Every LAN that has various PCs that share the Internet needs to use a proxy. But as a hardware element, proxies also need to be checked to make sure they`re working properly. And for this objective is a tool called Super Proxy Helper.
From Super Proxy Helper you can check the proxy, view its status, its response time, the type of proxy it is (if it works transparently, anonymously or highly anonymously), import/export the information, download a list or proxies directly from the web, change the properties of the proxy configuration, activate the security to preserve your privacy while you use it, etc.
