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.
Sachin Vinay - PeerSpot reviewer

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:

Cons

"The interface is a bit misleading in areas."
"The GUI has some shortcomings and can be made better. The GUI is not great."
