Eztun System

All your Internet activities are under constant control. Every time you visit a website, chat with a friend, write an email or use a file hosting service, the ISP (Internet Service Provider) collects and stores your personal data.

This refers to the URLs (website's address), passwords, downloads content, and even IM logs in some cases. This data could be retrieved not only by your service provider, but actually by anyone who is computer literate enough. There is obviously no need to explain the consequences, right?
Eztun makes it possible to hide IP and surf the web without leaving any "traces" that could guide various hackers, spammers, and other net criminals right to your real IP address (read: your accounts, your data, your money and reputation). You also get an opportunity to change your IP (i.e. to choose a different country), which may be extremely useful in case you intend to use services that normally cannot be reached from your current location (e.g. closed websites, some file hosting services, location-oriented portals, etc.).
