If you’re interested in protecting your internet security, then you almost certainly know about VPN’s already. VPN’s or Virtual Private Networks are a crucial step in helping to keep you safe from threats on the internet in addition to keeping your data secured.

Many VPN users, however, don’t actually know how these important tools work. In this article we’re going to briefly outline how VPN’s work so you can better understand how they’re protecting you.

What Do VPNs Do?

  • VPNs allow internet users to access information through a private network. This makes it harder for people to track their data.
  • They encrypt their user’s data.
  • They work in a similar manner to a firewall, which protects the data on your computer, the main difference being that VPNs also protect your data online.

VPN’s can be used by both individuals, business, and huge corporations who are interested in keeping their most important information secure. All you have to do to do this is connect to the internet and then use some VPN software to start your VPN connection.

What Are The Different Types Of VPNs?

There are many different protocols that can be used as VPN’s.  Some of the more reliable VPN’s use a combination of these security protocols to ensure that they can provide their users with the most benefit.

Here’s an outline of a few of some of the most popular. You can also learn more about VPN’s in general by visiting here.

  • IP Security, or IPSec. This is mainly used to keep Internet communication secure. It uses either transport mode or tunneling mode, the first encrypting only the messages in a data packet and the latter encrypting the whole data packet.

  • Secure Socket Layer (SSL) and Transport Layer Security (TLS) are both used to keep the information of online stores and service providers safe. They do this by using what’s called a ‘handshake method,’ in which new encrypting protocols are developed each time a user opens a session on the website.

  • Layer 2 Tunneling Protocol is often combined with IPSec. When done this way, a very secure connection can be developed in the VPN providing both encryption and great security.

  • Point-to-Point Tunneling Protocol is the most common type of connection used for free VPNs. Unfortunately, with new modern technologies becoming available, PPTP is not regarded as safe anymore.  All it does is tunnels and encapsulates the data without actually encrypting it whatsoever.
