Privatefirewall may be considered as a good anti-theft and anti-intrusion solution mainly because it comes for free and enlists a sufficient package of security features. Moreover, this firewall integrates an application manager, port tracking, a process monitor and traffic filtering. According to everybody’s needs, users have the chance to configure their personal firewall profile. On the other hand, not so advanced users should avoid tweaking things out as they may block certain programs from connecting to the internet. This software runs on the basis of white lists and blacklists that grow considerably in time, given the feedback from the end-user. The Host Intrusion Prevention technology brought forward by this app is also available for servers.
