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.

A stable and flexible solution with some basic capabilities

I set up Red Hat Single Sign-On in half an hour. I had to install a single sign-on solution for a customer. I reviewed a list of all available products, which were no more than fifty, and analyzed them. I chose it because it was convincing, modern, and based on technology from 2015. I put my trust in this product, and after nine years, I feel confident in my decision. Deploying this solution usually takes half an hour. You need an operating system running, then deploy the packages and prepare the interfaces. I rate the initial setup a ten out of ten, where one is difficult and ten is easy.

Quotes from Members

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

Pros

"The two-factor authentication is valuable because that is the use case for which we are using it."

"The most valuable aspect is the authentication and the SSO."

"Cisco Duo has benefited our company overall by giving us the ability to have multi-factor authentication."

"The ability for users to authenticate via phone, from any random phone number, has been very helpful for managing a distributed workforce. Using it across a distributed network for securing access to our applications is big for us."

"Documentation is the most valuable feature, and if you ever have to reach out to them with a question, their support is also fantastic."

"The single pane of glass management works very well. That feature is very important because we have a lot of admins who have to manage Duo, and it's much easier when it's a single pane of glass. That single pane is also great because it's easy to enroll new devices."

"For me and my customers, the best feature is that it's very easy to integrate with the existing infrastructure. It takes a few minutes to configure it."

"The most valuable features of Duo Security are visibility and OTP authentication. The OTP is very important because it is a self-enrollment feature, you are able to enroll users very quickly with a shorter time period."

More Cisco Duo pros

"The solution is flexible and has the same basic capabilities right out of the box. The most important feature of this product is that it is a Red double-sided product. One side is a well-known open-source project; the other is a Red Hat commercial product. The commercial product benefits from all the experience and contributions of the community, making it a very well-developed product."

"It is very easy to scale and use as you want."

"Good support for single sign-on protocols."

"The product’s most valuable feature is its ability to assign only one password for the user at a false value."

"Red Hat SSO integrates well with our other solutions. Using OIDC protocols and ITL integration, employees can authenticate with Red Hat SSO and access our microservices."

"Red Hat SSO has a lot of very concise, well laid out documentation, which is available in the free edition as well."

Cons

"The only time I really had some negative feedback for them was about the UI of their mobile app, but they improved it in the last version. It is good on the functionality side, but their pricing model is a little bit weird. Currently, there is no price advantage in signing up for yearly contracts. If you are on a monthly term or a yearly contract, you basically pay the same price, and that is very unusual. Normally, there is a discount when someone signs up for the 12-month system."

"The pain point for us at one point was the Duo Authentication Proxy since we're on-premises and not in the cloud. We had to have a proxy machine that's in our DMZ to talk to Duo for us. The configuration of that was a little complicated."

"When you come to the push in Duo Security, there are some integrations where you have to use the code instead of the push functionality."

"We found it difficult to integrate it into our broader product family of Microsoft tools and other applications used across our organization."

"Certain customers can not use this product because it is cloud-based."

"Smart Licensing needs improvement. It's terrible. We have problems with it every year and we need to involve support to fix it."

"There is always room for improvement."

"From an administrative standpoint, I'd love to see it be a little better at remembering a device and location so that I don't have to continually authenticate. That's pretty much it."

More Cisco Duo cons

"Security could be improved."

"Red Hat publishes much more and communicates its actions and plans. They could provide words, maps, and other resources."

"The product’s technical support services could be better."

"They could provide more checks and balances to find out if there have been any security lapses, e.g., if somebody is trying to break into the system. Some other products have these detection mechanisms in case someone is trying to hack into the system or find out a user's passwords."

"Red Hat SSO's architecture could be updated."

Pricing and Cost Advice

"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."

"I haven't seen it in a while, but it's at par with everything else licensing-wise."

"Cisco's licensing is always a bit complicated to understand, but the price is fair. It could be more expensive than others, but the way they integrate everything, it has a fair price."

"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."

"Price wise, it's not cheap, but it's not expensive at all either. It's in the middle."

"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."

"Duo Security is free."

"Its price is reasonable. It is not highly expensive."

More Cisco Duo pricing and cost advice

"It is a low cost product. This product can be used by non-profit organizations or universities, when they don't want to invest a lot of money."

"If you want support, that is when you use the paid version. There are different support categories that you can pay for, which provide different support levels. E.g., there is a quick response if you pay a higher amount, where the response time is within a few hours."

"The license is around $8000 USD."

"Red Hat Single Sign On is expensive."
