Sitting on the perimeter of your network, a firewall is your outermost defence from threats both entering and leaving your systems. By acting as a constant watch, your firewall will automatically block and report on suspicious activity, allowing you to act before a threat can take hold and become damaging. Firewalls can take the form of either a physical hardware device or as software installed on a server appliance. There are many different options available, so it is always advisable to seek expert advice when procuring the right technical cyber defences for your organisation.
