Yonas Abebe - PeerSpot reviewer
Integration capabilities simplify authentication and migration challenges need addressing
The integration capabilities of Fortinet FortiAuthenticator are very interesting, as it can be integrated with third-party devices easily and is straightforward to configure. The integration with FortiToken is outstanding, adding a layer of security for authentication. In addition, it can be used by integrating with zero trust single access, enhancing overall security measures.
IS
Positive impact on password management through AI-powered single sign-on
The best features of Imprivata OneSign include the single sign-on with its own AI, meaning that customers don't have to modify their coding. The AI remembers the password and login, so when users enter the system, the AI will input the login and password automatically. The beauty of Imprivata OneSign is that it can use single sign-on with legacy systems such as mainframe terminal products. Most of the latest single sign-on solutions cannot use mainframe systems. Imprivata OneSign helps customers minimize their work in remembering passwords and enhances their security.

Pros

"The most valuable features are the performance and ease of use."
"The most valuable feature of the solution is RADIUS service and the social network integration feature."
"We are using Fortinet FortiAuthenticator to implement token-based authentication for wireless network access."
"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"The integration into tools, including CI/CD pipelines, is easy and handy."
"It reduces the need for network administrator intervention by allowing the user to perform their own registration and resolve their own password problems and issues."
"The product’s most valuable feature is integration with FortiGate, FortiToken, FortiTalk, and multi-factor authentication."

"Imprivata OneSign helps customers minimize their work in remembering passwords and enhances their security."
 

Cons

"FortiAuthenticator's interface could be better."
"The solution could be more automated. It should be able to let me automate a lot of things so that what normally is done as a matter of manual processes can be handled quicker. Slow integrations can be taken up/out if there was more automation."
"There is a room for improvement. The log is a bit difficult to access, and searching the log codes is also a bit difficult. So it would be much better if, when we open a log, it could provide detailed information about errors, reasons for failure, and such."
"They could expand FortiAuthenticator's capabilities to accommodate a broader range of environments."
"The user interface and clustering are areas with shortcomings that need improvement."
"No SMS gateway from the ISP"
"The GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated."
"The solution's command line interface could be improved to provide better support for low-level debugging and advanced configurations."
"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."
 

Pricing and Cost Advice

"The solution is not very expensive."
"It's not expensive."
"On a scale of one to ten, where one is a high price and ten is a low price, I rate the pricing a seven."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"It costs more to license the high-availability option."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
