A proxy server can hide your identity from the websites you visit by "sitting between" you and your internet destination, passing data back and forth. However, many proxy sites claim to list "anonymous" or "elite" servers, when they really leak information about your computer-- compromising your anonymity. Many proxies unknowingly reveal your browser information and referring websites. Some of them even expose your real IP address!
ProxyGrader.com actually tests your proxy to find out how anonymous it is. You can submit your own proxy to be graded and view a report about its performance. First, we'll test that it is actually usable, and doesn't just give you an error or ask you for a password like proxies listed on other websites. Then we'll test the anonymity of the proxy, showing you exactly what information it leaks, and what information it keeps private!
Potential anonymity issues are rated according to severity to help you decide whether the proxy is secure enough for your purposes. Each ProxyGrader report details the server's speed, internet service provider, and geographical location. We also check whether the IP address is listed in major spam blacklists.
Use the form at the bottom of this page to submit a proxy for grading. You must provide the IP address, port number, and connection type of the server. We support the three most common connection methods-- HTTP, SOCKS4, and SOCKS5. The proxy will be tested instantly, and you will be taken to the results.
