Split tunneling is a clever VPN feature that lets you decide exactly which of your internet traffic gets encrypted and which travels on the regular internet. Think of it as creating a secure express lane for your sensitive apps while letting everything else cruise along in the normal lanes. This way, you get top-notch security where it counts, without bottlenecking your entire connection.
What Is Split Tunneling? A Simple Introduction
Picture your internet connection as a highway. A standard VPN shoves all your traffic—from your confidential banking app to your Netflix stream—into a single, heavily armored convoy. While that’s incredibly secure, it can create a major traffic jam, slowing everything down. Split tunneling, on the other hand, acts like a smart traffic director.
It gives you the power to route your banking and work files through the armored convoy (the VPN tunnel), while your music streaming and online gaming can zip along in the faster, standard lanes. This strikes a perfect balance:
- Targeted Security: You only encrypt the data that actually needs it.
- Maximum Speed: Enjoy faster speeds and lower lag for your day-to-day activities.
- Local Access: You can still connect to local devices, like a wireless printer, without having to disconnect the VPN first.
Despite how useful it is, this feature is still surprisingly unknown. In a recent survey of American VPN users, only 38% even knew what split tunneling was. For those who do use it, the benefits are obvious—from slashing unnecessary VPN overhead to making video calls crystal clear. You can dig into more data on VPN user habits to see how features like this get adopted.
Key Takeaway: Split tunneling gives you the best of both worlds—unbreakable security for sensitive tasks and full-throttle performance for everything else.
Split Tunneling At a Glance
To make it even clearer, let's break down how different activities are handled with and without split tunneling. This table shows you exactly what traffic goes where.
| Activity | Without Split Tunneling (Full VPN) | With Split Tunneling |
|---|---|---|
| Online Banking | Encrypted through the VPN | Encrypted through the VPN |
| Streaming Netflix | Encrypted through the VPN (might cause buffering) | Uses your regular, faster internet connection |
| Remote Work | Encrypted through the VPN | Encrypted through the VPN |
| Online Gaming | Encrypted through the VPN (higher latency/lag) | Uses your regular, low-latency internet |
| Printing Locally | Blocked unless your VPN supports LAN access | Works seamlessly over your local network |
| General Browsing | Encrypted through the VPN | Uses your regular internet connection |
As you can see, split tunneling lets you intelligently route your traffic, applying maximum security where it's needed and prioritizing speed where it's not. It’s all about making your VPN work for you, not the other way around.
How Split Tunneling Actually Works
Think of your VPN app as a smart traffic controller at a busy intersection. When you flip on split tunneling, you’re essentially giving that controller a specific set of rules for your internet traffic. It then carefully directs some of your data—say, from a specific app or website—down the secure, encrypted VPN highway while waving all other data through your normal, direct internet route.
This creates two data streams at the same time, giving you the best of both worlds: tight security where you need it and raw speed where you don't. The infographic below shows this in action, comparing a full VPN connection to a split tunnel setup.
As you can see, a full VPN shoves all your traffic through one secure channel. Split tunneling, on the other hand, intelligently separates it. This separation is usually handled in one of two ways.
App-Based Split Tunneling
The most common method you'll run into is app-based split tunneling. It's exactly what it sounds like: you pick which apps on your device get to use the VPN. For instance, you could set up your Tegant VPN to protect only your file-sharing client and work apps like Slack, leaving everything else to connect normally.
This is incredibly practical for keeping certain activities locked down without slowing down the rest of your device.
- Secure your downloads: Route just your torrent client through the VPN.
- Protect work data: Ensure traffic from your company apps always travels through the secure tunnel.
- Stream locally: Let your streaming apps use your direct internet connection for the best possible performance.
URL-Based Split Tunneling
For more fine-tuned control, there's URL-based split tunneling (sometimes called inverse split tunneling). Instead of choosing entire apps, you specify which websites or IP addresses should use the VPN. This is perfect when you only need that extra layer of encryption for a few specific online destinations.
For example, you could set your VPN to only protect traffic going to your online banking portal and your company's web dashboard. Every other site you visit, from news outlets to social media, would use your regular, faster connection.
Ultimately, both methods give you precise control over your digital footprint. You get to decide what gets the armored-truck treatment and what can travel in the fast lane, tailoring your connection to perfectly match your need for both privacy and speed.
The Real Benefits of Using Split Tunneling
So, why bother setting up split tunneling? It all comes down to a blend of practical security and seamless performance. By selectively routing your traffic, you gain a level of control that a standard, all-or-nothing VPN connection just can't match. This targeted approach unlocks four key benefits that really change your day-to-day online experience.
First off, it boosts your internet speed. Let's be honest, encrypting every single bit of data takes processing power and can create a bottleneck for your connection. With split tunneling, you can send high-bandwidth activities like streaming or gaming through your regular, faster internet connection while keeping your sensitive work data safely encrypted.
