About Duo Security

Duo Security, now part of Cisco, provides multi-factor authentication (MFA) and zero-trust security solutions that verify user identities before granting access to applications and networks. It's used by organizations ranging from small businesses to large enterprises to protect against unauthorized access and credential-based attacks. The platform stands out for its user-friendly push notification authentication, broad device visibility, and straightforward deployment. Duo focuses on making security accessible without requiring deep technical expertise, which has made it one of the most widely adopted MFA solutions on the market.

About Auth0

Auth0 is an identity-as-a-service platform that handles authentication and authorization so developers don't have to build login systems from scratch. It supports a wide range of identity protocols including OAuth 2.0, OpenID Connect, and SAML, along with social logins, multi-factor authentication, and passwordless options. Acquired by Okta in 2021, it's particularly popular among developers for its extensive documentation, SDKs for nearly every major language and framework, and flexible extensibility through custom rules and actions. It serves everyone from startups needing a quick login solution to enterprises managing complex identity requirements across multiple applications.
