Microsoft's Azure Multi-Factor Authentication was an MFA solution acquired with PhoneFactor in 2012. From 2018 it is no longer available as a standalone product. This functionality is now provided by Microsoft Entra ID.

Cisco Duo is a two-factor authentication system (2FA), acquired by Cisco in October 2018. It provides single sign-on (SSO) and endpoint visibility, as well as access controls and policy controlled adaptive authentication.
As a former user of PhoneFactor the predecessor to Azure, I found Duo to be simple to Install, Configure, Manage and use. Duo also offers flexibility for users that are not part of a companies BYOD program. PhoneFactor required more administrative support than does Duo.
Duo is the easiest one to use and definitely has the fastest turn around for sending you a code. I really enjoy using Duo and would recommend that anyone use this for their MFA.
As we were on Cisco VConnect mobility client, we felt the ROI of using a Cisco auth client would be much better even though when we took this decision, remote working wasn't in vogue. That's the main business reason for going with Duo / Cisco Secure Access, by Duo--a …
If your solution falls within their standard use case or you have Office 365 - then it makes total sense. If you need a lot of customization or have a really specific business process that causes you to deviate from the standard flow it usually makes more sense to create a custom solution
For secure access to apps and business data, I recommend Cisco Duo. It offers SSO, MFA, and Passwordless access, ensuring teams can securely access business data. It is easy to customize and comes with top-tier security features. It protects business data, apps, and users.
We use Cisco Duo with different type of device and application, but we never face any difficulties to integrate Cisco Duo with any of them.
We integrated Cisco Duo with some of our active directory and some of the OS are quite old but Cisco Duo works totally fine with them.
The end user application is very easy to use. We never had any complain from non tech team members of having trouble of using Cisco Duo.
There are several authentication methods available rather than passcode. I personally like the push notification which is always on time and quite fast.
Should have device to device connection ability whereas internet is not met.
Changes of device can be sorted and easily made using a second email address or any other identification method.
Troubleshooting should be easy to sort out. One time, a Duo admin deleted the authentication group, and some employees were not getting push notifications. It was very hard to find out the cause. Duo should have some troubleshooting finder.
Sometimes push notifications are delayed, and the code does not work. At that time, we need to enroll the device again. Not sure why it happens. Duo should give reasons for the error.
There are a lot of competing solutions on the market; however, Duo "just works", and there is little to no learning curve for the new members to be acclimated to it. As long as that continues I see it as the preferred option moving forward
La interfaz es intuitiva y fácil de navegar, lo que permite a los usuarios administrar sus dispositivos y acceder a las políticas sin problemas. La integración con las aplicaciones SSO y SaaS facilita aún más el proceso de acceso, mejorando la experiencia del usuario.
In the last 5+ years we've been using Duo, there may have been 1 outage that impacted us. We do receive periodic notifications of issues but, for the most part, they impact carriers or functionality that we either don't use, or do not care about.
I have not needed direct support for Cisco Secure Access by Duo as I have not had a problem with it, but I have full confidence that the support is outstanding. It is now a core component of the corporate technology stack - a problem would mean a serious degradation in the ability of the company to function.
Documentation could have been better. I had to piece together different KB/admin guides to make certain things work and I also had to use third-party guides to get bits of information that were missing from Cisco Duo documentation. Support was also engaged multiple times to figure out an issue and after some back and forth it was usually determined that the information I needed was hidden somewhere else and had no direct correlation with the document that was linked from the platform.
Honestly, they are very similar as is much of their offerings. It really comes down to which ecosystem are you already invested in? It doesn't make a lot of sense to try and interop with every cloud vendor - pick one and use them. While there used to be substantial differences in the cloud platforms, they are at basic parity now
Ultimately we ended up going with Cisco Duo because we are a Cisco shop. All of our networking infrastructure, our phones, our wireless environment is Cisco based. It made logical sense to stay with a product that we already have a line of support with. With a smaller support / tech group we depend on outside Cisco support. That support is already here for us, so we stayed with a Cisco product.
Cisco Duo has saved us from automated attacks on VPN. We had an instance is 2024 where our VPN was being brute force attacked, and we had several users' weak passwords compromised; however the VPN security groups, and the MFA kept the attacks from gaining access. We've since replaced our firewall with capabilities for limitations on country access for VPN, and beefed up our password complexity settings,
