Why should I use a VPN?
Virtual Private Network (VPN) extends a private network over a public network. In this way, users can exchange data through computers connected to a public network (often the Internet), as if these computer systems are connected under a private network. Applications run through VPN can thus benefit from many benefits such as simple private network management and security.
The VPN is a computer network that transmits information over a public network such as the Internet, but thanks to encryption algorithms, these connections remain private. Considering the staggering cost of setting up local area networks, VPN is a great way to connect computers.
When VPN technology was developed, it was primarily to provide users with access to remote computers' resources and applications. For example, one of the most widely used services of VPN is to connect employees to the company's computer network at work through the Internet and provide the possibility of telecommuting. This means that the employee can sit at home and connect to private networks via the Internet (public network) without having a physical connection to the work computer network.
In VPN technology, to ensure security, data is exchanged through safe routes, and users are forced to bypass authentication methods. These methods include the use of passwords, tokens, and other unique authentication methods.
A VPN is created virtually by setting up a point-to-point connection. In this way, dedicated connections such as virtual tunneling protocols (Virtual Tunneling Protocols) or traffic encryption are used. VPN available from the public Internet can provide some WAN capabilities. From an application point of view, the private network's resources connected to it will be used remotely.
The key to understanding VPN usage and finding the answer to VPN is understanding the term "Virtual Private Network." Within any organization and company where a computer is essential, setting up a computer network and connecting systems to each other is also negligible. In this regard, collections set up local area networks (LANs) or WANs at a cost. LAN and WAN is an example of the division of computer networks based on geographical area. Thus, a company that does not meet the needs of a WAN network will have to spend millions or maybe billions of dollars and provide an extensive dedicated connection for itself! VPN has eliminated the need to do so.
