Anonymizing proxies allow the user to hide their web browsing activity. They are often used to bypass web security filters, for example to access blocked sites from a work computer.
Anonymizing proxies hold significant risks for organisations:
- Security – The anonymizing proxy bypasses web security and allows users to access infected web pages
- Liability – Organisations can be legally liable if their computers are used to view pornography, hate material or to incite illegal behaviour. There are also ramifications if users violate third-party licences through illegal MP3, film and software downloads
- Productivity – Anonymizing proxies can enable users to visit sites that, although safe are often used for non-work purposes.
