Sygate Personal Firewall Pro has redefined the personal firewall market with a multi-layered shield of network, content, application, and operating system security. It protects your system from intrusions designed to exploit vulnerabilities in Internet and Intranet communication. It is the ultimate desktop security solution trusted by professionals and relied upon by millions of users.

Features of Sygate Personal Firewall Pro 5.5 :

· Network Layer -- Secure Internet Connections
Halt Trojan Attacks
It is the first personal firewall that offers real protocol driver-level protection, preventing hostile programs such as Trojan Horses and malicious mobile code from accessing the network using their own protocol driver. With newly added network layer protection measures and existing application level protection, Sygate Personal Firewall Pro provides complete security from the network to the application layer.

· Content Layer -- Secure Trusted Traffic
Prevent Fraudulent Traffic
It is the first personal firewall with an application-based intrusion detection system (IDS). Network layer protection can ensure the inbound network packets are legitimate, but it can do little about the contents hiding in the packets. The high performance intrusion detection engine in Sygate Personal Firewall Pro monitors network traffic content, and uses pattern matching to detect a variety of attacks and probes, such as buffer overflows and stealth port scans.

· Application Layer -- Secure Component Integrity
Stop Application Hi-Jacking
It secures systems from intrusions that exploit vulnerabilities in applications to execute attacks. It verifies the integrity of every application that attempts to communicate through a fingerprint that includes a MD5 checksum. In addition to that, Sygate Personal Firewall Pro authenticates application dynamic link libraries (DLLs), preventing hostile programs that masquerade as authorized applications from compromising users’ data or system.

· Operating System Layer -- Secure Process Interactions
Secure System Start-up
It is the first personal firewall that integrates meaningful operating system layer protection, guarding the legitimacy of outbound traffic. It blocks any traffic generated before its own service starts up, eliminating the brief security policy vacuum. It can automatically terminate known attacks such as Trojans, Denial of Service (DoS) Zombies. Sygate Personal Firewall Pro also has defense mechanisms that prevent malicious code/and or users from disabling or exiting the personal firewall.

By building a multi-layered shield around a system, Sygate Personal Firewall Pro provides around-the-clock and multiplex protection for data integrity and system safety. No wonder it is the ultimate desktop security solution.
