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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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

    I enjoy the endpoint security perspective of the application coupled with the simplistic user interface - this is very good for non-tech users working remotely.

    Pros

    I like that Duo let's you know what might compromise your experience on a platform. It tells you to upgrade your android/iOS handset and gives a severity level. This is great from an endpoint security perspective.

    Cons

    At times - the app takes a little time to prompt the user that an attempt is being made. This may be a function of slow infrastructure, but it is hard to assess.

    Nice Little Authenticator App

    Reviewed on 5/5/2022

    Pros

    It's quite simple and easy to incorporate into simple software/systems that require multiple user access. Easy to add systems and accounts to its setup and easy to navigate.

    Cons

    It doesn't allow for automatic pushes to be sent once you are trying to log into a software or system. So you have to click to send the push every time and with the experience of other authenticator apps, you might end up forgetting you have to manually pushing it.

    If DUO doesn't work, expect your company to be shut down for an unknown amount of time

    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.

    The software was literally installed in less than 5 minutes with the help of our IT departments. Multiple questions along with your personal log in allows this to serve as a protection not only for the clients we serve but for me as well should anyone ever attempt to access using my identity.

    Pros

    This process is ABSOLUTELY a must have in todays cyber world. Using a dual authentication system to access your internet services was easy to set up and even easier to install and use. Any work environment where sensitive or personal data, demographics, or financial information should all be required to provide their employees with this type of DUO security. It is installed easily with the use of your IT department and changes, revisions, updates are also handled by them as well. It truly is a better way to make sure we are doing all we can to keep our internet and services safe.

    Cons

    Honestly I had no issue with the install or the software.

    DRL's Duo Review

    Reviewed on 15/6/2022

    Pros

    Very simple multifactor authentication process which was easy to deploy on all employee phones and seems to work without any hiccups.

    Cons

    Quite frankly, it can get really irritating and overwhelming to have to go through this song and dance every time you want to log into a network server. In a multi-tier/multi-server environment, you need to have a lot of patience for this because it can get very tedious.
