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

"Cisco Duo helps minimize the risk of attack vectors and prevents unauthorized access to our data since it's tied with multi-factor authentication, which helps block threats."

"It has continuously evolved by introducing new solutions and products to address emerging security threats in our industry, demonstrating its commitment to staying ahead of evolving security challenges."

"It's simple. It's reliable. I haven't had any issues with it."

"If you have to log in to something, you must go to Duo Security to confirm that you're who you are on your phone."

"The ease of deploying Cisco Duo Security and onboarding has greatly benefited our customers."

"Cisco Duo is quick to deploy and easy to start."

"We were considering purchasing other products, like AMP for Endpoints, and it was not properly integrated with the firewall function. It might be better now with SecureX."

"Clients I implemented Cisco Duo at immediately feel more confident in their security environment, and we can see a lot of illegal attempts to get in, giving me faith in the product."

More Cisco Duo pros

"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."

"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."

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

"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."

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

Cons

"Technical support could be improved. I don't think all support should have to go through an agreement."

"More automation and device insights would be helpful in achieving a seamless single pane of glass. Having the additional capability to streamline processes would also make things better."

"For the back-end, there could be a few more security features applied."

"There was an issue related to integration with third parties."

"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."

"It already integrates with lots of products, but it can integrate with more products. There should be easy integration with Cisco products because sometimes, it can be quite complicated."

"Duo Security could be improved with the addition of more applications."

"I have not seen ROI with Cisco Duo; probably the opposite, because it impedes productivity time to be able to get into the system. You have to authenticate and do your regular login and your Active Directory logins."

More Cisco Duo cons

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

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

"Security could be improved."

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

"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."

Pricing and Cost Advice

"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."

"From a reseller perspective, it's still challenging to explain the whole license strategy to a client, so we really have to be ahead of that for all the true forward conversations."

"I believe the licensing model is excellent as it offers flexibility to our customers, allowing them to adopt a crawl, walk, or run approach."

"Duo Security is free."

"I only need the solution for IT staff, which makes it relatively cheap. If I deployed it for the whole company, it would be costly, so it depends on the number of users. Duo Security is affordable compared to other products in the segment."

"My experience with pricing, setup costs, and licensing has been good, with no issues. I am pleased that the prices remained stable after Cisco acquired the solution."

"Our licensing fee is currently on an annual basis."

"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."

"Red Hat Single Sign On is expensive."

"The license is around $8000 USD."
