Virtual private networks have many uses. Typically, businesses deploy VPNs so employees can securely access the corporate network from outside the office. However, we’ve seen a rise in third-party VPN services that use the same underlying technology, the encrypted tunnel, to simply provide a secure Internet connection.
Why would you ever need to do this?
When connected to a VPN service, the websites you access think you’re at the location where the VPN server is located. This can help anonymize your Internet traffic so it’s much harder for websites to track your personal browsing history.
This also allows you to access websites, services, and content that’s restricted where you are currently located, such as Netflix or Hulu when traveling overseas.
