Complete Anonymous Internet is a utility to let you hide your IP address when browsing the web, sending email, posting to usenet news groups, downloading via FTP and all other internet (TCP/IP) related programs. Furthermore by redirecting the incoming TCP/IP traffic through a SOCKS proxy, corporate networks won't need to install internet security software (antivirus, firewall, antitrojan, web content filters, etc.) on every single computer. Instead all security software will be installed on SOCKS proxy only, where the incoming traffic will be scanned and only safe content will be sent to corporate network.
