"Effortless MFA Rollout with Smooth Self-Enrolment"
4.5/5
What do you like best about Cisco Duo?

The roll-out was the easiest part. We had MFA enrolled across the org without a drawn-out project, and the self-enrolment flow meant there was very little hand-holding needed. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

There were only a few issues. The main one was that the login flow required one additional setup step. As a result, there’s an adjustment period for users who haven’t used MFA before, but that feels more like the nature of the product than a flaw. Review collected by and hosted on G2.com.

"Reliable, Easy-to-Use MFA—But Occasional Hangs and Authentication Failures"
3/5
What do you like best about Cisco Duo?

Cisco Duo's phishing safe MFA is reliable tool which gives IT team peace of mind and it is easy to use. It's GUI is simple and easy to use which makes it a great tool. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

It hangs sometimes, and authentication fails, which is a big letdown. The notifications are also a major letdown and really need a lot of improvement. The cost could have been better as well. Review collected by and hosted on G2.com.

"Easy, Secure Duo Authentication That Just Easy to use and gives you a little extra peace of mind"
4.5/5
What do you like best about Cisco Duo?

Honestly, Duo is just easy. I get the notification, approve it on my phone, and I’m in. It adds that extra layer of security without making logging in feel like a whole process. Once it’s set up, you really don’t have to think much about it. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

It can get a little annoying when you have to authenticate more than once, and switching phones or setting up a new device can take a few extra steps. Nothing major, just one of those little things. Review collected by and hosted on G2.com.

"Cumbersome Setup and Learning Curve, Despite Strong Security"
2.5/5
What do you like best about Cisco Duo?

It's very secure and I feel safe that my accounts are getting logged in without my consent. I know there are a lot of features that can be interesting across different job roles. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

It can be a bit cumbersome and there is a learning curve. I have gotten used to it, but setting it up was a little difficult in the beginning but it is easy to use now. Review collected by and hosted on G2.com.

"Convenient Mobile and Watch Duo Approvals with Handy Notifications"
4/5
What do you like best about Cisco Duo?

I like that it is an app so I can utilize it on my phone. I also get the notifications to approve or deny duo from my watch if my phone is not near by. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

I don't like the time limit. Some times I may get interrupted and not finish my approval before it times out. I wish the time out was longer than what it currently is. Review collected by and hosted on G2.com.

"Clean, Simple, and Rock-Solid VPN Authentication with Duo"
4.5/5
What do you like best about Cisco Duo?

I have been using Duo since way before Cisco purchased the company. It was always easy to work with and easy to setup. The User interface is clean and simple, and it works extremely well. At my former company Duo was a requirement for vpn authentication. Before that we used RSA tokes, and DUO was a lifesaver after that experience. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

The only think i don't like is that when I stopped using it in 2023, there was no offline option, and from what I understand that is still the case. Everything else was flawless in my opinion. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

Since the buyout with Cisco the product development seems to have stopped, while the support and documentation are great I'm not sure about the software development Review collected by and hosted on G2.com.

"Rapid User Responses and Flexible Notification Options"
5/5
What do you like best about Cisco Duo?

The software's responses to the requests from users is quite rapid. End users have options to choose whether to receive notifications via text, or via the DUO Mobile app, etc. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

After setting up new users, their configurations will remain active only for a certain length of time. This can sometimes be an issue, since we set up new users some time before their actual start date. Review collected by and hosted on G2.com.
