Privatefirewall integrated desktop firewall and multi-layer intrusion prevention software delivers signature-less, zero-hour protection from known or new spyware, keyloggers, viruses, hacking techniques and other intrusions on Windows desktops and servers. Privatefirewall is comprised of several distinct protection layers including desktop firewall, port manager, URL filtering, process monitor, anti-logger, and application/system behavior modeling and anomaly detection components. Privatefirewall evaluates WinAPI calls and analyzes a comprehensive list of system variables and security-sensitive registry keys and alerts administrators to possible malware, attack, or policy violations. Privatefirewall?s layered approach to PC and enterprise endpoint defense addresses the Windows vulnerabilities that hackers exploit to gain unauthorized system access and cause damage to private systems and data. Privatefirewall models and monitors system behavior to identify and block activity characteristic of known malware, hacking, phishing and other threat types so that personal computer users and IT managers within small, medium or large organizations can more effectively and proactively protect the environments and private data for which they are responsible. Internet and network security settings, untrusted web sites and IPs, and the manner in which software applications and related processes can access the Internet can be easily configured via Privatefirewall?s intuitive management console. Privatefirewall is absolutely free of charge for personal or business use and supports Windows 8/8.1 (32 and 64 bit), Windows 7 (32 and 64 bit), Vista (32 and 64 bit), Server 2008/R2 (32 and 64 bit), Server 2003 (32 bit) and Windows XP (32 bit).
