Duo Security
Multi-factor authentication for secure access to applications
What Duo Security does
Duo Security is an identity and access management platform focused on providing multi-factor authentication (MFA) as part of a zero trust security approach. Founded as an independent company and now part of Cisco, Duo Security is widely used to help organisations confirm user identities before granting access to internal and external applications. It works by requiring a second verification step, such as a mobile notification or code, alongside a standard password.
The platform is positioned for businesses looking to strengthen login security and reduce the risk of unauthorised access. Duo is recognised in the security industry for its focus on usability and support for a broad range of applications and devices, though its feature set and integration depth depend on the chosen tier.
What sets it apart
Duo stands out for its accessible MFA and strong integration with Cisco's wider security suite.
