

  • Our patented, streamlined cloud deployment.
  • Support for any authentication method, from Duo Push on a mobile phone, to SMS and voice, to hardware tokens.
  • Easy integration with hundreds of applications, including Microsoft’s Outlook Web Access; Cisco, Juniper, F5, Palo Alto, and Barracuda VPNs; and SSH.
  • Terrific support via chat and email.

In addition to our Business Edition, we’re announcing Duo’s Enterprise Edition with advanced management features for larger and more sophisticated deployments, including:

  • Microsoft Active Directory (AD) synchronization allows for rapid provisioning and deprovisioning by administrators.
  • Seamless integration capabilities with support for Microsoft Active Directory Federation (ADFS) and Remote Desktop Services (RDS).
  • Groups management controls allow admins to organize and assign user access with ease.
  • Powerful login controls, including the ability to define trusted networks and devices.
  • Comprehensive API access that empowers developers to build enhanced two-factor authentication solutions that fit their organization’s unique requirements.
  • Premium support that includes 24x7 response for critical issues via phone, chat or email.
