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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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

I have used Duo Security since the university I work at implemented it a few years ago for our duo login. It has been easy to use and I have enjoyed it since they implemented it. I have used the app for the quick login and it has been great!
Pros
This software is easy to use. Once my work shifted to this, I was able to easily understand and pick it up. Having the app on my phone also makes the duo authentication very quick or sometimes I will also have the system call me! Either way, it is great.
Cons
There are no cons about the software. I think it is a really great option for a duo authentication and I have nothing negative to say about it.

Overall Duo has helped us improving device security and we were able to integrate with our Palo Alto Firewall devices and had pretty smooth experience.
Pros
This worked pretty smoothly, when logging in the security devices such as firewalls, with duo we made sure no unauthorized users is logging into the devices with Multi Factor Authentication mechanism. With duo we simply were able to compliance with Zero Trust Model, no unauthorized users can make the changes on the system.
Cons
They can work on their mobile application and make sure to improve the user experience, I feel bit delay while receiving the authentication request. Also on mobile app they can make it like only one finger touch is enough to authenticate the user. So less clicks can make the experience way better.

Overall, because of these two experiences. I am genuinely going to look into an alternative option and preferably leave Duo as a personal preference. I love how secure it is but it's not okay to have a safety exit that doesn't work - like come on?
Pros
No one will ever get in to your apps or info
Cons
If you need to get in, you won't be able to. I had a phone stolen, and then unfortunately lost not long after I got a new phone. I had my back up codes saved when when the first one was stolen - did not let me into any of my apps and the worst part is - they give you 8-10 codes to use for a 'back up'. When the first one was stolen, I was extra safe and careful and then I sadly lost that one and I could, once again, not get into a single app using my back up codes.

Hassle free two-factor authenticator
Reviewed on 22/6/2021
Pros
Regardless of the technology or platform which are targeting to integrate the multi-factor authentication Duo Security provides the flexibility to integrate with the largely used identity platforms/providers. The use of the app is very easy and convenient with the enablement of biometric authentication. For the authorization process, it takes just one click. The app is that user-friendly. Not like other application available Duo is really easy to use and integrate.
Cons
Nothing that I can think of that I like least.
