VPN services and Proxies
VPN services like Relakks, Steganos Anonym VPN, Perfect Privacy, Cyber Ghost VPN, XeroBank VPN, Linkideo, Ivacy...
JonDonym and Tor may be the best anonymization systems technically, but both share small restrictions from concept that should be considered when using them:
The combination of JonDo with a so-called VPN system (virtual private network) may slightly fix these restrictions: VPN software creates a single, encrypted connection to a certain VPN provider. This one accepts, similar to an access provider, your whole Internet data traffic (also the separately encrypted JonDonym data traffic), and forwards it to the Internet, while all users get the same exit IP address, similar to JonDonym.
Of course, this provider may thereby observe your whole Internet communication. Hence pay attention to choose a reputable VPN provider, in particular with a reputable company address and similar contact persons. If possible, you should also use a VPN software directly integrated in your Internet router instead of executing a VPN program on your own computer. Thereby the provider's software cannot harm your computer. In addition to that, active contents cannot read your real IP address any more. However, please note that active contents may still read a lot of data about your computer and network configuration.
For web surfing, VPN services should not be used.
Nevertheless, protection by the VPN of a professional and reputable host is often better than no protection at all.
Proxy services are particularly famous for this kind of "anonymization on demand", besides the already mentioned services. They are literally "proxy PCs" which switch communication between your PC and the Internet. They relay your data traffic to the target and send the answer back to your PC so that the web site cannot see your IP address.
Unfortunately, proxies have a high susceptibility to misuse and user data theft: many proxies are PCs hijacked by hackers or criminals, or even exclusively offered for the purpose of user observation. Some automatically give your IP address away to the target webserver. Connections with proxies are almost always unencrypted, so that an eavesdropper on your connection could observe your surfing behavior. Moreover, the proxy operator can, of course, watch exactly what you are doing. Proxies offer thus, if at all, only weak protection from the website's host but not from third parties. Their usage is risky.
In addition to these proxies, there are webproxy services, Internet pages with a form field in which the user can input the target address that he want's to visit anonymously. The webproxy subsequently delivers the content of the requested website and automatically patches all links to use the webproxy when clicked. For using webproxy services the browser configuration does not have to be changed.
