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.

Supports secure remote authentication and provides comprehensive user activity tracking
The most important feature is the security capability because it provides a substantial amount of security for admin-related activities. Fortinet FortiAuthenticator can be used from anywhere in the world, and the authenticator services function globally. This global accessibility is one of the critical advantages, particularly since admin features are critical and security is a real concern. With Fortinet FortiAuthenticator, secure usage of firewall services and related functions is achieved. A complete log of all users who access the authenticator setup is maintained. Monthly logs are reviewed to check for any unnoticed activities. Each authenticated user's complete activity history is recorded. This logging capability allows for providing access to more admin users while ensuring security is not compromised and all users can be monitored.

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."
"The current version is stable...Scalability-wise, it is a fine solution"
"I prefer the passing tool that sent an active directory console to a Fortinet FortiAuthenticator, then Fortinet FortiAuthenticator does not pass the locks."
"It is very stable. We have never had any issues with this solution."
"The most valuable feature is the OTP on the mobile phone."
"The most important feature is the security capability because it provides a substantial amount of security for admin-related activities."
"Once you configure it properly, it runs fine."
"In terms of benefits, the tool provides both cost savings and efficiency, but efficiency is more important for our customers."
"The initial setup is very easy."
 

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."
"Fortinet FortiAuthenticator could benefit from some artificial intelligence functionality and resolution of some glitches that may exist."
"The user interface and clustering are areas with shortcomings that need improvement."
"The price of the solution could improve, it is expensive."
"The technical support could be improved as some staff lacks the necessary knowledge to assist effectively."
"The only way the solution could be improved is if it were cheaper."
"The product must provide 2FA for applications."
"Regarding Fortinet technical support, I would say a six. Most of the time, the engineer will take time, such as 24 hours or 48 hours, maybe even more, because most of the time, they appear, gather the logs, and then disappear."
"For improvement, Fortinet needs to ensure that they provide quick support to users...Fortinet sometimes needs to respond to users facing issues within an hour."
