Virtual Private Network (VPN) is a communication technology that allows you to connect to a public network and use it to join a local network, using the Internet, WAN, or SD-WAN. An example of implementing SD-WAN products is when you manage a company that consists of several branch offices. Then the company’s expenses will be greater. Especially if you use wireless or fiber optic, even though it could be between offices in different cities or even islands. With SD-WAN, we can build a link between offices by utilizing an existing internet network.
VPN is a private connection through a public network or the internet, virtual network means the network that occurs is only private where not everyone can access it. The data sent is encrypted so that it remains confidential even though it is through the public network.
VPN can send data between two computers that pass through a public network so as if it is connected point to point. The data is encapsulated with headers that contain routing information to get a point to point connection so that the data can pass through the public network and can reach the destination end.
VPN technology has a working system that encrypts all data that passes through it. With this encryption technology, your confidentiality will be better protected. Even if there are parties who can intercept your data passing by, but not necessarily they can read it easily because it is already scrambled. By implementing this encryption system, no one else can easily access and read the contents of your data network.
When passing through the Internet, your data travels very far across many countries. In the middle of its journey, anything can happen to its contents. Whether it’s lost, damaged, or even manipulated by the contents of fun people. VPN has technology that can keep the data you send to its destination without being disabled, lost, damaged, or manipulated by others.
VPN technology can authenticate the sources it sends data to. The VPN will check all incoming data and retrieve the data source information. Then the data source address will be approved if the authentication process is successful. As such, VPN guarantees all data sent and received by you from the proper source. No data is falsified or transmitted by other parties.
