After 10 years in the business, Anonymizer has two million active users. The US government pays it to promote the service in China and Iran in order to help promote free speech.
But these programs are becoming popular in the West too.
The software encrypts all your requests for webpages. Anonymizer’s servers then automatically gather the content on your behalf and send it back to you.
No humans are involved and the company does not keep records of who requests what.
However, there is some censorship. Anonymizer does not support anonymous uploading to the web, and it blocks access to material that would be illegal under US law.
