Room For Improvement

When configuring it with third-party tools, like Active Directory, the naming convention of permission sets requires careful attention, which can be confusing.

Featured Reviews

Khaled Saidi - PeerSpot reviewer
Manage cloud security with granular access control and enhanced authentication
Managing IAM in complex environments can be challenging, and there are several areas for improvement. First, incorporating automation tools or a centralized dashboard for managing roles and policies across multiple accounts would simplify administration, especially for large organizations. Additionally, policy debugging and validation could be more streamlined, as troubleshooting misconfigurations can be time-consuming and prone to errors. A more robust error messaging system or a dedicated debugging tool would be beneficial. Another area for improvement is temporary access credentials. AWS documentation should offer more detailed guidance on edge cases and exceptions, along with clearer examples of how to handle various scenarios. Lastly, enhanced session-level policies that are more context-sensitive and based on specific conditions (such as IP address, device, or time) would greatly increase flexibility and allow for more granular control over user sessions.
Yonas Abebe - PeerSpot reviewer
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.
