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."
"I really like the two-step authentication, it provides a higher level of security that we didn't have previously."
"FortiAuthenticator is easy to use."
"This is a scalable product."
"This is a very important product if a company wants to use a VPN."
"The solution is simple to deploy, simple to use, and user-friendly."
"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 solution is easy to learn and makes it easy for our users to add FortiToken, and it's very easy to integrate if you have other Fortinet devices."
"The first valuable feature is being able to see everything on one platform. This includes logs and authentication failure."
 

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 technical support could be improved as some staff lacks the necessary knowledge to assist effectively."
"The GUI has some shortcomings and can be made better. The GUI is not great."
"Fortinet FortiAuthenticator's initial setup process could be easier."
"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"We've had some issues with integration."
"It does not consider customer requirements."
"The support team is pathetic and does not properly understand the solution."
"The hardware aspect of the solution could be improved. We are not really able to understand the hardware capabilities of the device."
 

Pricing and Cost Advice

Information not available
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"We pay for licensing on a yearly basis."
"It's not expensive."
"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."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
