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

"Cisco Duo has helped my organization reduce its overall authentication-related costs."
"The deployment and installation process for Cisco Duo is quite straightforward, which is an advantage."
"Duo is a very consistent product and flexible in how it can be deployed and has good support."
"Cisco Duo has strengthened the ability to defend against both phishing and identity-based attacks."
"The two-factor authentication is valuable because that is the use case for which we are using 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."
"Right now, I do not think there is anything about Cisco Duo that I would improve; I have been happy with everything so far."
"At the moment, the ease of use is what is the best feature for me. Once it has been set up and the security can hoc to my mobile device, it's very simple to use my single sign-on, get prompted for a Duo Security, push, go to my phone, accept the push, and I'm done. It's a very simple process."
"Technical support is excellent with Fortinet FortiAuthenticator."
"Enables easy integration, allowing for 2FA with our VPN."
"This is a very important product if a company wants to use a VPN."
"The ease of use is really nice. Using Authenticator, I've been able to actually work better on my authentication due to the fact that I have a single fabric to authenticate control from my firewall and on my access points. Authentication takes place from this area."
"The product's initial setup phase was easy. It is also easy to deploy."
"I really like the two-step authentication, it provides a higher level of security that we didn't have previously."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"In my opinion, the main benefits that end users receive from Fortinet FortiAuthenticator include more security for their applications, for their systems, and for all their network devices that they are logging into."
"Imprivata OneSign helps customers minimize their work in remembering passwords and enhances their security."
"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."
"I have seen many benefits from using Imprivata OneSign. It saves substantial time for nurses."
"It has benefited my organization in the way that it makes it more secure by making it harder to hack."
 

Cons

"The only challenge is finding the right person sometimes. From what I've seen, being a named account is a big deal."
"We have had instances where Duo Security stops working on a user's device, which we have fixed by uninstalling and then reinstalling it."
"They can make authentication easier. It should be done in a shorter time. Sometimes, it can take a bit more time to get the answer on your phone. You have to wait a bit longer to get the SMS code and other things. There can be some internet or connection issues. They should make it faster because sometimes, it's urgent, and you need to access something as soon as possible."
"Cisco Duo is stable, but occasionally there are emails about incidents that affect some services temporarily."
"Most of my colleagues from other companies use the Microsoft MFA solution because it's included in Office 365. Few people are considering Cisco Duo. That's the primary problem in our area. It's a solution mostly adopted by Cisco users."
"The only thing I can think of to improve for tech support is to have a dedicated engineer but then I would get an engineer that has priorities in one area or another and maybe not the scope I need."
"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."
"Cisco Duo is definitely not doing things that others are not doing, so there is no unique selling proposition."
"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."
"The integration with third-party tools must be better."
"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"Initially, we deployed Fortinet FortiAuthenticator on VMware and faced challenges when migrating to an OpenStack environment, which required reconfiguration. I recommend Fortinet make its images migratable between environments."
"A lot of configurations are available only from CLI."
"FortiAuthenticator's interface could be better."
"FortiAuthenticator should integrate with other applications."
"There have been numerous support tickets sent to Fortinet since this does not appear to be a mature product."
"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."
"Imprivata OneSign should have a landing page because most customers prefer this feature, which is currently a strong point for competitors."
"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 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."
"Cisco has the most expensive products because market leaders tend to charge a lot."
"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."
"Duo Security's pricing is good, fair, and very comparable to today's market."
"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."
"Our licensing fee is currently on an annual basis."
"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."
"I rate its pricing a three to five out of ten."
"I price of the solution is expensive."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"It costs more to license the high-availability option."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"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."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"At the moment, I believe the price is reasonable."
"The price is reasonable, it's an affordable solution."
