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
It is a very compete and solid solution Once it is in place, and you have configured the different settings and policies it is consistent and works well. It does take some time to work the kinks out. We had a Cisco support provider assist us while we stepped through the process of getting it set up.
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.
Documentation is oftentimes missing key information for proper implementation. This is circumvented by reading third-party guides or contacting support for additional details.
They do not push Fail-Closed as much as I think they should. Fail-Open is fairly trivial to bypass and it should be made known to the customer during setup how much this will affect overall security.
More vendor integration is something that is always craved by administrators. There are so many third-parties to integrate with.
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.
Implementation was straight forward and you can isolate different scenarios in order to test new application setup or add to an existing setup. Gui interface is pretty easy to understand and follow. I had no experience with Duo and still manage to easily set up new policies and rules.
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
I would fully expect a competitor like Okta or any other multifactor mechanic to function pretty similarly, and I hesitate to say duos the best. I think the idea is that it's a simple concept, but it does it well. So I haven't evaluated any myself outside of duo, but I'm also not in the market and I don't feel like we need to go shopping for something else.
