Upgrade your security, lower your costs

Duo vs. Traditional Two‑Factor

Technology has evolved. But old two-factor solutions have not - they were created for the client-server computing model of the 1980s-90s. With that comes a long list of upfront hardware, software, installation, maintenance and management costs.

But technology has evolved over the past twenty to thirty years, meaning new security threats have evolved too.

Secure by Design

Built-in security, modern technology.

Some two-factor solutions rely on shared secrets to generate token numbers, which attackers can steal and use to compromise organizations. Duo’s solution uses asymmetric cryptography, keeping only the public key on our servers and storing private keys on your users’ devices in a tamper-proof secure element. Duo never stores your passwords - meaning your logins stay safe. Learn more about Duo’s Security and Reliability.

Plus, our frequent product updates means you’re always protected against the latest vulnerabilities, while other vendors may only update every six months.

Advanced Endpoint Security

Complete protection with Duo’s Trusted Access platform.

Evolving security threats require more than just two-factor authentication. For complete protection, Duo’s Trusted Access platform checks the security health of every device before granting them access to your applications. Admins can set policies to block users based on software versions, user location, network type and more to reduce exposure to risky devices.

Finally, Duo’s single sign-on (SSO) integrates security with the ease of logging in just once to access multiple cloud applications, letting you consolidate your authentication and identity solutions into one.

The Most Loved Company in Security

But don’t just take our word for it. Thousands of organizations worldwide trust Duo.

  • “The transition away from RSA has been very simple,” he said. “We’ve actually had people proactively shipping back their tokens. Duo is a great product with great service. That’s hard to come by these days.”

    — Norman Bower, Information Security Engineer, Corporation Service Company
  • “The process of applying Duo’s 2FA service was easily applied not only for our developers but also our daily administrators that are creating new user accounts for our partners. The ease of use, service flexibility, and responsiveness of their support team made a big difference in making our application that relies on 2FA successful.”

    — Julie Dunn, NCFTA Team Lead, NCFTA
  • I haven’t gotten a single complaint about it. Our overall experience with Duo has been extremely easy - that’s not something that always happens in the technology world.

    — Tristan Hammond, IT Infrastructure Manager, Threadless
  • Facebook is a very fast-paced environment and we needed technologies that would allow us to maintain that pace. Because of the ease of use of Duo Security and Yubico authentication technologies, we have seen minimal support and overhead costs. Other technologies didn’t fully support our need to allow multiple and rapid logins to SSH sessions.

    — John “Four” Flynn, Information Security Manager, Facebook
