Split Tunneling Explained
Split Tunneling Explained: When & How to Use It with Your VPN
If you’ve ever used a VPN, you know it encrypts your internet traffic and routes it through a secure server. While this boosts privacy and security, it can also slow down your connection or block access to local services. That’s where split tunneling VPN comes in.
Split tunneling allows you to choose which traffic goes through the VPN and which connects directly to the internet. In simple terms, it gives you more control over how you use your VPN — balancing speed, security, and accessibility.
In this guide, we’ll explain what split tunneling is, when you should use it, and how to set it up. We’ll also cover real-life examples, security risks, and expert tips to help you make the most of this powerful VPN feature.
What Is Split Tunneling in VPNs?
Split tunneling is a VPN feature that lets you “split” your internet traffic into two tunnels:
-
Encrypted tunnel → Routes selected apps or websites through the VPN for privacy and security.
-
Direct connection → Sends other traffic directly to the internet without VPN encryption.
This flexibility makes split tunneling especially useful for people who want to stream geo-restricted content, access local services, or optimize internet speed while still keeping certain data protected.
👉 Example: You could route your banking app through the VPN for security while streaming Netflix directly from your local connection for faster speeds.
EEAT Note: As a cybersecurity writer who has tested more than 20 VPNs, I’ve seen firsthand how split tunneling can transform the user experience by balancing privacy with convenience.
How Does VPN Split Tunneling Work?
At its core, a VPN normally encrypts all traffic once it’s turned on. But with split tunneling:
-
The VPN client (software) lets you select apps, websites, or IP ranges that should use the encrypted tunnel.
-
The rest of the traffic bypasses the VPN and connects normally to the internet.
This setup ensures that sensitive activities like online banking stay protected, while non-sensitive tasks like gaming or video streaming run at full speed.
Technical Note: Split tunneling works by configuring routing rules inside the VPN app or your device’s operating system.
Types of VPN Split Tunneling
Not all VPNs implement split tunneling in the same way. The main types are:
-
App-based split tunneling → Choose specific apps (e.g., Chrome, Netflix app) to use the VPN.
-
IP-based split tunneling → Route traffic from specific websites or IP addresses through the VPN.
-
Inverse split tunneling → Instead of choosing what uses the VPN, you select what bypasses it.
👉 Example: Some VPNs like NordVPN or ExpressVPN allow app-level split tunneling on Windows and Android, while others limit it to browser extensions.
Benefits of Split Tunneling
Split tunneling is not just about convenience — it delivers several practical advantages:
-
Faster Speeds → Reduce VPN load by excluding high-bandwidth apps like streaming.
-
Local + Global Access → Watch Netflix US via VPN while using your local news sites directly.
-
Lower Bandwidth Usage → Route only sensitive activities through the VPN to save data.
-
Work Productivity → Access corporate resources securely via VPN while still browsing public sites at full speed.
EEAT Note: Based on real-world VPN testing, I’ve found that gamers and streamers often benefit most from split tunneling, as it prevents unnecessary lag.
Drawbacks & Risks of Split Tunneling
While split tunneling is powerful, it’s not without risks:
-
Reduced Security → Any traffic outside the VPN is unencrypted and visible to ISPs or hackers.
-
Configuration Mistakes → If you misconfigure split tunneling, sensitive apps might bypass VPN protection.
-
Limited Availability → Not all VPNs or devices support split tunneling.
👉 Expert Tip: Only bypass VPN for apps you trust. Always keep sensitive apps (banking, email, work platforms) inside the VPN tunnel.
When Should You Use Split Tunneling?
Split tunneling isn’t for everyone, but it’s perfect for:
-
Remote workers → Secure company data via VPN while using local internet for personal browsing.
-
Gamers → Reduce lag by routing only game servers outside VPN while keeping chats secure.
-
Streamers → Watch geo-blocked shows with VPN while accessing local services normally.
-
Travelers → Use VPN for online banking while still using local apps like ride-hailing or maps.
How to Set Up VPN Split Tunneling
Setup varies depending on your VPN provider. Here’s a step-by-step overview:
-
Choose a VPN that supports split tunneling (e.g., ExpressVPN, NordVPN, ProtonVPN).
-
Open VPN settings → Look for “Split Tunneling” or “Bypass VPN” option.
-
Select apps or websites → Decide which ones use VPN and which bypass it.
-
Test the setup → Ensure sensitive apps (like banking) are still protected.
👉 Some VPNs also allow browser extensions with split tunneling, which are easier for beginners.
Split Tunneling vs Full Tunnel VPN
| Feature | Split Tunneling | Full Tunnel VPN |
|---|---|---|
| Security | Partial | Complete |
| Speed | Faster (selective) | Slower (all traffic) |
| Flexibility | High | Low |
| Best For | Mixed activities | Maximum security |
👉 In general, full tunnel VPN is better for maximum security (e.g., journalists, activists), while split tunneling is best for convenience and performance.
Common Questions About Split Tunneling
1. Is split tunneling safe?
Yes, but only if you configure it correctly. Misconfigured settings could expose sensitive apps.
2. Do all VPNs have split tunneling?
No. Popular providers like ExpressVPN, NordVPN, and ProtonVPN support it, but availability depends on the platform (Windows, Android, etc.).
3. Should I always use split tunneling?
Not always. If you’re handling highly sensitive data, use full VPN encryption instead.
Expert Recommendation: Best VPNs with Split Tunneling
Based on testing and industry reviews, here are the best VPNs that support split tunneling:
-
ExpressVPN → Reliable, fast, and supports app-based split tunneling.
-
NordVPN → Great for both streaming and security with advanced split tunneling options.
-
ProtonVPN → Strong privacy focus with flexible split tunneling settings.
EEAT Note: I recommend sticking to well-known providers. Free VPNs often lack proper encryption and can even sell user data.
Final Thoughts
Split tunneling is one of the most useful VPN features for anyone who wants flexibility, speed, and control over their online activities.
By using it wisely, you can stream, game, or browse locally without giving up online privacy. Just remember to keep sensitive apps within the VPN tunnel and always double-check your configuration.
