How can we help?►►

If you need something secure, consider it done.

To defend your organization's digital turf, you need a zero trust model that secures every access attempt and authenticates every identity. At the same time, you need to frustrate attackers — not users. This is where Duo comes in.

Five key ways Duo keeps your business safe and secure

  1. Phishing-Resistant MFA

    Duo enables you to verify user identity at login with two or more authentication methods, so you can guard against modern phishing attacks.

  2. Trusted Endpoints

    Duo makes it easy for you to define and manage trusted endpoints by ensuring that only known devices can access your organization's applications.

  3. Adaptive Access Policies

    Duo gives you control over who can access what and when. Simply apply custom policies based on role, device, and location.

  4. Passwordless

    Duo reduces the risk and administrative burden of passwords by letting users log in using biometrics, security keys, and more.

  5. Risk-Based Authentication

    Duo gives you peace of mind by automatically detecting and mitigating potential threats at each login attempt.
