The thing that I like the most is that they're very willing to work with us to resolve issues that they haven't taken care of before in their product.
The end-user protection suite is very good, including the log analysis feature that they now have.
There should be integration with Microsoft Azure active directory. The rules base for data center access must correlate with the group membership of the users to be granted access to systems and services.
We have used the Fortigate solution for 2 years and the Forticlient is soon to be rolled out to our mobile users.
Fortinet FortiGate-VM is very stable.
The technical support is very good.
We previously used CheckPoint. Though a good solution, the license costs became too high for our organization and obliged us to look for another option.
Be very clear with your security consultant who is proposing Fortinet as a solution regarding all the features and integrations you expect to achieve with the solution.
Yes, we reviewed Palo Alto, Barracuda, and Sophos
Overall, on a scale from one to ten, I would give this solution a rating of eight.
