@CySecy825 They have their own engine and web filtering service. No engines from other vendors are used. Everything is made and scanned by fortinet themselves. It's a quite underrated product. The only thing it lacks is a zero day component, but in combination with something else, its very solid. So you see that it can be done without Bitdefender engine
Very good performance from Forticlient.
As for zero day protection i think we can pare it with Comodo Firewall and Comodo Sandbox will protects just fine.
Thank you @safe1st for the test
