The different types of VPNs:

• A remote access VPN allows a user to connect to a private network and gain remote access to all of its services and resources. The user's connection to the private network is established over the Internet, and the connection is secure and secret. Remote Access VPN is beneficial to both home and business users.
• A Site-to-Site VPN, also known as a Router-to-Router VPN, is widely employed in large corporations. Site-to-site VPN connects the network of one office location to the network of another office location for companies or organisations having branch offices in different places.
• Intranet based VPN: Intranet based VPN is when numerous offices of the same firm are connected using Site-to-Site VPN.
• Extranet based VPN: This form of VPN is used when a firm uses a Site-to-Site VPN to connect to another company's office.
