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.

Single sign-on saves time by seamlessly managing passwords and improving workflow efficiency
What I appreciate best about Imprivata OneSign are the single sign-on and the Confirm ID features. The single sign-on works seamlessly for all the nurses or the end users out there. You just have to log in to the application once and the single sign-on clicks in and works for everyone. Users don't have to manually remember all their passwords. Imprivata OneSign helps by remembering and storing all passwords. The integration capabilities of Imprivata OneSign offer many possibilities, and there are numerous upgrades Imprivata has been implementing. At this point, they are growing rapidly. There are new tools coming out for reporting and generating real-time analysis. Imprivata E-PAM is a new feature that I've been reading about in articles, which is going to help administrator people and enterprise administrator personnel to view real-time records and views for all end customers. Reporting and looking at logs for the users will be seamlessly efficient. I use the reporting tools available in Imprivata OneSign. The admin console itself has a reporting feature, which gives us a list of pre-built templates of reports where you can see how many users have been added, the user policy, the users who have last logged in in specific amounts of days, and the reporting for the EPCS users. There are numerous reporting options available which help with troubleshooting issues. I have seen many benefits from using Imprivata OneSign. It saves substantial time for nurses. As a nurse or doctor, you don't have to spend time remembering passwords or signing into computers. You just need to grab the nearest machine and tap in. You can use the machine anytime if you want. It saves time when dealing with patients. For doctors who might not be tech-savvy, Imprivata OneSign helps them sign in seamlessly.

Quotes from Members

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

Pros

"I believe Cisco Duo is worth the investment, offering a good return on investment, as it is expensive but works very well without any downtime or high maintenance, and the support is also good."
"From an administrative point of view, I find Cisco Duo user-friendly because the console is very easy to use, and when it comes to the Cisco Duo agent installations, the documents are pretty clear."
"Cisco Duo is an excellent solution to protect our network."
"It has definitely reduced embedding. We found a lot of problems with attackers being able to compromise accounts. Now, when they try to access accounts, they are not able to do so because there is an added layer of protection. Once we know that a username and password are compromised, we just reset the password to protect the company."
"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."
"Cisco Duo is very easy to deploy and the documentation is very thorough, which makes deployment straightforward."
"The features of Cisco Duo have benefited my organization because it's secure, provides a way of accessing the workspace, and it's easy to operate from mobile."
"For me, the biggest return on investment when using Cisco Duo is my time."
"The logs have great detail that make it easier to evaluate and control the security environment."
"The biggest advantages of Fortinet FortiAuthenticator are that it's easy to deploy, easy to manage, and the GUI is a very strong interface."
"It made things much easier for dealing with users BYOD for our secured wireless networks."
"This is a scalable product."
"It integrates very tightly with the rest of the Fortinet ecosystem."
"The product is good, cost-effective, and functionally efficient."
"FortiAuthenticator is a very good solution. It is all jury-based. FortiAuthenticator is very easy for anyone to understand how it works and be able to take action."
"Fortinet FortiAuthenticator is an easy-to-use solution."
"Imprivata OneSign helps customers minimize their work in remembering passwords and enhances their security."
"I have seen many benefits from using Imprivata OneSign. It saves substantial time for nurses."
"Imprivata supports single sign-on, providing a service that allows users to sign in to whatever application they are using, and the deployment is very quick and not difficult to deploy."
"It has benefited my organization in the way that it makes it more secure by making it harder to hack."
 

Cons

"Cisco Duo can be improved by integration into Security Cloud Control, which would be a significant advantage."
"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 could benefit from improvements in certain areas that are important to us."
"Duo has some issues that we're trying to work through. For example, if I install it on a WordPress site and another admin needs to log in, they can't because Duo hasn't been set up for them. It doesn't appear that I can add permissions on a user-by-user basis. It's not obvious."
"I think improving the user interface would be beneficial."
"There are limitations because Cisco Duo does not support Hotmail accounts, which many people use to log in to their systems."
"Cisco Duo is doing exactly what we need it to do, so I cannot really give a suggestion for areas that could be improved since we do not use everything that it currently offers."
"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."
"I think FortiAuthenticator is more expensive than other products like Cisco Duo."
"The integration with third-party tools must be better."
"The product must provide full support for third-party FIDO security keys."
"I don't have any issues with this solution, but it may need a better, more user-friendly interface or better design of the platform."
"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"I have had stability issues with FortiAuthenticator."
"The technical support team is bad."
"The area for improvement in Fortinet FortiAuthenticator is its price."
"Imprivata OneSign should have a landing page because most customers prefer this feature, which is currently a strong point for competitors."
"They should have a landing page."
"I would like for them to make this solution compatible with Mac OS. I would also like for them to provide a portal so that users can easily integrate it with their applications."
"Fast user switching and Citrix integration in Imprivata OneSign could improve. There are many options available for VDI connectivity, but I've seen issues with VDI connectivity and Citrix storefront connectivity."
 

Pricing and Cost Advice

"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."
"It falls in line with everything else."
"During testing we are allowed a certain number of licenses for free."
"From a business perspective, it is a little bit costly. The licensing is on a per-user basis."
"Overall, the pricing is fair. Customers can wrap it into their Enterprise Agreement, making it easier for them to solve their issues."
"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."
"The product’s pricing is reasonable."
"The pricing was a lot more than what we were paying for our previous solution."
"I would rate the pricing a four out of ten, where one is cheap, and ten is expensive. It is not that costly. It is cheap, easy to manage, easy to install, and easy to configure."
"The pricing is fair."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"The product has affordable pricing compared to other vendors."
"I price of the solution is expensive."
"I rate its pricing a three to five out of ten."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"Between paying them to help with the configuration, the box itself, and the support, it came to like $12,500, including a three-year service agreement."
"At the moment, I believe the price is reasonable."
"The price is reasonable, it's an affordable solution."
