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 Users can be automatically notified of outdated devices, with direct links to update to the latest software version, provided a set number of login attempts before application access is blocked, or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

An Extra Layer of Security

Overall, it's been a great experience. We implemented it so that we could have unified MFA over multiple platforms--VMware and M365, for example. It also gives users who don't want to use an app on their phone the option of using a hardware key. Setup and integration isn't too rough and the support is excellent.
Pros
Being able to manage multi-factor authentication from a single point is the biggest benefit to this software. When you have disparate systems, all offering their own implementation of MFA, management becomes an issue. Duo solves that issue.
Cons
The administration interface takes a while to get used to. If you stay away from it for a while (when no one has any issues with it) it takes a bit to re-orient yourself.

I am satisfied with this software because it does what it says it will do. Provide that extra security to your login.
Pros
That it helped keep my login secure, it is no longer just a password that is needed but you also need to be able to authenticate who is trying to login to your account and I think this software is the way to go.
Cons
That it is a little annoying to setup in the beginning but after that it is easy.

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.

Duo is great for PCI compliant companies
Reviewed on 13/12/2022
Pros
Duo is great for PCI compliant companies wanting to have their employees working from home
Cons
Sometimes you will have to go back on and re-authenticate, which may also be considered a plus for extra security.
