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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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

    An Extra Layer of Security

    Overall, it's been a great experience. We implemented it so that we could have unified MFA over multiple platforms--VMware and M365, for example. It also gives users who don't want to use an app on their phone the option of using a hardware key. Setup and integration isn't too rough and the support is excellent.

    Pros

    Being able to manage multi-factor authentication from a single point is the biggest benefit to this software. When you have disparate systems, all offering their own implementation of MFA, management becomes an issue. Duo solves that issue.

    Cons

    The administration interface takes a while to get used to. If you stay away from it for a while (when no one has any issues with it) it takes a bit to re-orient yourself.

    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.

    I was solving authentication, I will be investigating switching to another MFA solution as soon as possible.

    Pros

    Our company switched Managed Service Providers, and we used DUO. When we switched over, DUO authentication stopped working. We had multiple users who DUO simply stopped working for. We and our MSP were unable to contact DUO support after multiple hours. I did get through to a person who put the phone down and appeared to be watching a video on YouTube in the background for about 10 minutes and then hung up on me. This had a serious negative impact on our business and I'm surprised that we were unable to get anyone to assist at all with such a business critical feature.

    Cons

    That when support is needed you can spend multiple hours on hold without any assistance. When someone does actually pick up the pick up the phone and place it on their desk and do not actually answer the call.

    Helped us with Cyber Security compliance so we can bring our insurance premium down. A big cost saving!

    Pros

    Easy to deploy to multiple machines manually or at once, the admin portal is easy to follow and allow exceptions. Cost is very down to earth!

    Cons

    Sometimes as an MSP, we've a common Support login account and we want to have multiple members in our team authenticate via MFA using their own devices. The product does not give option to do so via the Duo app, although it is possible to have a security code manually used for MFA (which lets us use the product that way).

    Hassle free two-factor authenticator

    Reviewed on 22/06/2021

    Pros

    Regardless of the technology or platform which are targeting to integrate the multi-factor authentication Duo Security provides the flexibility to integrate with the largely used identity platforms/providers. The use of the app is very easy and convenient with the enablement of biometric authentication. For the authorization process, it takes just one click. The app is that user-friendly. Not like other application available Duo is really easy to use and integrate.

    Cons

    Nothing that I can think of that I like least.
