How does a VPN keep me secure?

How does a VPN keep me secure? A great question.

Let me simplify it for you.

A VPN uses servers to obfuscate (mask) your IP address and thus, protects you from the spying ISP, hackers, and other agencies.
A VPN creates a secure connection between you and the desired website.
A VPN encrypts your data with the latest grade encryption key so even if it is stolen somehow, it can’t be accessed easily.
A VPN relays your data across a different server so that your actual identity or data can’t be known.
I hope it helps.
