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.

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.

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."
"It is used for SSO, single sign-on, and as a captive portal."
"This is a scalable product."
"Enables easy integration, allowing for 2FA with our VPN."
"For someone concerned with multifactor authentication, I'm satisfied with the product."
"The solution is very easy to manage."
"The most valuable features are the performance and ease of use."
"The technical support for FortiAuthenticator is excellent."
"The most valuable feature is the OTP on the mobile phone."
 

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."
"I think the tool could provide this solution on the cloud. It's currently an on-premises solution. A cloud-based version could make setup, installation, and management easier. With on-premises, you must pay capital expenses (CapEx) upfront. However, if the solution was cloud-based, it would be operational expenses (OpEx), which is often easier to manage. You can pay monthly instead of paying the total cost at once. In my opinion, OpEx is more easily manageable than CapEx."
"I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices."
"There have been numerous support tickets sent to Fortinet since this does not appear to be a mature product."
"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."
"I would like to see more security features in reference to identity login or identity identification."
"The only way the solution could be improved is if it were cheaper."
"FortiAuthenticator's interface could be better."
"Lacks a simplified two-factor authentication process."
 

Pricing and Cost Advice

Information not available
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"The solution is not very expensive."
"We pay for licensing on a yearly basis."
"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 rate the pricing a four out of ten, where one is cheap, and ten is expensive. It is not that costly. It is cheap, easy to manage, easy to install, and easy to configure."
"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."
