VPN split tunneling is a feature that allows the user to decide which internet traffic goes through your VPN and which goes directly through your regular internet connection. This means you can split your online activities, which apps or, better still, websites require the enhanced security and privacy of a VPN and which can go directly onto the Internet. 

For example, you might consider routing your banking app’s connection via the VPN for security purposes or streaming apps to bypass the VPN, maintain faster speeds, and access content based on your preferred region.

This feature is useful when you want a VPN connection without losing speed or local service availability. It allows you to pass only the necessary traffic through the VPN, helping conserve bandwidth and improving performance. 

However, it is important to know the process of VPN split tunneling to use it efficiently, as it is quite an important feature contributing to your online security and browsing efficiency.

By the end of this guide, you’ll know exactly what VPN split tunneling is, how it works, its benefits, and how you can use it safely to maximize your internet experience.

How Does VPN Split Tunneling Works?

Flowchart explaining how VPN split tunneling works, with traffic routed through VPN and regular IP addresses.

VPN split tunneling allows users to select which internet connections go through the VPN tunnel and which do not require VPN protection. Normally, when one logs into a VPN, his/her web traffic is routed to the VPN server through an encrypted path. 

This protects your data and hides your IP address. However, with split tunneling, you can only make specific traffic through this secure VPN tunnel.

For example, if, in your work setup, you find that you have to open some company resources securely while the rest of their internet connection is quite fine as it is, you could allow only the specific traffic to go through the VPN. 

At the same time, you’ll be able to complete all other operations, such as scrolling through social networks or streaming domestic platforms, on your ordinary connection with higher speed and less latency.

What are the Benefits of VPN Split Tunneling?

VPN split tunneling has benefits that make the feature useful to many users. Here’s a look at some key benefits:

1. Improved Internet Speed and Performance

When all your traffic goes through a VPN, the connection speed may be reduced because of the encryption. This means that you can allow high bandwidth activities like streaming, gaming, and downloading through the normal network, not through the VPN, hence improving the activities while at the same time protecting your important information.

2. Reduced Bandwidth Usage

By routing only necessary traffic through the VPN, you reduce bandwidth consumption. This can be particularly handy using a limited data connection or a mobile device. For example, you can secure your work-related traffic with the VPN, while everyday browsing or local content doesn’t affect your data limit.

3. Access Local and Foreign Content Simultaneously

The split tunneling feature allows users to access local services and content while protecting other VPN traffic. For instance, you can watch local streaming services or access Websites that may block VPN connections while your work or financial data is secured under the VPN.

4. Greater Control Over Online Security

With split tunneling, you can decide exactly what needs to be protected. This feature is especially valuable for companies and remote workers who require secure access to company resources without compromising internet performance for other purposes.

5. Flexibility for Different Use Cases

Split tunneling allows VPN users to control their VPN tunnel settings according to their specific needs. This feature can be turned on and off to prevent certain applications or traffic from passing through, accessing local content, or improving VPN internet speed, making it an ideal VPN option.

VPN split tunneling can enhance your online experience by balancing security, performance, and accessibility, making it a valuable tool for anyone who uses a VPN regularly.

What Are the Security Risks associated with VPN Split Tunneling?

Earlier we have discussed about VPN Split tunneling benefits, it’s important to know the security risks associated with this feature. Here are some potential risks you should consider:

Security risks associated with VPN split tunneling, including data leaks and reduced privacy.

1. Exposure of Unencrypted Traffic

An important concern associated with split tunneling is that the traffic that goes through the VPN tunnel is only a part of the total traffic. The rest of the traffic is not tunneled and, therefore, is not encrypted. 

This unprotected traffic can be problematic and is prone to cyber threats like hacking, spying, or interception of the transmitted data by undesired persons. For instance, if you are connecting through public WI-FI, any activity without a VPN connection can easily be intercepted.

2. Increased Risk of Data Leaks

Split tunneling can sometimes lead to data leaks if not configured properly. Sensitive information intended to be protected by the VPN could accidentally be exposed if the wrong apps or websites are excluded from the VPN tunnel. This misconfiguration can defeat the purpose of using a VPN for security and privacy.

3. Potential Vulnerability to Geo-Blocking and Censorship

Using split tunneling can make it easier for websites and services to detect your real IP address and location, especially if you’re accessing geo-restricted content. However, this could result in being blocked by websites or services that enforce strict regional restrictions or censorship, limiting your access to content.

4. Compromised Device Security

Sometimes, when some of the traffic does not go through the VPN connection, the device will likely be vulnerable to malware or phishing. Applications and services in other zones of the Internet can be attacked by cybercriminals, thus threatening the security of your device or data.

5. Reduced Overall Privacy

Split tunneling reduces the level of privacy you would typically get with a full VPN connection. Since not all traffic is hidden from your ISP or other prying eyes, your overall privacy can be diminished. This is especially concerning if you’re in a region with high surveillance or restrictive internet practices.

These are the security concerns that must be considered, as well as the measures that should be taken to decrease or prevent them. It is always important that all sensitive traffic go through the VPN and that the VPN be very selective about which application or service should not be encrypted by it.

How to Use VPN Split Tunneling?

VPN split tunneling allows users to selectively route internet traffic through a secure VPN connection or through a regular connection, ensuring network security and fast access to local services. Here’s a Step-by-Step Guide on how to use VPN split tunneling and make the most out of this feature:
