Web Security Appliance Overview
The Web Security appliance is a robust, secure, efficient device that protects corporate networks against 
web-based malware and spyware programs that can compromise corporate security and expose 
intellectual property. The Web Security appliance includes protection for standard communication 
protocols, such as HTTP, HTTPS, and FTP. 
Malware (“malicious software”) is software designed to infiltrate or damage a computer system without 
the owner’s consent. It can be any kind of hostile, intrusive, or annoying software or program code. 
Web-based malware includes spyware, system monitors, adware, phishing and pharming techniques, 
keystroke (key) loggers, browser hijackers, trojan horses, and more.
Web-based malware is a rapidly growing threat, responsible for significant corporate downtime, 
productivity losses and major strains on IT resources. Additionally, companies run the risk of violating 
compliance and data privacy regulations if their networks become compromised by malware. Companies 
run the risk of expensive legal costs and exposure of intellectual property.
The best place to stop these threats from entering the network is right at the gateway. The Web Security 
appliance provides deep application content inspection, by offering a web proxy service and by 
monitoring layer 4 traffic. The Web Proxy and Layer 4 Traffic Monitor allow organizations to ensure 
breadth of coverage within their networks. The Web Security appliance provides a powerful web security 
platform to protect your organization against malware that is optimized for performance and efficacy.
