Using VPN/HTTP tools you can protect not only your IP address, but encrypt the entire data traffic. Does it sound good, right?
First of all, to VPN: VPN stands for Virtual Private Network and it is, as the name implies, a private network. Therefore, it is treated as every local network, but it only exists virtually.
For example: If you are, for example, a student and you want to access internal data at your university, you need to log in via VPN only, as for example your professor allows access to certain lecture notes from the IPs of your university only. So you take a so-called VPN client and must authenticate yourself, ie prove that you are an authorized user of the service.
For the most part this data is controlled via username and password. Since we are dealing with sensitive data, the VPN connection is encrypted. Therefore, the data packets are encrypted (SSL) and delivery over the Internet as SSL blocks of information. When you join the VPN, you are recognized as part of the network, and you can access the site of your professor just as every user on this network.
As for the proxies: proxy is really a kind of a messenger, with the messages being send out and back. If you use a proxy to forward all your requests, the frequently accessed data is stored in cache, so that pages are loaded faster.
For example: If you call example.com, your request will be sent to the proxy, which acts as a middleman between you and example.com, sending data back and forth. You know that the proxy is in-between connection, but example.com «thinks» that it communicates with the proxy only.
Therefore, it is important to understand that proxy sites do not guarante anonymity or security, whereas VPN, however, requires an encrypted connection so that the data can not be intercepted and read by the third parties.
While VPNs are considered ideal way for anonymous surfing, they also are said to be too complicated and too expensive. Can you forget it? At least if you want to use a VPN in Firefox, use ZenMate and everything will be fine. There is no traffic limit and the handling is very easy. Just click on the icon, select the desired location and start surfing via VPN.
More than just Proxies
In simple proxy and VPNs scenarios one is actually have to go with a different IP address, so that the tracing is not simple, yet possible. The situation is different in proxy cascade, ie when multiple cascaded proxies are used.
In order to surf the web anonymously, it is a good idea to deploy «multiple cascaded» scenarios. Gate is the best possible example of this type of anonymity surfing. Anyone who wants to use Tor Network can use the Tor Browser Bundle.
But this kind of anonymity has its drawbacks: In practice, the decisive argument against the gate is that the surfing speed falls off dramatically. A compromise can be reached by using Tor Button extension on Firefox. Alternatively, you can install and run Tor Browser.
JonDoFox: Speed for cash
An alternative to the gate technology is based on Firefox extension named JonDoFox. It integrates seamlessly with multiple proxies, thus ensuring anonymity while surfing the Internet. But here is the problem you might face – it is high traffic caused by the anonymization techniques.
Hence, the free version of the service offers very slow connection, limited to a maximum of 50 kilobits per second. It is unlikely you want to surf the net that fast. If only you buy premium access, you get the full speed. Strings attached: Even with highest rate possible (100 € for 6 months) the volume of data is limited to 5 GB per month. Hence, it is up to you budget and needs how to use VPN/HTTP Proxy.
