  • You desire extra security from online bad guys and identity thieves
  • You don't want your Internet Service Provider, or owner of a network you're connecting through, to log, monitor, and/or control what you do online
  • You want to hide your IP address so you can protect your identity and location
  • You don't want search engines, such as Google, Yahoo, AOL, and Bing recording and storing every Internet search you perform -- potentially forever
  • You use Wi-Fi Hotspots
  • You have a company-issued VPN but don't wish to use it for personal business
  • You use the Internet at hotels or other shared hospitality or public networks
  • You live in, or are visiting, a country that blocks Skype, Facebook, Twitter, or other Internet services
  • You live in, or are visiting, a country that engages in Internet censorship or monitoring of content
