How does VPN work, what is it and why is it so important to use it? If you use the internet for work or for any other reason, you can’t help but have a VPN installed on all of your devices.
Let’s start with the meaning of the word VPN, which simply means “virtual private network”. But how does the VPN work? In a nutshell, VPN is a service that encrypts your internet traffic at 100%.
Let’s find out something more together …
What is a VPN
A VPN, therefore, is a particular network service that can be used to encrypt Internet traffic and, consequently, protect your online identity but above all our data.
In a purely business environment, a VPN can be compared to a geographical extension of the private local network (LAN) and which, therefore, allows the sites of the same company located throughout the territory to be connected to each other in a secure manner.
To do this, the routing of data packets is exploited through the IP protocol for transport on a geographic scale: this allows, in fact, to create a “virtual” and “private” LAN, but completely equivalent to a physical infrastructure of dedicated network.
What a VPN is for
The first thing you need a VPN is for sure to make your internet connection 100% secure.
Imagine a public Wi-Fi network, such as a coffee shop or airport network. Usually, you would connect without thinking twice … but how do you know who could be monitoring network traffic?
Are you sure that the hotspot is safe and not run by criminals who want to access your personal data? Think about your passwords, bank account details, credit card numbers, and any other private information you send every time you browse the internet.
If you enable a VPN, all the data you send and receive travels through an encrypted tunnel, so no one can get their hands on your private information. So even if a cybercriminal somehow managed to intercept your data, he would not be able to decrypt it.
Why use a VPN
Without a VPN, your connection is totally open. Your ISP, your employer, your favorite coffee shop’s Wi-Fi router, any server nearby, or someone with the right tools can view your data, log it, and use it in ways you have no control over.
Government agencies can monitor your online activity and share recorded metadata with each other, even across national borders thanks to cooperation agreements between intelligence agencies such as “14 Eyes”.
Based on your IP address, which depends on your geographic location, third party sites and services may show you different prices for the same item or service, or bombard you with annoying intrusive advertisements.
With a VPN, you can have peace of mind knowing that your data is encrypted and your IP address is hidden . Your ISP is no longer able to see which websites you visit, because all your activity goes through the VPN server. As a result, it cannot collect your internet metadata or keep your browsing history.
