1. Control staff and children's Internet Use: Organizations and parents set up proxy servers to control and monitor how their staff or children use the Internet. Most organizations don't want you to view specific sites on company time, and they can configure proxy servers to deny access to specific sites, instead redirecting you with a nice comment asking you not to view said sites on the company network. They can also monitor and log all web requests, so even though they might not block the site, they know how much time you're loitering on the web.
2. Privacy Advantage: Proxy servers are used by individuals and organizations to browse the Internet more privately. Some proxy servers change the IP address and other identifying information contained in Web requests. This means that the target server doesn't know who actually made the original request, which helps make your personal information and browsing habits more private.
3. Enhanced security: Proxy servers provide security advantages on top of privacy advantages. You can configure your proxy server to encrypt your network requests to prevent snooping on your transactions. You can also prevent known malware sites from making any access through proxy servers. In addition, organizations can combine their proxy servers with virtual private networks (VPNS), so remote users can always access the Internet through corporate proxies. A VPN is a direct connection that a company provides to external or remote users to the company network. By using VPNS, companies can control and verify that their users have access to the resources they need (email, internal data), while also providing users with secure connections to protect company data.
4. Access to blocked resources: Proxy servers allow users to circumvent content restrictions imposed by companies or governments. Are the local sports teams off the Internet? Log in to a proxy server on the other side of the country and watch from there. The proxy server makes it look like you're in California, but you actually live in North Carolina. Several governments around the world closely monitor and restrict access to the Internet, and proxy servers provide their citizens with access to the uncensored Internet.
