From a security perspective, FortiWAN needs to be improved. The data in FortiWAN is not secure because they are not upgrading to the latest technology, whereas the OEMs are upgrading day by day.

More needs to be done with engineering frameworks, such as aggregation.

When we add a lot of rules, perhaps 100,000 to 200,000, the bootup process is very slow.

Technical support has room for improvement.

Having more documentation would be helpful.
