The most helpful aspect of this software is that it allows for multiple users access at once without having each user have their own login credentials or password (which can be tricky).
Sometimes I'll get an error message saying "Stack Armor could not authenticate" but then after refreshing my browser will load normally again so no problem there! If i had any complaints about Stack armor they would probably just fall under general dislike/frustration - which doesn't really matter because its great overall though!! We use stacksarmor as our main security platform allowing us easy management between all 3 platforms we utilize; SCCM & Security Center Manager(SC) w / MS Exchange End Point Protection + Mimecast VPN Client.
