It's a Virtual Private Network. And a proxy and VPN are two totally different animals. I trust NO free online proxies. They are wide open for packet sniffing, and they are horrible for lag. A VPN is way more secure as it encrypts your packets rather than encipher them. If you need to use a proxy or VPN, pay for one. The most secure and fastest that I know of is fixmylag. 5 bucks a month, and their latency is about 50% less than what everyone else is. Free isn't always the best.
