Firewall:  

The firewall is configurable to block any ports the user specifies. In addition, other ports can be opened permanently or opened or closed on a scheduled basis. The firewall does a good job at keeping unwanted attacks out of your network. The firewall doesn’t put a noticeable drain on system resources either.

The Symantec firewall is rule-based and takes advantage of generic exploit blocking to stop malware before it even reaches your computers. Symantec also includes an IPS (intrusion prevention system) to stop invaders and hackers from compromising your systems.

Antivirus:  

Symantec is the only company to have received 41 consecutive VB100 awards, so you know they know a thing or two when it comes to viruses. With the device control feature you can control which peripherals can be connected to a machine. Terminals can be locked down to prevent connections from thumb drives and other USB devices. It even protects from viruses spread on external devices like CD burners, printers, mp3 players, and other USB devices. This can keep sensitive information from being stolen or transmitted and keeps viruses from spreading throughout the network. Administrators can even control applications at the workstation level, enabling or restricting users from specific applications.

With new threats engineered to bypass traditional security software, heuristic detection is more important than ever. The proactive threat scanning helps keep your systems safe from even new viruses. TruScan scores both the good and bad behavior of unknown applications, resulting in more accurate malware prevention. This can help to detect malware without the need to setup custom rules and configurations while also lowering the number of false positives.
