The most important thing i like about this product is its availability of many features which are very essential at present times so it has become quite popular amongst clients who need security but without affecting their productivity or working styles. It does require some technical knowhow as well because if you don't have expertise then there might be issues regarding server management/monitoring etc., I am solving my problem by running servers remotely from home through VPN connection using remote desktop software such RDC (realvnc).
