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.

Quotes from Members

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

Pros

"It is a good solution for hybrid environments and VPN."

"The solution is pretty secure."

"All features of the solution are effective, particularly those involved in identifying vulnerabilities and updates."

"My overall rating for the solution is ten out of ten."

"The most appealing feature of Cisco Duo is the phone notification system that simply pops up on your phone."

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

"The deployment and installation process for Cisco Duo is quite straightforward, which is an advantage."

"The authentication process is very smooth and secure."

More Cisco Duo pros

"We find that the product scales very well."

"One Identity Defender has good network protection."

"It's very fast, and it's easy to use because it's integrated with Active Directory."

Cons

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

"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."

"For upgrades, there should be a better notification of when they're coming out. We always have a testing phase, so we need to be ahead of it. It takes us longer before we can upgrade to the newest version."

"I would like to see Duo Security increase the time that the users have to log into the devices. The maximum time interval is 50 minutes at the moment, and I would like it to be 60 minutes. When you try to log into a device and have to authenticate yourself, sometimes it's not very pleasant. It's not the best thing particularly if you have to do this every 50 minutes, which is the maximum time that Duo gives. This makes it difficult to use and does not save time."

"General announcements when new features come out with Cisco Duo should be broadcasted to customers who are using it, which might bring more accessibility to their documents so users can be more in tune with updates."

"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."

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

"Cisco Duo is stable, but occasionally there are emails about incidents that affect some services temporarily."

More Cisco Duo cons

"We have some clients that are wanting to protect their Apache web servers with One Identity Defender but all the research I have done says cannot be done. It can only be oriented to an IIS server. One Identity Defender should have more integration with more types of web servers."

"The login capabilities could be better."

"Maybe it could provide support for more web applications. It seems more focused on IIS web applications."

Pricing and Cost Advice

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

"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 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."

"I am not aware of the pricing. There are two departments, and I don't have any information about them."

"I haven't seen any information on the pricing in four years, so I can't comment on that."

"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."

"Duo Security is free."

"The cost was reasonable. Licensing was pretty straightforward for a change."
