By definition, your services are always protected due to automatic mitigation, which activates as soon as an attack is detected (usually within a few seconds). By enabling permanent mitigation, you constantly apply a first level of filtering through our Shield hardware, as well as the filtering rules you have defined in the Firewall Network. Due to traffic always being routed through the firewalls, network speed may be noticeably slower. On the other hand, automatic mitigation will only route traffic to the firewalls when an attack is detected. In some cases, the detection may take a few seconds causing your server to go down during this moment. In this case, you may turn on permanent mitigation. Otherwise, it is recommended to let it off unless it’s really needed. You can toggle permanent mitigation on or off from the Control Panel.
