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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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

    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.

    It's been fantastic when it works, which is 99% of the time, but man, that 1% is not super fun, but all programs have problems, I'd say this is most likely still one of the best choices.

    Pros

    What I most like about duo security (considering it's application that basically has one purpose with a few different avenues of getting there) is the simplicity. It also is a bit more modern feeling than your email and text authenticators, which is nice. I'd say that this program, if you're looking into authenticating software's, is most likely one of the best choices, next to microsoft's.

    Cons

    I've randomly (very rarely) had my duo logins just removed from the app, and it is a HASSLE to get everything back ESPECIALLY if you are incorporating this into a business. You're basically having to prove duo screwed up to try to get your authenticating account back onto the program, without having it on the program, it's not super fun, but at least it doesn't happen very often, other than that, great program.

    Duo Security is necessary and useful when trying to protect your secure access to portals and data online. However, this company hasn't quite worked out the delays and programming bugs that still come with the app.

    Pros

    Duo Security does resolve many issues with sensitive information and secure access, as the approved user is given sole access by having this app on the user's phone.

    Cons

    There are numerous delays in alerts and sometimes it appears that programming bugs cause the app to malfunction, even when using the latest version of the app.

    Never had any problems with Duo. I broke my phone once and couldn't authenticate myself to get into any important accounts since it was all tied to my phone only. Duo allowed me to get into my accounts that day fairly easily by giving me temporary backup codes until my phone was fixed.

    Pros

    Duo is simple to use, user friendly, and does all that is needed for authentication. I work with multiple large organizations that have chosen to use it for their employees. It is easy to pair duo with new organizations as well.

    Cons

    So many authentication apps exist, that it is hard to distinguish between them. Duo works great, but so does basically every other authentication method in the app store.
