How does VPN work?
Here is a brief of what is a VPN; let's take a look at it. A VPN offers an encrypted, secure connection between two locations. The two ends of the connection produce a common encryption key before configuring the VPN connection. A key sharing algorithm or giving the user a password can be used to do this.
All traffic passing the VPN link can be encrypted after sharing the key. As an illustration, a client computer may encrypt data before sending it to another VPN endpoint. The data will be decrypted and sent to its final destination. The entire procedure will be carried out backward when the target server sends a response.
Types of VPNs
The purpose of a VPN is to establish a secure connection between two points, but it does not specify what those points should be. This enables the usage of VPNs in a number of situations, including:
Site-to-Site VPN
A secure connection between two geographically separated locations is made possible by a site-to-site VPN. Nowadays, the majority of security gates come with VPN connectivity. A next-generation firewall (NGFW), implemented at the network's perimeter, safeguards the business network and simultaneously acts as a VPN gateway. This gateway, which encrypts the traffic supplied to the gateway at the other site, handles all traffic between the two sites. The data is decrypted and sent to its destination through this gateway.

Remote Access VPN
A secure connection between remote users and a business network is made possible by a remote access VPN. For instance, many firms switched to a remote workforce in the wake of the COVID-19 pandemic in 2020, and they set up secure remote access VPNs from distant clients to connect to crucial business processes at the corporate site.
