Virtual Private Networks (VPNs) have become an indispensable tool for many internet users in order to:

- Protect their privacy and anonymity on the internet
- To secure their internet connection when using public Wi-Fi networks
- To access overseas websites and web services such as Netflix, Home Box Office and streamed broadcasts of major sporting events that may be blocked to them by geographical restriction
- To use BitTorrent and P2P networks anonymously without disclosing their real IP address
- To bypass national firewalls operated by restrictive regimes that block access to sites like Facebook and Google.
