SaferSurf
SaferSurf is a software product for anonymous internet surfing. Aside from offering web anonymity, it has several other features, such as a geolocation proxy service bypassing country restrictions. Its slogan is "Tearing Down Country Borders in the Web". SaferSurf runs centrally on a server and doesn't need a local installation.
SaferSurf was created and developed by a team from Nutzwerk, a German software company headquartered in Leipzig developing internet technologies.
It obtained the TÜV certification in 2005, 2006, 2007, 2008 and 2009. It was tested for a wide range of viruses and false alarms.
