Kerio Personal Firewall (KPF) protects connected PCs from Internet threats. KPF inspects both incoming and outgoing connections ensuring that only legitimate traffic is allowed. MD5 signatures are assigned to all applications to prevent Trojan horses from posing as a trusted application. Kernel monitoring prohibits installation of potentially dangerous kernel drivers that may bypass the firewall inspection. KPF offers a remote administration, logging of suspicious activities, open connections overview and automated update checker.
