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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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

    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.

    Duo security works perfectly to add additional security to our login process.

    Pros

    I like the simplicity of the multifactor authentication process. It was easy to deploy on our phones and works perfectly each day.

    Cons

    I do not have any cons to list. This product functions as it should and does the job. Compared to the product that we switched from though, I do feel that DUO provides less security.

    Duo makes your information safer, and it does help make you feel more comfortable with the information you have online, but it does have flaws and takes time to fully complete the authentication process that is not there otherwise.

    Pros

    Duo security is an app on your phone and a computer program, so it is versatile and helpful in protecting your passwords and various accounts. In school, it is a great way to protect tuition information, grades, and various other lovely stuff we do not want people to know.

    Cons

    The app can sometimes lose connection with the cloud, so an authentication won't go through, or there can be issues where the app does not receive a push or a request. This can be difficult as there is no direct way to troubleshoot, you just have to restart the process.

    Beware! Customer service has been non-existent following Cisco acquisition

    Reviewed on 10/03/2020

    Pros

    We have used Duo for many years. It was easy to implement and has always worked well.

    Cons

    Last year we negotiated bulk pricing and paid in advance for a 14-month term. Later we discovered that they had never provisioned our licenses and were still billing our credit card. Now, four months later, after numerous phone calls and more than a dozen emails, they have still not provisioned the licenses we paid for. They have acknowledged that this is their mistake and they need to fix it, but they seem incapable of doing so.

    I get the sense that their organization is completely dysfunctional following the Cisco acquisition. Given that they cannot solve the challenge of "how does a customer purchase your software?", I am worried what might happen if you came to them with anything more difficult.

    Good experience overall, and it is not a hassle to use Duo. I have heard very few complaints from other students and colleagues at my university.

    Pros

    Duo makes it very easy for me to log-on to my student account at my university. I like how it is intuitive to use on iPhone especially, and it gives me the option to call or text my phone. I rarely use the "call" feature, however, because I am always using wifi. The Duo Security app pops up immediately, and I am able to approve the request quickly from my phone. I feel very secure with this software, especially since the pin changes every few seconds.

    Cons

    I don't always have my phone with me, which makes it impossible to log in. I wish there was a feature where I could receive an email instead of a call or a text on Duo. I have not seen this feature at all, but it would make my life easier.
