Featured Reviews

Francesco Panacea - PeerSpot reviewer
Senior Consultant at Deloitte Risk Advisory
Offers a reliable platform for securing administrative access and reduces cloud maintenance overhead
I have not found many drawbacks in Delinea Authentication Service, but perhaps they could focus more on the development of the platform for all of the products. I mean, rather than having Secret Server and Privilege Manager as silos, they could have a unique platform. In future updates of this solution, I would like to see features that other PAM vendors are adding, such as machine identities, AI, agentic security, and perhaps certificate security for Delinea. Delinea integrates with third-party tools by having some out-of-the-box connectors, but not for all. Adding more connectors could be an evolution for the next product. Responsiveness could be another area of improvement. They are pretty much slow to respond or perhaps I don't get the answers I want.

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.

Quotes from Members

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

Pros

"The best feature of Delinea Authentication Service, in my opinion, is that Delinea is a leader in the Gartner Magic Quadrant for PAM solutions, particularly with Secret Server, which we used, and also the Privilege Manager."
"This is a cost effective and flexible solution."
"The product is stable and reliable."
"The integration into tools, including CI/CD pipelines, is easy and handy."
"The most valuable features are the performance and ease of use."
"FortiAuthenticator centralizes the management and storage of user identity information, thereby increasing the efficiency of administration and increasing the control over who accesses the network."
"Once you configure it properly, it runs fine."
"The web feature is quite versatile. It serves as the sole server authenticator and is valuable not only with FortiGate products but also within the entire Forti system, making it highly useful for me."
"The technical support for FortiAuthenticator is excellent."
 

Cons

"Responsiveness could be another area of improvement. They are pretty much slow to respond or perhaps I don't get the answers I want."
"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."
"Integration with FortiGate could be more fluid."
"I have had stability issues with FortiAuthenticator."
"The price of the solution could improve, it is expensive."
"The one thing they used to include was the SMS gateway from the ISP; Fortinet used to sell that but they don't anymore and I think it would be helpful for end-users if they brought it back."
"The interface is a bit misleading in areas."
"One of our clients has faced a lot of issues with FortiAuthenticator. For example, one of the devices restarted by itself, and the database was corrupted."
"If two-factor authentication is needed also for the end-devices, for example endpoints or servers, I think FortiAuthenticator is not yet the most mature solution."
 

Pricing and Cost Advice

Information not available
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"I rate its pricing a three to five out of ten."
"It costs more to license the high-availability option."
"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."
"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."
"I rate the price of Fortinet FortiAuthenticator a three out of five."
"The pricing is fair."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
