What are the types of VPN?

There are three basic types of VPNs, and these include:
Site-to-Site VPN
A site-to-site VPN, also referred to as router-to-router VPN, enables offices in multiple locations to safely connect with each other.
Remote Access VPN
A remote access VPN allows a user to securely connect to a business or home network and access its resources from a remote location.
Client-Based VPN
A client-based VPN establishes a private connection between a user and remote server usually through the use of an application.
