Putting a firewall in the home office should be a natural thing to do. After all, you are not only protecting your user but also the data that they will be working on, and probably holding, on their machine. This security is just as important as the security in the main office, as liability on data and business-critical information could otherwise be breached with ease. This is where a small but powerful appliance from a developer with experience in both the enterprise and SOHO markets is going to come in very handy.
