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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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

    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.

    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.

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

    Reviewed on 10/3/2020

    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.

    Duo is a product that gives me peace of mind, I am sure because I know that I am the only one who can access my personal data through login or websites.

    Pros

    In fact, Duo Security, give me a lot of security to work the only one who can access my base without restrictions and without any kind of problems, and a wonderful product, I like using it more, very good to know that I can count on you this software for any type of safe and effective work.

    Cons

    It could be more practical, I didn't need to confirm every time you enter a Sait, so it gets a little tiring and a little difficult for those who are beginners. The Duo could improve in the following way, not asking for a reminder every time you log in to your device. "Remember" a device, so that personal work is not so exhausting
