One site we worked on had something like 10 firewalls in different branches, and the security admin there needed to monitor the firewalls from a centralized place, so we deployed FortiManager and configured it so he could monitor things from one place.
At another site, we use it in backup mode for automatic backup.
The product is a combination of management and monitoring from the same interface.
The areas that need improvement are implementation and support. In terms of implementation, it mainly needs clear documentation. There are many features that are not mentioned in the documentation.
We've been using FortiManager for almost one year. On some sites we use the latest version, and for other sites we use version 6.4.
We have done implementations of a number of Fortinet products such as Email and FortiWeb firewalls. We have implemented the portfolio of Fortinet products.
For FortiManager, technical support is good, but it's not excellent. It's not perfect because there are times when it takes longer for them to reply to cases. And, as I mentioned, sometimes we can't find a feature in the documentation.
It's easy to install and it takes about two days.
I recommend FortiManager if you have more than FortiGate firewalls or more Fortinet products.
In terms of users of the solution, our clients are between medium and enterprise in scope.
