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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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

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.

Our users and administrators have both given positive feedback with using Duo. I would recommend to organizations looking to have reliable and secure logins.
Pros
Multifactor authentication has been effective at making users have to sign in securely to our networks. Duo admin console is easy for our techs to learn and user setup takes a few minutes to complete. The device and user management for sign-ins allows us to manage the authentication more effectively.
Cons
We have experienced the admin console inaccessible at times when there have been updates or outages. The timer for accepting pushes doesn't always sync up correctly.

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.

Best For MFA
Reviewed on 17/08/2023
Duo was an easy transition into the MFA world for external access to our internal systems.
Duo was an easy transition into the MFA world for external access to our internal systems.
Pros
It can integrate seamlessly with all platforms and apps of our organization. Easy to install, use, track, and recover from lost or damaged phones. It has push notifications and also alternate access via text or call.
Cons
Sometimes it takes a couple of times to sign in to a network.Sometimes due to poor data access on the end user part, a push notification doesn't come up although data is available, Which leads to a timeout. A little bit difficult in the initial configuration.
