Duo is a security platform that verifies user identities, enforces access controls, and provides multi-factor authentication to protect organizational applications and data from unauthorized access.
Duo is a cloud-based access security platform designed to protect organizations from identity-based threats and unauthorized access. It provides multi-factor authentication (MFA), device visibility, and adaptive access controls to ensure that only trusted users and secure devices can reach corporate applications and data. Duo’s primary purpose is to strengthen authentication, reduce the risk of account takeover, and support a zero-trust security model across modern, hybrid, and remote environments.
Duo offers phishing-resistant MFA options, including WebAuthn/FIDO2 security keys and platform authenticators, alongside more traditional methods such as push notifications, SMS, and phone callbacks. Its device trust capabilities assess the security posture of endpoints—checking OS versions, disk encryption, and other security controls—before granting access, without requiring a full device management solution. Duo’s policy engine enables granular, context-aware access rules based on user role, device health, location, and network, helping organizations enforce least-privilege and step-up authentication. Centralized dashboards, detailed logs, and integrations with SIEM and identity providers (such as Azure AD, Okta, and on-prem directories) support monitoring, compliance, and incident response.
