I just installed it on my work laptop a couple of days ago and it is working well. I have a desktop and laptop that have been finicky with ZA free and Filseclab. So I ran Jetico for a while on the laptop, am still trying it at home but switched the laptop to the latest Kerio 4.2.2 It is really, really user friendly, maybe easier than ZA. Certainly easier than Jetico. What are your observations, opinions, experiences with it? Is it stable? Is it secure? Is it heavy on resources?
