A proxy server is computer hardware that functions as a security intermediary between an operating system and the Internet. Generally, network administrators establish a proxy server by utilizing Internet filtering software like Websense, Barracuda and McAfee to restrict access to websites that are considered harmful, display inappropriate content or take up too much bandwidth. However, it isn’t uncommon for harmless and useful websites to become restricted by a proxy server. Fortunately, if you need to access a blocked website, you can get past a proxy server by using a proxy site, which allows you to bypass any Internet restrictions anonymously and securely. Writer Bio
