Let’s imagine a company wants to send an essential message with confidential data from site A to site B over the internet.

Without VPN, the data starts from point A through a simple router, transits over the public internet network in the clear, and reaches point B in a few seconds.

In this short journey, the information contained in the message – an industrial secret, the access data to the company account, confidential information on customers or employees – can be easily intercepted by hackers and malicious people who can use them for fraudulent purposes example,, to organize an attack—computer scientist. The potential dangers increase, of course, when connecting from hotspots or insecure WiFi networks.
