Even if a hacker manages to position himself in the middle of your connection they need to break through a layer of encryption. So we can say yes VPN protects you and your online activity on public wifi.

What is a VPN and how does it work?

VPN stands for Virtual Private Network, it creates a private network connection between devices on the internet. Using VPN you can browse the internet or transmit data anonymously and securely over a public network. VPN disguises the user’s Internet Protocol (IP) address, so your location and online activity remain hidden. Also encrypt all data so that it cannot be read by anyone who is not authorized to receive it.

By using VPN you can also bypass censorship, unlock website restrictions, and surf the internet from any part of the world through its remote servers.

  • VPNs are “virtual” because they are a digital service.
  • VPNs are “private” because they encrypt your connection and let you browse the internet anonymously.
  • VPNs are “networks” because they build a secure connection between your device, the VPN server, and the internet

A virtual private network (VPN) connection is a must when connecting to your business through an unsecured connection, like a Wi-Fi hotspot.

How does a VPN work?

VPN creates a secure virtual tunnel between your device to the internet, And your internet activity and web requests travel through a secure tunnel where your data is encrypted.

  • All your data and activity transmitted to the internet is redirected to the VPN rather than from the user’s computer.
  • All the data passing through the tunnel won’t be visible to hackers and they won’t be able to access your information and the activities you do online.
  • To ensure each data packet stays secure VPN wraps it in an outer pack which is then encrypted through encapsulation.
  • When the data arrives at the server, the outer packet is removed through a decryption process.
  • All your data is encrypted and routed via a VPN server, so your ISP won’t able to see your internet activity.

VPNs use advanced encryption protocols and secure tunneling techniques to encapsulate all online data transfers
