Room For Improvement

Fortinet FortiAuthenticator needs interface updates, better documentation, improved integration, scalability, automation, and support with attention to pricing.
Active Directory needs a user-friendly interface, better integration, security upgrades, and improved cloud synchronization for enhanced usability.
For example, authentication for wireless users expires after 24 hours, requiring re-authentication daily.
I recommend Fortinet make its images migratable between environments.
I would like to see more integration and inclusion of features for ransomware protection directly within the FortiAuthenticator without requiring additional devices.
The current Active Directory UI is limited in report generation, necessitating script knowledge to generate various reports.
Sometimes, it can be overly complicated, and when you apply Group Policy in an Active Directory environment, sometimes those settings apply and sometimes they don't.
There are some features that need improvements in terms of ease of use and frequency of updates.
 

Setup Cost

Fortinet FortiAuthenticator offers flexible, competitive licensing with optional costs, balancing features and market conditions effectively for affordability.
Microsoft Active Directory offers affordable licensing, often bundled, with Azure cloud reducing costs by eliminating server fees.
Fortinet FortiAuthenticator is not overly expensive compared to other Fortinet subscriptions.

I can control all the devices in my domain by just changing the group policies in one place.
If I change a password or need to reset a password, the information propagates relatively quickly, and the structuring inside is easy to understand and use.
