There's a good article on accessing Facebook when it's blocked in China from CNN. We're mentioned as one of the options, in addition to a web proxy service. There are important differences between a VPN service like GoTrusted and a simple web proxy...
- Web proxies will be slower
- They may not fully support all web content - some web pages may not load or work properly. This isn't an issue with a full VPN like GoTrusted.
- Simple web proxies do not proxy other applications, just your web browser. GoTrusted will encrypt/proxy all applications automatically like Email, Instant Messaging, Video... pretty much anything that uses the Internet on your computer.
- Simple web proxies will not encrypt your data as a full VPN can - so what you browsing is still in the clear for your ISP or other users 'tapping' in to your connection.
