Smaller schools can really benefit from low cost hosted firewall options, if you are using a less than 300 Mbps connection the cost can be good value. Not always as many features as on premises firewalls, sometimes less reports and stats but the important stuff is there. This may take your Smoothwall costs down if you have a renewal cost for Filter and Firewall and if you do have a Smoothwall appliance on site it may reduce the CPU load if its just in Filter mode. Many of our smaller schools will just have our managed router on site, hosted firewall and then a per user cost for Smoothwall Filter and then add if required Smoothwall Monitor.
