A firewall protects your network, but also controls a large part of the data on your network and all the data coming in and going out of the office. This data must be transparent and well protected. Moreover, this data must be prioritised in order to work well together. In addition, you need to make updates to keep security up to date with both the software and the settings. Securing one firewall is quite difficult, because it takes a lot of time. But if, like us, you manage more than a hundred, then it becomes easy.
