The term "proxy" and "tunnel" shouldn't be used together. A proxy is not secure at all, and even if the term "tunnel" is attached to it does not change the fact that proxies are insecure, slow and unreliable.
If you are looking for a secure, fast, reliable and anonymous proxy to tunnel through, what you probably meant was a VPN Account. A VPN account is not only truly secure, fast and reliable but offers secure tunneling through all connections on your computer. Once you connect to our VPN Service, your entire system tunnels all traffic through our secure VPN automatically.
A VPN account is usually what someone looking for a secure proxy to tunnel through is actually looking for.
