This is incorrect. As of 5.6.1 the free version now includes Anti-Botnet, Dynamic Threat Detection and Anti-Exploit module. Observe this screenshot, showing a non-Fortigate linked free Forticlient with those modules available as checkboxes. For some reason your test had all of these disabled, I will check the default installer script, this is an oversight if they default to disabled. But you can easily enable them. (and everyone should) Also, I would like to provide you with a customized INI file to run your tests on. There are quite a number of advanced features I can enable in the INI. You'd just have to click a button to load my INI into your test client. With all of the modules properly enabled, and a test INI I have, I think the results might be surprising.
