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.

Multi-factor security has improved device protection but still needs broader application coverage
Fortinet FortiAuthenticator could be improved in its cost structure. Although it is not expensive, other solutions offer more value for less money. Cisco Duo provides better value in this regard and connects to web applications much more easily, scaling effectively in that sense. While I have never used Cisco Duo to secure other devices in IoT environments, I know Cisco Duo is capable of doing so, whereas Fortinet FortiAuthenticator cannot. Additionally, Cisco Duo is also cheaper. These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available. Fortinet FortiAuthenticator was primarily missing the ability to scale to web applications.

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

"I appreciate the secured push feature of Cisco Duo, which requires you to choose a number, because it enhances the security of your users, especially when combined with geolocation for a Verified Push, benefiting my company and our customers by making logins much more secure."
"What I appreciate most about Cisco Duo are the security features it brings to our network environment and machine access."
"The product is reliable and easy to use."
"It's easy to deploy. It's easy to manage. It's easy to integrate with other applications."
"We get fewer threats to remediate due to the two-factor authentication, which does not allow as many threats through."
"Duo features benefit my company by making logins more secure and simpler. Everything is in one box, so we don't have multiple servers trying to do the same thing."
"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."
"We're working remotely. It helps us keep people more safe. Its adoption has been fine. I like the fact that you can bypass it if you need to because there are situations where the internet doesn't work, etc."
"We have a perpetual license for 2FA."
"FortiAuthenticator has made our operations secure."
"In terms of benefits, the tool provides both cost savings and efficiency, but efficiency is more important for our customers."
"The product's initial setup phase was easy. It is also easy to deploy."
"The most valuable aspect of the solution is the security; it's great."
"Once you configure it properly, it runs fine."
"The solution is stable; I installed it two years ago, and we rarely check the internet for changes because it's really stable and we don't have problems."
"The most valuable features are the performance and ease of use."
"The product’s most valuable feature is its ability to assign only one password for the user at a false value."
"Red Hat SSO has a lot of very concise, well laid out documentation, which is available in the free edition as well."
"I like that the solution is open source and you can use a commercial edition of it without any charge."
"Good support for single sign-on protocols."
"It is very easy to scale and use as you want."
"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 integrates well with our other solutions. Using OIDC protocols and ITL integration, employees can authenticate with Red Hat SSO and access our microservices."
 

Cons

"I wouldn't mind seeing some options for remembering a device for a short period of time or a specific login, particularly for administrative engineering staff, as we may be logging in to four or five different services."
"Cisco Duo could be improved by building the agent with the many agents we already use, such as Cisco AMP and Cisco Secure Client, which would simplify our environment by eliminating the need for a third agent for secure applications."
"Cisco Duo could benefit from improvements in certain areas that are important to us."
"Regarding the pricing of Cisco Duo, we are actually leaving because of that. It's something that we are not going to continue with due to the cost."
"We had a lot of trouble configuring the password reset function, and as a result we now have a second channel that bypasses Duo to allow users to reset their password."
"Regarding the pricing, setup costs, and licensing, I find that for some companies using Azure, they question why they should switch when they already have Microsoft Authenticator, which can make it commercially challenging when explaining why they need to transition to Cisco Duo."
"Cisco Duo can be improved, but additional features that should be included in the next release are not my area of responsibility."
"I know that Cisco Duo is pretty expensive; we have affiliates that use the Microsoft product just because Cisco Duo is so expensive, and they don't want to pay for it."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"I have had stability issues with FortiAuthenticator."
"The GUI is not fancy enough and some of the settings are difficult to access."
"The only way the solution could be improved is if it were cheaper."
"For scalability, you need to size FortiAuthenticator properly. It's not 100%, maybe 80% on the scalable side."
"The GUI has some shortcomings and can be made better. The GUI is not great."
"FortiAuthenticator should integrate with other applications."
"There are some protocols, such as SHA and SHA-2, that are not supported."
"The product’s technical support services could be better."
"Red Hat SSO's architecture could be updated."
"Security could be improved."
"I think they could provide additional features in terms of users trying to manipulate the system with regard to security."
"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 publishes much more and communicates its actions and plans. They could provide words, maps, and other resources."
 

Pricing and Cost Advice

"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"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."
"It was very reasonable."
"It's very simple. Its price is fair. We use the hardware tokens as well. You get what you pay for. In terms of licensing, Cisco has very complicated products, but Duo Security was surprisingly easy."
"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."
"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."
"I rate the product pricing a seven out of ten."
"The price seems okay. It's not that expensive compared to other authenticators."
"The customers need to pay for licenses, and some pay on a yearly basis while others pay on a three-yearly or five-yearly basis. Also, it is not an expensive solution."
"The solution is not very expensive."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The product has affordable pricing compared to other vendors."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"I rate its pricing a three to five out of ten."
"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."
