Last updated 3 months ago [Visit site](https://duo.com) Quick answer ## What is Duo Security? Short answer Duo Security, part of Cisco, is one of the most widely deployed MFA and zero trust access platforms. It is best known for push-based MFA, device posture checks and easy integration with existing SSO and VPN stacks. Duo is often used alongside a workforce IAM (Okta, Entra, Ping) to add strong authentication, device trust and remote access policy enforcement, rather than as the primary identity provider. Best for Enterprises and mid-market organizations that need strong MFA, device trust and zero trust access alongside an existing IdP. When to choose You need best-in-class MFA and device trust layered on an existing identity provider, with a path toward passwordless and zero trust. When not to choose You want a primary IdP, CIAM or a low-cost MFA bundled inside a broader productivity suite.
