Businesses and individuals use proxy servers for a variety of reasons.
1.Controlling employee and Child Internet Access: Organizations and parents set up proxy servers to control and monitor how their employees or children use the Internet. Most businesses don't want you to visit a particular site during company time, they can configure proxy servers to deny access to a particular site, and instead redefine it for you with a nice comment. They can also monitor and log all Web requests so that even if they can't block the site, they know how much time you spend on the network.
2.Bandwidth savings and speed improvements: Organizations can also get better overall network performance with good proxy servers. Proxy servers can cache popular web sites (keeping copies of them locally), so when you request www.varonis.com, the proxy server checks to see if it has the most recent copy of the site, and then sends you the saved copy. That is, when hundreds of people access www.varonis.com from the same proxy server at the same time, the proxy server only sends requests to varonis.com. This saves your company bandwidth and improves network performance.
3. 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 network requests. That said, the target server doesn't know who actually made the original request, which helps keep your personal information and browsing habits more private.
4. Enhanced security: Proxy servers provide security advantages in privacy. You can configure your proxy server to encrypt your network requests and prevent your transactions from being eavesdropped. You can also block access to any known malware sites through proxy servers. In addition, businesses can combine their proxy servers with virtual private networks (VPNS) so that remote users always access the Internet through corporate agents. A VPN is an enterprise network that companies use to connect directly to external or remote users. With VPNS, companies can control and verify that their users have access to the resources they need (Email, internal data), while providing secure connections for users to protect company data.
Access to blocked resources: Proxy servers allow users to bypass content restrictions imposed by companies or governments. Did the local sports team lose power online? Log into a proxy server on the other side of the country and watch from there. Your proxy server makes it look like you live in California, but you actually live in North Carolina. Governments around the world closely monitor and restrict Internet access, and proxy servers provide their citizens with access to the uncensored Internet.
