(No system kernel Amaranten firewall is a systemless kernel, that is, the firewall does not have an operating system, so there will be no loopholes in the general operating system, so as to ensure the security of the firewall at the bottom layer; Upgrade, there is no such problem without an operating system, which also excludes the problem of damage to the firewall function and function due to system upgrade and patching. After the Amaranten firewall kernel is started, it can directly manage all the hardware of the firewall (CPU, network card, bus, etc.), it can take over and manage the incoming and outgoing firewall data from the hardware device at the bottom layer, and utilize all possible hardware functions. Reduced operating system overhead and thus the fastest management of data, making it one of the fastest firewalls available in the field)
