If you are a web designer and do not use a VPN, it is time to change that.

VPNs are essential for anyone doing something online, let alone for anyone who relies on the internet for their work, and especially for those who use public networks to do so. People on norskeanmeldelser.no claim that a VPN has been very helpful.

What is a VPN?

A VPN is a service that creates an encrypted connection from your device to a VPN server through your Internet connection. Think of it as a tunnel through a mountain, where your internet service provider (ISP) is the mountain, the tunnel is the VPN connection, and the exit is to the worldwide web.

Ivacy VPN

Some people may confuse VPNs as alternatives to an Internet connection, but this is incorrect. Initially, VPNs were created to connect business networks for more secure and convenient communications. Today, VPN service providers are working to get all your traffic to the Internet – bypassing government or ISP monitoring and even forced censorship in some cases.

In short, think of a VPN as a service designed to help you gain full Internet access and protect yourself while doing so, for example, Ivacy VPN.

What does VPN do?

The main purpose of a VPN is to create a secure tunnel for your data to flow to its servers before it goes over the Internet. However, this has led to other benefits, such as spying on the location.

While this may seem insignificant to you, there are many times when spying on your location has helped people overcome location barriers. Take the Great Firewall of China for example. The Chinese government heavily censors the Internet and many things we take for granted online are blocked in China. Only by using a VPN can China-based users access sites like Google and Facebook.

For peer-to-peer (P2P) users, in addition to the identification risk, there is also the risk that your port maps will be identified by Torrenting. VPNs help you mask all of this so that open ports cannot be easily exploited.

The advantages of using a VPN connection

  • anonymity
  • Security
  • Access blocked services by geolocation (Netflix, Hulu, etc.)

As I mentioned, the first and main purpose of today’s VPNs is anonymity. By creating a secure tunnel from your device to their servers and encrypting the data traveling through that tunnel, VPNs effectively protect all your data activity.

How VPN works

It’s a little difficult to describe how a VPN works unless it’s a small technical detail. However, for those who just want the basic concept, a VPN creates a secure tunnel from your device to the VPN server and then from there to the Internet.

In detail, VPN first establishes a communication protocol on the device. This protocol will set the limits for how data will travel from your device to the VPN server. Several main VPN protocols are common, although each has its advantages and disadvantages.

How many types can a VPN be?

I can tell you that there are several types of VPNs. The one used by companies because they have a lot of internal resources (servers and data) that they need to distribute between locations (that’s why they need secure connections between networks). Now, let’s see briefly what are the most common types of VPNs on the market:

  1. Site-to-Site VPN – this type of VPN is represented in figure 1 above and offers the benefit of connectivity between Networks over other networks (such as the Internet), and at the same time provides security for traffic sent between networks
  2. Remote Access VPN – this type of VPN is most often used because it protects your Internet connection by securing it (encryption, data integrity, and authentication of the two parts) and anonymizes you on the Internet (ie hides your IP)
