In today's business environment organizations rely on the Internet for access to information and resources. While instant access to information over the Internet is critical, it introduces incredible risks to the network and data. Every day new threats such as viruses, worms, Trojans, phishing attacks and spyware programs cause serious financial damage to companies through compromised computing systems, lost productivity and the theft of passwords and other confidential information. The opportunity to connect to Web sites that contain objectionable or even illegal content can leave organizations vulnerable to legal liabilities and unwanted security risks. Additionally, the use of instant messaging (IM) and peer-to-peer (P2P) applications compete for employees' time and can result in tremendous losses in productivity.
