When it comes to virtual private networks (VPNs), organizations can use either full tunneling or split tunneling. But how do these two tunneling methods differ, and which one is applicable to your business? Split Tunneling vs Full Tunneling, are you searching for Which is Right for Your Business? Read the complete article from the beginning to the end.
This article aims to define the key characteristics of the two tunneling methods and provide tips for determining the best one for your business. By the end, you will better understand these two tunneling methods and be able to make an informed decision about which one is right for your company.
Split Tunneling vs Full Tunneling: Which is Right for Your Business
What is Split Tunneling?
A feature of VPN services called split tunneling enables customers to select which traffic should be carried over the VPN and which should be sent over the public internet. Thanks to this feature, companies can decide specifically on which information is required to be encrypted and sent through a VPN and what non-classified data is allowed to be searched on the normal internet. This, in the end, allow its users to enjoy the full range of internet content and services.

Although the question of “Why wouldn’t you want the protection of a VPN at all times?” may arise, it is important to remember that thanks to split tunneling, you can visit both local networks and the whole Internet. This might be needed for some organizations that need the help of the public internet.
Moreover, VPNs are famous for bandwidth and slow connection issues. By not directing all the traffic through the VPN, you’ll save some of the speed, and the density of connections will be much less. This would naturally result in faster connection for protected sensitive data via the use of a VPN.
What is Full Tunneling?
Full tunneling is the exact opposite of split tunneling. Regardless of the data categorization, all traffic passing over the network is under the control of the VPN and is encrypted and protected. The traffic source might be a browser, a mobile device, a mobile app, or just a computer; it does not matter, and the whole data is transmitted through a VPN.
This tunneling method is great for businesses that want all of their traffic to be protected at all times. Full tunneling is also a reasonable choice when end-users need to connect to the organization’s resources remotely.
One of the best advantages of the full tunneling feature is the increased level of security. It does indeed encrypt all the data, making it a bit more challenging for hackers to intercept. Another advantage of this tunneling model is the ability to enforce company policies on internet usage.
If all traffic is controlled by the VPN and can be monitored, the company can enforce its policies on which websites are allowed to be visited or not. With that being said, it is crucial to note that with full tunneling, the bandwidth is likely to be overwhelmed so you may experience annoying connection issues or slowness.
How to Choose the Right Tunneling Method for Your Business
Without comparing the two, we would like to emphasize that you need to prioritize your organization’s needs when choosing the right tunneling method. Depending on your needs, one of the two is not definitively better than the other.
Do your staff require access to internal resources and the ability to browse the internet generally? In that case, split tunneling with a secure VPN might be the perfect option. On the other hand, if you want to ensure that all internet communication is encrypted, full tunneling might be a better option. This is usually the case for companies that store highly-classified personal data.
Full tunneling might be the right choice if your needs prioritize security no matter what. It is technically more secure than split tunneling, but this does not mean it is without downsides. If your bandwidth is limited and you need to keep the speed high, split tunneling would help with that and offer a better connection.
Lastly, if you need to enforce strong security policies on your employees, full tunneling can help enforce those policies. However, this is sometimes not the case, and in fact, companies need to have their workers to research on the public Internet and use several websites, which would make split tunneling the best option. But regardless, as we emphasized above, it all boils down to your business needs. We provided the use cases for both methods, so it is up to you to choose the right one.
Two methods for sending internet traffic through a VPN connection are split tunneling and complete tunneling. While complete tunneling sends all internet traffic through the VPN, split tunneling allows users to pick and choose which apps and websites will use the VPN connection.
Businesses should consider their unique requirements, the necessary level of security, and internet usage restrictions before choosing between the two. Speaking with an IT professional or VPN provider may also be beneficial. Businesses may select the optimal tunneling technique for their purposes by carefully weighing their alternatives.
