Effective protection - blocks the most common hacker network attacks by continuously F-i-l-t-e-ring incoming and outgoing traffic. Tracking network activity - contains predefined rules for the most commonly used mail transfer agents, web-browsers, ICQ and other instant messaging programs. Packet filtration - checks all data packets and prevents unsanctioned leaks of confidential information. Self-modification system - modifies security rules for Internet applications using its inbuilt self-modification feature. Total invisibility - SmartStealth technology protects you by making your PC 'invisible'. When your computer is in 'Stealth' mode, no one can detect your computer in a network since all network activity is prohibited, unless explicitly permitted by rules which you, the user, define.
