Supports seamless authentication for users across multiple organizations and personal portals
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.

Easy to use, reliable, and offers a straightforward setup
We are customers and end-users. We've dealt with the solution for a long time. We've seen how they developed as a startup, and how they've matured over time. They're actually quite advanced and they are sometimes cutting edge compared to other competitors. I'd recommend the solution. They do things very differently. They're very advanced and they're standards-based. They basically have got a very good vision in terms of how they do strong authentication. Other companies are actually following suit and following what they've done to support standards. They're quite advanced and simple to use, with a good support model. They have the edge compared to other solution providers. In general, I would rate the solution at an eight out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It's a lot easier for our end users to connect to our network. You don't have to type in a code. You get push notifications, that's probably the best thing about it. The fewer clicks they have to do to be online, the better it is. They can easily get into the network and do remote work."
"Cisco Duo seems very scalable; in my experience, I started with a small-medium business, and in my last contracting position, it was a large one for a major worldwide airline that had hundreds of thousands of devices that could use Cisco Duo, and it scaled very well."
"The experience my clients have with Cisco Duo is mainly good, there are sometimes some problems, but not major ones, so it is a solid security product."
"What I most appreciate about Cisco Duo is the ease of use."
"I lead an IT organization that has a significant amount of technical debt, and we're not in a zero-trust architecture yet. I'm pushing in that direction. Duo helps me considerably with my identity in an environment where I don't have zero trust. It's helping me bridge the gap until I can build a zero trust architecture."
"The most valuable feature of Cisco Duo for us is the multi-factor authentication."
"In my opinion, the best features Cisco Duo offers include its 2FA authentication, which is very good, everything is perfect about the features, it is very easy to use, and the integration with other systems is very good."
"It was a simple way of providing two-factor authentication for remote access when we hit the COVID pandemic. It was very easy and quick to get it going."
"The technical support is quite good."
 

Cons

"Cisco Duo's customer support needs improvement."
"We use Yubikey for pushing it to the phones. Yubikeys can get expensive because people tend to lose those for some reason. Fifty dollars a device is pretty high."
"An improvement for Cisco Duo would be a simplification of the licensing model since it's quite complicated to know what's included or not, especially now as it's part of Cisco Secure User Suite, and there are many modifications happening regarding the licensing."
"We have users who move throughout the world, and their levels of connectivity change. It can be a challenge, if someone is in Bahrain, to authenticate via Duo."
"The price of Cisco Duo could be better."
"We first deployed Duo Security for our company with the VPN, and afterward, about a year later, we implemented it for a customer of ours where we offered infrastructure as a service. When I tried to establish a VPN connection through Duo Security, it did not function well on that version, which was the latest one at the time. So, I had to make a copy of the machine and then implement Duo Security with the VPN because it did not function well with the newer version."
"I would appreciate it if Duo Security could improve its integrations with Windows Hello."
"There was an issue related to integration with third parties."
"There's nothing wrong with the solution that we can see. However, maybe they could improve slightly by incorporating decentralized identity blockchain models into their solution."
 

Pricing and Cost Advice

"It was very reasonable."
"With regard to pricing, for a small business buying a one off, it's pretty expensive. If it's an enterprise that has thousands of employees, however, it's really nothing to protect your data because if your network goes down or it's breached, you're losing millions of dollars every minute. When it comes to a large enterprise, it's priced where it should be because you're talking business to business. You're not talking business to consumer."
"You pay per user when using this solution and the pricing is fair."
"I haven't seen it in a while, but it's at par with everything else licensing-wise."
"It has a fair pricing model. I know they have different tiers, but it would be nice to have different types of licenses for certain groups of users in our organization. That way, we wouldn't have to lump everybody into one group. That would be also one complaint."
"Their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. There are no additional costs to the standard licensing costs."
"Price-wise, the solution has been very, very reasonable...Licensing is the last thing I think about Duo Security because it's so easy, and I had no problems with it."
"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."
