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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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.

    I began using it for my university login. It was easy to set up and utilize on an on-going basis. I now use it for my OneLogin as well.

    Pros

    Super easy to set up a new two-factor authentication, which I cannot say the same for some of the other ones that I have used.

    Cons

    No cons for two-factor authentication. It was super easy to set up new ones, and I use Duo whenever it is available for two-factor requirements.

    Duo Security is great at multi-factor authentication

    Reviewed on 31/8/2022

    Pros

    I liked that it connected to my phone and it was easy to get the passwords and respond to the notification to sign in. I liked that my organization valued my security and was investing in products to keep me and my data safe

    Cons

    It took some time to adjust to this software but that was because it was the first multi-factor authentication that I used. Now that it has been a few years, I am fully on board and don't find it inconvenient anymore

    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.
