Featured Reviews

Charles Slaustas - PeerSpot reviewer
Information Technology Contractor at Insight global
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.
Giovanni Baruzzi - PeerSpot reviewer
Owner at Syntlogo GmbH
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 anti-phishing feature is the most valuable."
"Examples of how these features have benefited my organization include that end users are happy and I am happy because I do not have to constantly monitor it every single day."
"My advice for other companies that are considering getting Cisco Duo is to try it, and you will be amazed at how easy and how productive this tool is."
"Overall, it meets all my needs, including price point, and I've been very happy with it."
"The technical support is of a very high level, and if you have a problem they will be able to support you, logging in remotely as an engineer to give assistance, and with the upgraded license the support is even better and they will do everything for you if you have a problem, so the support is extremely good."
"Cisco Duo has strengthened the ability to defend against both phishing and identity-based attacks."
"The biggest overall impact of Cisco Duo on our company has been the peace of mind it provides, helping us sleep a little more soundly at night knowing that we have that layer there, and operationally, it has fostered more trust when it comes to logging into systems."
"I love Duo Security's push notifications. It's simple, fast, and secure. From the user's perspective, the solution is seamless. The security aspect is great."
"Good support for single sign-on protocols."
"I like that the solution is open source and you can use a commercial edition of it without any charge."
"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."
"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."
"The product’s most valuable feature is its ability to assign only one password for the user at a false value."
"It is very easy to scale and use as you want."
 

Cons

"The only issue is the price is too high when compared to other products; Cisco Duo's pricing is high."
"However, I know that sometimes integrating it with the Linux environment is a bit of a pain."
"My experience with Cisco Duo's strong security authentication system is that sometimes there are difficulties, and sometimes users just won't be able to log in. We have to reset their password so they can use Duo."
"If I could improve Cisco Duo, I would suggest providing some notification back that the Cisco Duo system was not able to reach the remote device, because I was left in a situation where I did not know if it was actually my cell phone or something was wrong with Cisco Duo."
"We had some trouble with the password reset function."
"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."
"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."
"While two-factor authentication with mobile devices provides a high level of security, it's still not foolproof, as someone could potentially steal your phone. It would be beneficial to have information about the authentication location."
"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."
"Red Hat SSO's architecture could be updated."
"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."
"I think they could provide additional features in terms of users trying to manipulate the system with regard to security."
"Security could be improved."
 

Pricing and Cost Advice

"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."
"The licensing is very good because it does not cost a lot of money. It's affordable for all-sized customers, including enterprises. There is an additional cost for premium support."
"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 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."
"I am not aware of the pricing. There are two departments, and I don't have any information about them."
"I rate the product pricing a seven out of ten."
"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."
"The license is around $8000 USD."
"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."
"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."
