You'll need a VPN in the following instances:
1. Changing your IP address to the VPN server's IP address.
2. Visiting websites and launching apps blocked by your Internet Service Provider.
3. Willing to conceal from your Internet Service Provider a fact of visiting certain websites. VPN provides anonymous access to websites and apps - your Internet Service Provider is only notified of you being connected to a VPN - all the web-traffic is encrypted with a 1024-bit key.
5. Connecting to open Wi-Fi networks (password-less). All the data in these networks is transmitted in the clear (without encryption). If a website doesn't feature an SSL, then all the information that you submit on this website may be intercepted by ill-intentioned persons. VPN encrypts traffic and prevents it from being read even in case of open Wi-Fi networks.
