Duo Security (with AI)

Preview

Duo Security, part of Cisco, is a leading provider of multi-factor authentication (MFA) and secure access solutions. Founded in 2010, the Duo platform significantly enhances account and data security by requiring a second verification step during login, in addition to a password. This can involve confirmation via the Duo Push mobile app, entering an SMS code, or using other methods. A key aspect of Duo is its leverage of artificial intelligence and machine learning, particularly in its adaptive and risk-based authentication features. The system analyzes various signals, including user behavior, information about the device being used (its status, updates, security posture), and the access context, to assess the risk level of each login attempt. Based on the risk assessment, Duo can dynamically alter authentication requirements, requesting additional verification when suspicious activity is detected or access is attempted from an untrusted device. This ensures strong protection without unnecessarily burdening users during typical access scenarios. Duo supports a wide range of integrations with enterprise applications, VPNs, cloud services, and other security tools, simplifying deployment and enabling consistent access policies. The platform is available for various operating systems for the authentication proxy and via a web interface, and it also has a mobile application for users. Duo Security plays a vital role in implementing Zero Trust security strategies, helping organizations verify every user and device before granting access to resources, thereby reducing the attack surface and protecting against unauthorized access.
