VPN was originally used to secure communication between institutions. It has become a popular application preferred by end users as results such as tracking on the Internet, privacy violations and similar results emerge. In the early days of the Internet, VPN aimed to secure the communication between institutions in different locations.
Let’s explain with an example:
Imagine that you have created a chain of stores with several branches, these branches need to communicate with the central branch and you want to contact your branches over the internet for sensitive data such as accounting records. Unfortunately, you are not safe while receiving and sending this data. You can encounter cyber attackers at every point, from the modem you connect to the internet to the service provider and even to other companies that provide the communication in between. If you connect your branches to your company’s headquarters via VPN applications and transmit the incoming and outgoing data in an encrypted manner. You provide both security and privacy. Intermediate companies or an attacker who can intervene will only see the encrypted data that is unreadable.
Security and privacy on the Internet: VPNs provide the security and privacy of the data flow on the Internet. You can safely transmit your sensitive data to the other party without interrupting your communication.
Internal communication: Institutions communicate with other institutions or with other branches and headquarters of companies using VPN protocol. In this way, the security of corporate data is ensured.
