Duo Security

An Overview of Duo Security

What is Duo Security?

Duo Security is a cybersecurity company that provides user authentication and access management solutions for organizations. Founded in 2009, Duo Security aims to protect businesses from data breaches by verifying user identities.

The company’s flagship product is the Duo Beyond platform, which offers multi-factor authentication (MFA), single sign-on (SSO), and adaptive access controls. Duo Beyond integrates with hundreds of applications and devices to add an extra layer of security beyond just a password.

How Does Duo Security Work?

Duo Security utilizes a two-factor authentication system to verify a user’s identity. When logging into an application protected by Duo, users will:

1. Enter their username and password as usual. This is the first “factor” of authentication.

2. Be prompted to confirm their identity through a second factor. This could involve entering a passcode sent via SMS or generated by an authenticator app, receiving a phone call, using biometrics like fingerprint or face ID, or tapping “Approve” on a paired mobile device.

By requiring two forms of authentication, Duo makes it much harder for hackers to access accounts even if they steal someone’s password. Duo’s approach helps defend against phishing, credential stuffing, and password spraying attacks.

Duo Security Features

Some key features of Duo Beyond include:

– Multi-factor authentication (MFA) – Adds an extra layer of verification such as a one-time passcode. Prevents unauthorized access.

– Single sign-on (SSO) – Allows users to access all their applications with one set of credentials. Reduces password fatigue.

– Adaptive access controls – Uses contextual data like IP address, geographic location, and device posture to identify risky logins and prompt for MFA.

– Device trust – Grants full access to users on trusted devices without prompting for MFA each time.

– Active Directory integration – Syncs and authenticates against Active Directory in real time.

– Detailed reporting – Provides visibility into user access, compromised accounts, blocked logins, and more.
