Duo Security

User identity verification & device vulnerability discovery

About Duo Security

Duo Security is a cloud-based solution for user identity verification and device vulnerability assessment which offers multiple methods of two-factor authentication, configurable permissions and controls, endpoint visibility and remediation, Single Sign-On (SSO), and more. The Duo Trusted Access platform is designed to address possible security threats by verifying users’ identities and device health before they are allowed to connect to the organization’s applications.

Duo verifies users’ identities in a number of ways, using two-factor authentication methods including SMS passcodes, phone callbacks, hardware tokens, and one-tap authentication through push notifications from the Duo Mobile app. Administrators can configure and enforce custom access policies and controls, including blocking user logins from specific locations, such as countries the company does not do business in. Application-based controls can also be set up, allowing administrators to define different two-factor authentication requirements for access to specific systems, such as requiring two-factor authentication for every VPN login attempt, but only once a week for Outlook access.

Duo allows users to create an inventory of user devices and use this data to identify vulnerabilities posed by outdated operating systems, browsers, and Flash & Java plugins. Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or immediately blocked from accessing applications, with permissions reinstated after the browser or plugin has been updated. For organizations where certain applications have specific browser or Flash dependencies, self-remediation policies can be set up to notify only particular users of issues with specific plugins or browsers.

Duo’s Access Gateway offers a secure web portal to give Single Sign-On (SSO) access to employees who use 10 or more cloud applications. Applications are presented on a single page, giving users visibility into all available applications. Device security health checks are carried out every time a user accesses a cloud application, and user identity is verified without the need for them to re-authenticate each time they access an application.

Key benefits of Duo Security

  • Permissions and controls can be configured to prevent users logging in from high-risk countries, or those which the company does not do business in, and two-factor authentication requirements can be set on an app-specific basis.

  • Detailed data on users’ devices can be recorded, and vulnerabilities identified, including outdated operating systems, plugins, and browsers, with automatic notifications to users and the option to block access to applications until vulnerable devices are updated.

  • The Access Gateway offers Single Sign-On (SSO) for employees who user 10 or more cloud applications, while still assessing device health and checking users’ identities every time an application is accessed.

  • Staff, visitors, and contractors can be granted temporary access using bypass codes, with the ability to generate single, event, and time-based codes, which can be set to expire after a set number of uses or amount of time.

  • Stolen or lost authentication devices can be disabled and dissociated from their user, and re-enabled if found.

    The MFA champion

    Reviewed on 29/06/2022

    Pros

    The mobile app for Duo is extremely intuitive and easy to use. As we implemented the product in our organization we were impressed with how little hand-holding was required for our user-base to adapt to the new authentication workflow.

    Cons

    This is going to seem nitpicky, and it is, but when the mobile application was recently re-written the location of the "accept/allow" login button switched from one side of the screen to the other. Users who frequently use the app very likely denied their login inadvertently.

    Super easy to use mobile 2-factor authentication software

    I have been using it for over 2 years and have never had an issue. It is very easy to use.

    Pros

    The way it connects to Cisco AnyConnect VPN so that I can safely connect to my work's network. I don't have to worry that someone will get into their network via my account because Duo is tied to my cell phone. It's very easy to use, you just open the app, click the show button on the 6 digit code, and punch that into AnyConnect when you try to connect. They also have an apple watch app so that you can receive the notifications on your watch to log in.

    Cons

    No qualms. It does what it's supposed to and does it in the most lightweight and streamlined way possible.

    Overall, because of these two experiences. I am genuinely going to look into an alternative option and preferably leave Duo as a personal preference. I love how secure it is but it's not okay to have a safety exit that doesn't work - like come on?

    Pros

    No one will ever get in to your apps or info

    Cons

    If you need to get in, you won't be able to. I had a phone stolen, and then unfortunately lost not long after I got a new phone. I had my back up codes saved when when the first one was stolen - did not let me into any of my apps and the worst part is - they give you 8-10 codes to use for a 'back up'. When the first one was stolen, I was extra safe and careful and then I sadly lost that one and I could, once again, not get into a single app using my back up codes.

    Overall Duo has helped us improving device security and we were able to integrate with our Palo Alto Firewall devices and had pretty smooth experience.

    Pros

    This worked pretty smoothly, when logging in the security devices such as firewalls, with duo we made sure no unauthorized users is logging into the devices with Multi Factor Authentication mechanism. With duo we simply were able to compliance with Zero Trust Model, no unauthorized users can make the changes on the system.

    Cons

    They can work on their mobile application and make sure to improve the user experience, I feel bit delay while receiving the authentication request. Also on mobile app they can make it like only one finger touch is enough to authenticate the user. So less clicks can make the experience way better.

    My overall experience with Duo Security is very good. It helps my organisation to secure the company resources or data which I can access via my credentials by adding the real-time authentication system. It helps them to secure the data if their members credentials get compromised.

    Pros

    Multi-Factor Authentication is the best feature I like most. It makes my data or resources secure even if my credentials got compromised. Through their real-time authentication process, users can authenticate themselves from anywhere and then they can access their resources. It also helps an organisation secure its data or resources.

    Cons

    As of now, I don't have anything which I don't like about this software.
