3 Common Types of VPNs in 2022

3 Common Types of VPNs in 2022 


Virtual Private Networks (VPNs) have helped millions of private and public businesses secure their networks against attacks and prevent monitoring eyes on their day-to-day operations. Additionally, VPN users can access foreign websites with restricted content while enjoying a high level of privacy while transferring sensitive business information across networks.

Business owners can leverage VPNs to manage multiple accounts, block certain unwanted activities on the network, and keep data safe. VPN owners use two major VPN features you need to find out. These features are relatively advanced, but more importantly, you need to understand which one suits your business needs better.

The two major advanced VPN features are Split tunnel and Full tunnel. Both of them have their different uses, pros, and cons. 

Now, let’s dive in deeper.

What is VPN Split Tunneling?

Split tunneling is an advanced VPN security feature that allows users to split between apps and programs to have a secure VPN tunnel and enjoy increased speed and access to local services. By using VPN split tunneling, the open network and VPN service share your traffic, reducing pressure on company data centers and HQ servers. In addition, this will save costs on hardware.

What is VPN Full Tunneling?

Full tunnel implies using a VPN service for your total traffic. In essence, this method uses a single channel for transmitting and delivering traffic between a client and the organization.

Split tunnel vs. Full tunnel: The significant differences between these two VPN features are security and speed. Since the full tunnel option allows all traffic to pass through a single tunnel, it offers a good level of protection for sensitive data. This will make it hard for hackers or tracking systems to access it. However, since all traffic will be using the tunnel and require encryption, there will be pressure on company data centers and HQ infrastructure, leading to slow speed. 

On the other hand, VPN split tunneling only sends part of your traffic through a VPN tunnel while the rest goes through an open network, boosting efficiency and network performance with reduced burden on the HQ infrastructure.

Key Features of the Split Tunnel

  • Traffic is distributed between VPN Client and the Public network.
  • It prioritizes performance over security.
  • There is smoother and faster traffic flow, but not all endpoint traffic is encrypted.

Split Tunneling in NordLayer: What You Should Know

VPN split tunneling in NordLayer is activated by default. First, your traffic is routed via a Virtual Private Gateway before being split, an approach that gives you an experience of both features. In essence, you’ll enjoy top-level traffic protection and retain good performance as the NordLayer VPN servers have up to NordLayer VPN servers have up to 1Gbps output.

Is There Any Security Risk to Split Tunneling?

There may be some levels of security risks if your VPN split tunneling isn’t correctly set up. However, you should focus more on securing essential traffic to enhance speed and bolster user experience with any potential compromise on data.

Types of VPNs

Virtual Private Networks come in different shapes and purposes, and a beginner user might be unable to differentiate them. However, there are three main VPN types you must know, and they are remote-access VPNs, intranet-based site-to-site, and extranet-based site-to-site.

1. Remote Access VPN

Remote Access VPNs are used primarily for personal use and by remote workers who are probably trying to get resources for their own business on the internet and protect their online presence or are working for a company from their homes. The remote work access links a VPN user to a secure remote server for easy network access without compromising the user’s and their data’s security.

This also serves as a basis for developing commercial VPNs. With the help of such providers, a user can hide data (sent and received) from tracking systems. You are also not affected by geo-restrictions when using a remote access VPN. And more importantly, your sensitive data will not land in the wrong hands.

Suppose you are a remote access VPN user. In that case, you’ll enjoy two significant benefits: the simple setup process and the possibility of using without many technicalities, whether as a beginner user or a VPN veteran. However, large-scale business owners may not find this VPN type very suitable. While working remotely, a freelancer or remote worker can leverage applications and data stored in a corporate data center and encrypt all transmitted data between a client user and their organization.

In securing transmitted data, a VPN creates an encrypted tunnel between users and their organization’s network. So while the user may be located in an open area in public, their online activities are kept private. Their IP addresses are disguised, and their identity is converted to the selected VPN server. So, while workers in a company can work anywhere in the world, they will enjoy virtually the same privilege as someone physically located in the office environment when a remote access VPN is deployed.

2. Intranet-based Site-to-Site

Site-to-site VPNs do not work precisely like remote access VPNs. While remote access is used by workers working from diverse remote locations, Site-to-site VPNs offer different users with various fixed locations and the ability to access each other’s resources without external interference. So, suppose you are situated in the United States and working for a branch of a company headquartered in the United Kingdom. In that case, you’ll collaborate with employees in both locations and access the same resources because your local area networks (LANs) are connected to the same WAN to safely and securely share resources and data. This VPN type is well-suitable for businesses with large-scale networks.

The intranet-based site-to-site VPN connects multiple LANs to build a WAN, a setup an organization can also make to integrate Software-Defined WAN (SD-WAN). These VPN options are great for combining resources in offices located in diverse locations as if they were very close. An organization will particularly enjoy the use of an intranet-based site-to-site VPN if they house unique processes that would be of high benefit to an entire organization.

3. Extranet-based Site-to-Site

Unlike the Intranet-based site-to-site VPN used in a single company, the Extranet-based site-to-site VPNs are mainly used in more than one company. This is because they are often used to distribute mutually beneficial resources while collaborating and sharing data required for implementing specific tasks without exposing sensitive data.
