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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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

    It's all about security

    Overall, Duo gives me peace of mind knowing that I am the only one that can access my personal data base from log ins and websites. I like knowing that I can approve or reject any log ins from the commodity of my phone.

    Pros

    Duo is a great option to keep your personal information secured. I like that it requests security validation before logging into websites, and that you have the option to use the app to sign in to any device with a few taps. It is easy to use once everything has been set up correctly.

    Cons

    It can be hard to understand at first, and it might seem a little annoying to have to confirm you are the one logging into your websites every time, but it gets easier if you have the app. Another thing Duo could improve on is the fact that it only lets you "remember" one device at a time. Sometimes I need to log in from my work laptop or my personal laptop and it becomes tedious to remember which device I have registered.

    Duo Security is a strong SaaS product to fill the very specific infrastructure gap of 2-factor authentication for infrastructure.

    Pros

    Duo Security is a great product to fill a very specific gap in infrastructure security, specifically for SSH management. For requirements for 2-factor authentication for SSH, Duo is quick to implement

    Cons

    Duo is difficult to enroll users with, which creates a significantly higher administrative overhead than other options. There are also significantly more delays in the Duo pushed-based notification systems (depending on the user and their network, etc.), which can cause issues for users authenticating.

    Reasons for Switching to Duo Security

    G Suite SAML login was more difficult to implement in very specific situations than simply purchasing Duo. In the future, the goal is to move to a more BeyondCorp style model where each specific application can use SAML and not rely on Duo

    Security at your fingertips... Literally!

    Duo has helped me meet my university single sign on security requirement for access to my account. I especially appreciate that I can use Duo with multiple accounts at once. That feature has been the best because I didn't actually have to set up anything new.

    Pros

    This product keeps your accounts safe and secure. With increasing use of single sign on for workplace accounts, Duo has been useful in providing the multifactor authentication my university requires in order to access my account. One benefit has been the ability to use Duo for security authentication with two additional accounts. Having one program to help manage access has been critical. It's easy to use, once you have made the initial installation, and provides secure authentication with the simple selection of "approve" or "deny" from the notification message itself.

    Cons

    The initial integration was a bit counterintuitive. Maybe it was that I was new, but once I got over that initial hurdle, it was great.

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

    Reviewed on 2020/03/10

    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.

    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.
