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 extends IronPort’s 
SMTP security applications to include 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.
