What Is Split Tunneling, and When Should You Enable It?

What is VPN Split Tunneling?

Let’s cover the basics first and provide the Split Tunneling definition.

Split Tunneling is a VPN feature which allows you to split your Internet traffic into two. One of them passes via an encrypted VPN tunnel, while the other one goes directly to the Internet. But here’s the thing: the part that is left unencrypted is unencrypted traffic and is potentially vulnerable to third-party monitoring and various cyber risks, so your sensitive data is no longer fully protected by your VPN.

Now, let’s look at some details to understand how Split Tunneling works, exactly.

How does Split Tunneling work?

Normally, your Internet connection flows directly from your Internet device to the server (website or platform) you wish to visit and is created by your Internet service provider (ISP). It opens up room for different third parties ranging from ad agencies to hackers and snoopers to track your activities and steal your personal information.

In turn, when you’re using a VPN, your traffic passes through a remote server, while your real IP address cannot be seen.A VPN implements a so-called encrypted tunnel governed by specific protocols such as OpenVPN, IKEv2/IPsec or WireGuard. It simply means that your sensitive information such as Google queries to messages you send are transformed into gibberish text nobody can read.

Now, what happens when you use Split Tunneling? Simply put, split tunneling lets you exclude some websites and apps from this tunnel by creating an additional route leading directly from your device to the chosen servers, giving them direct access to the Internet while other traffic destined for protected resources still goes through the VPN. As a result, most of your traffic is still encrypted and carefully protected by a VPN. 

Split Tunneling may work differently, depending on your VPN service provider, as well as device and operation system specifics. Let’s explore the most common types of this VPN feature.

Different types of Split Tunneling explained

Here are the three possible ways Split Tunneling might function.

• Inverse Split Tunneling. This is the most common type of Split Tunneling used by most VPN service providers. In fact, it functions exactly as described above – you bypass VPN encryption for only some websites and apps, while the rest of them remain encrypted.
• Application-based Split Tunneling. In this case, Split Tunneling works solely for applications. For instance, you can exclude a particular mobile game from the tunnel, while keeping a VPN running for all other apps.
• URL-based Split Tunneling. Here, the feature applies to specific websites. For instance, you can add a specific URL (like Wikipedia.com) to the list of sites you connect to without moving your data through a VPN server. 

OK, we have clarified on how Split Tunneling works, and discussed the possible ways that it could act. But, why should anyone be interested in using it, in the first place? After all, if you exclude certain traffic from the VPN tunnel, then your defense is somewhat weakened. Still, there are several significant benefits of Split Tunneling. Let’s look at them in more detail.

When do you need a Split Tunneling VPN?

Below are the primary reasons to apply Split Tunneling feature while using a VPN on your device.

To increase connection speed for specific websites or apps

It’s not a secret that a VPN makes your connection speed a bit slower due to the intensive data encryption process. In most cases this will mean nothing to you. Still, you might find it is an inconvenience when dealing with traffic-intensive activities such as online gaming, multi-part video conferencing or downloading heavy files from the Internet.

If so, it may be better to use Split Tunneling than to cancel the VPN. This way, you will get the desired apps or websites back to running normal with compromising your overall security and privacy.

To access sites and platforms that don’t support VPNs

The majority of websites and apps work perfectly with a VPN. The only difference is that they can’t detect your real IP address, as well as other details about your connection and activity. But in certain cases, you will need to exclude some applications or platforms from the VPN tunnel. 

For instance, you can’t edit a Wikipedia article while connected to a VPN. Also, you will have to turn it off when buying tickets on Ticketmaster. And that’s where Split Tunneling comes in handy. You can keep browsing securely with your VPN turned on while connecting to Wikipedia or Ticketmaster servers directly.

To get local search results

The thing about this – When you are connected to a remote VPN server, you obtain a foreign IP address. Suppose you’re on vacation in Italy, but want to get your hands on your favorite shows on American Netflix. In this case you will need to connect to the US-based VPN server. But your Google search results (as well as YouTube and some other websites) will be adapted to this virtual location, as well.So if you want to stream American Netflix but keep getting local search results, the Split Tunneling feature is your go-to.  

Another possible option is to use a VPN for just one browser while keeping another one unencrypted – you can learn how to do it here.

To access LAN devices

It sometimes happens that local devices connected to the same local network (such as your printer) don’t work properly when you’re using a VPN. That’s because your real IP becomes invisible to them, causing potential connection issues. And that’s another good reason to use Split Tunneling. Making your LAN visible to other devices on your home network will let you browse securely without losing touch with other gadgets.

In the cases above, this VPN feature can be quite convenient. But is Split Tunneling safe? Let’s consider the main issues you may face when using this VPN feature.

Split Tunneling security risks

When comparing split tunnel vs. full tunnel VPN, remember that in a full tunnel all traffic is sent through the remote user’s default gateway, while with Split Tunneling the main pitfall is that your connection is not fully encrypted. As a result, you leave a chance for your ISP, advertisers, public Wi-Fi owners, and other potential snoopers to interfere with your online activities. 

But to use Split Tunneling is still way safer than not using a VPN at all. Most of your data continues running through an encrypted tunnel and prevented from being exposed through unwanted information with additional VPN features, such as Kill Switch, IP and DNS leak protection, and more.

To make your VPN connection as reliable and secure as possible, follow these tips on using Split Tunneling safely:

• Use Split Tunneling only when necessary. Turn to this feature if you have a real need for it – as mentioned, there are a couple of situations where it’s actually helpful. Otherwise, we recommend keeping all websites and apps you’re using encrypted. 
• Avoid questionable websites and applications. Make sure to use Split Tunneling only for the websites and apps you can fully trust. Avoid applying this feature to unverified resources. Remember, the Internet is full of fishy websites, malicious links from malware, etc. Don’t share any private information on potentially insecure webpages, look hard at URLs and follow the basic online safety rules.
• Prioritize the most valuable data. While playing an online game, or scrolling through your social media feed is not that dangerous, remember to use a VPN to keep your sensitive information safe. In particular, don’t go around encryption when entering your credentials, making money transactions, downloading files from the IntenetAlso, it’s better to keep your VPN on when using public Wi-Fi in a hotel, restaurant, airport, or else – such networks are full of various cyber threats.
