The place where i work has a few people who have laptops and PDAs. We have antivirus, firewall, etc when you are connected to the network. What we are looking for is a software for these portable devices that will scan for viruses and stuff before they connect to our network via VPN or other means. Once they connect our virus scan will take over but we are trying to get an extra level of protection so that they will be detected beforehand. Any suggestions on software? I have come across a few different things but am not sure what to go with. I appreciate any help you can give me.
