What Is a VPN? | Virtual Private Networks


How a VPN, Virtual Private Networks hides your IP address, data, and identity on the internetVPN

The acronym VPN stands for virtual private network. A VPN is a method used to connect to the internet privately. It does this by hiding your real IP address and routing your internet traffic and data through a private and securely encrypted tunnel over public networks. VPNs are popular because they provide a way to browse the internet without giving away your personal identity, location, or data. When data is encrypted inside the VPN tunnel, ISPs, search engines, marketers, hackers, and others can’t see or track your activities on the web.

How Does a VPN Network Work to Protect You?

VPNs protect you in three main ways:

  • Disguise your real IP address and location: After connecting to a VPN service, you’re sent to the internet from a new gateway server. This spoofs your IP address and makes it appear as if you’re in a different city or country than the one you’re actually in.
  • Encapsulate your internet traffic through a private VPN tunnel: Data on the internet moves in packets. With a VPN; Virtual Private Networks, all your data packets are encapsulated inside additional data packets. This encapsulation creates a private tunnel inside public networks.
  • Scramble your private data with encryption: When using a VPN service, your internet traffic and personal information inside the tunnel are scrambled using encryption. This makes a VPN connection virtually impossible to hack by outside forces.

Some of the most secure types of VPN encryption include:

  • OpenVPN
  • L2TP/IPSec (Layer 2 Tunneling Protocol)
  • IKEv2/IPSec (Internet Key Exchange version 2)
  • SSTP (Secure Socket Tunneling Protocol)
  • SSL (Secure Sockets Layer)

When Should You Use a VPN Network?

Use a VPN when browsing over public networks, at home, at the office, when traveling or living in a country with geo-restrictions, or on mobile devices. Anytime you want to browse privately (or spoof your IP address), use a VPN.

Home networks are generally private with tightly controlled access. However, everything you do online — from your Google searches to the websites you visit and the things you buy — can be linked to your IP address.

This includes browsing the internet on your mobile phone while using the company network.

This allows you to access your favorite websites, TV shows, and free communication services wherever you happen to be.
