Different Types of VPNs and Their Functions

A VPN is an Internet connection, and there are many different types. These include client-to-server and site-to-site and many more. This article will present the different types of VPNs and their salient functions.


Site-to-Site VPN

A site-to-site VPN creates a secure tunnel between two networks. It encrypts the data traveling between the networks and adds a VPN header on top of the original IP packet. Then, it sends the encrypted package back to the other network. In addition to securing your network, site-to-site VPNs are cost-efficient, too. Third-party providers host your VPN connection, providing your remote workers with a stable, secure, and low-latency experience. These providers also offer a predictable subscription-based pricing model and are transparent about the hardware that supports their VPN solution.


Client-to-Server VPN

A client-to-server VPN is a secure connection between a client device and a corporate network. It encrypts data before reaching the provider, preventing unauthorized access or compromise. A client-to-server VPN can be extremely useful when connecting to your corporate network on unsecured public wireless networks or even if you’re traveling. This VPN connects you to a corporate network from any location and is particularly helpful for remote workers. The client connects to the server via the Internet, and the server connects to the corporate network or LAN. A client-to-server VPN can connect from a home computer to a corporate network. 


Remote Access VPN

A remote access VPN is a software application that creates a secure tunnel between an offsite employee’s device and the company network. The tunnel is created by encrypting the data and using a variety of security protocols to ensure that only authorized connections are made. A remote access VPN can be useful for a variety of business situations.

A remote access VPN is an invaluable tool for businesses with offsite employees who need to keep their data secure. Its benefits include reducing internal data breaches, facilitating a remote workforce, and defending against malicious attacks. 


Intranet-Based VPN

Intranet-based VPNs are used to connect various offices within a company. This type of VPN connects the LANs within each office to a common wide-area network (WAN). These networks allow users in different locations to access the resources and data of the company’s network.

A company can set up an intranet-based VPN by creating a tunnel connecting the Internet to the intranet. This is usually done by activating two connection objects in the connections folder. 


Extranet-Based VPN

Extranet-based VPNs can be used in a variety of situations. For instance, a VPN can be used to protect sensitive business data. In addition, an extranet VPN allows access to private network servers that are not accessible to the public Internet. These VPNs use MultiProtocol Label Switching (MPLS) to provide secure communication.


Mobile VPN

A mobile VPN is a useful tool to secure your mobile device from hackers and other threats. For example, it can prevent interruptions from buffering screens and help keep your data safe while you are connected to a public Wi-Fi hotspot. A mobile VPN can also help you avoid man-in-the-middle attacks, which are used to spy on you and your private data.

A good mobile VPN has a no-logs policy, bulletproof encryption, and unlimited bandwidth. It should also be able to unblock websites and apps and allow you to stream them safely.