Second, it lets you access local and international services simultaneously. We’ve all been there—needing to print a document on a wireless printer while connected to an overseas work server. A full VPN would block that local network access, but split tunneling lets you do both without constantly flipping your VPN on and off.
Maximize Both Security and Efficiency
This intelligent traffic management means you maintain security where it counts without killing your workflow. You can secure your banking app and work emails while letting less critical apps, like a weather forecast or a local news site, run at full speed.
This approach exploded in popularity as remote work became the norm. The early 2020s saw VPN usage in the U.S. jump by 124% as people looked for ways to protect work data while still accessing local services and streaming content without a performance hit. You can dig into more of these trends in VPN adoption if you're curious.
Key Insight: Split tunneling prevents the common trade-off between security and speed, allowing you to have both simultaneously.
Finally, split tunneling helps you conserve bandwidth. This is a huge win for anyone using a mobile device with a limited data plan. By not forcing every app through the VPN, you cut down on unnecessary data consumption, saving money and preserving your monthly allowance for what really matters. It’s simply a smarter way to manage your digital life.
The Risks and Downsides You Need to Know
While split tunneling is a fantastic tool for balancing speed and security, it's not without its trade-offs. You have to be aware of what you're getting into. The main risk is simple: any traffic you route outside the encrypted VPN tunnel is completely unprotected.
This means your Internet Service Provider (ISP) can see those activities, and that data is exposed when you’re on sketchy networks, like the Wi-Fi at your local coffee shop. You're basically choosing to leave a specific part of your digital traffic out in the open for the sake of convenience.
The Real Danger of Data Leaks
The biggest headache comes from setting it up wrong. Let's be honest, figuring out the rules for what goes through the VPN and what doesn't can be tricky, especially if you're new to this. One wrong click could send sensitive data from an app you thought was secure over your regular, unencrypted connection.
This gets especially dicey on public Wi-Fi, a favorite hunting ground for cybercriminals looking to intercept unprotected traffic. If you want to dive deeper into securing your connection in these spots, it’s worth learning how to prevent man-in-the-middle attacks to keep your data locked down.
Crucial Reminder: The convenience of split tunneling comes with the responsibility of getting the configuration right. If you're ever in doubt, or when you're dealing with highly sensitive data, just use the full VPN connection. It’s always the safer bet.
This isn't to say you should avoid split tunneling altogether. Not at all. It just means you need to be mindful. Always double-check which apps and websites are running through the VPN tunnel and which ones are not. For things like online banking, work files, or anything with personal info, making sure they always go through the VPN is non-negotiable. For everything else, you can enjoy that extra speed with peace of mind.
When To Use Split Tunneling: Real-World Scenarios
Knowing the theory is one thing, but seeing split tunneling in action is where it really clicks. This feature is a game-changer in everyday situations where you're juggling the need for security, speed, and simple convenience. Let’s walk through a few practical, real-world examples to see how different people use a split tunneling VPN to solve some very common headaches.
Each of these mini-case studies breaks down a specific challenge and shows how split tunneling offers the perfect fix. You’ll quickly see how it can fit right into your own online life.
The Remote Worker: Juggling Security and Speed
Meet Alex. As a remote employee, Alex needs constant, secure access to the company’s internal network. A full VPN connection is mandatory for getting to sensitive files and internal dashboards. But here's the catch: that same connection makes high-bandwidth activities like video calls on Zoom or Teams painfully slow, leading to lag and frozen screens.
- The Problem: The all-or-nothing VPN tunnel is crippling essential communication tools, turning important meetings into a glitchy mess.
- The Solution: Alex fires up split tunneling to route only the company’s specific apps and websites through the VPN. This keeps all work data locked down while letting Zoom traffic zip along the faster, direct internet connection. The result? A secure link to work and flawless video calls.
The Gamer: Conquering Lag and Borders
Now let's look at Ben, a serious online gamer. He wants to jump on international game servers to play with friends overseas or get his hands on region-exclusive content. Using a full VPN would force all his device’s traffic through that distant server, which would crank up the lag on everything else—like his Discord chat and the music he's streaming.
Key Application: Split tunneling lets gamers route only their game traffic through a specific VPN server. This minimizes latency for the game itself while keeping other apps on a low-ping, local connection.
This selective routing is a game-changer, literally. Ben can connect to a server in Japan for his favorite game while chatting with friends on Discord with crystal-clear audio over his local connection. No compromises.
The Privacy-Conscious Downloader: Staying Safe and Local
Finally, there’s Chloe. She’s all about online privacy, especially when downloading files with a peer-to-peer (P2P) client. She needs to make sure her download activity is completely anonymous and invisible to her ISP. At the same time, she wants to browse local news sites and log into her online bank, which might flag a login from a strange IP address. Some ISPs even perform deep inspections on traffic; you can get the full story in our guide on what is deep packet inspection.
By using split tunneling, Chloe configures her Tegant VPN to encrypt traffic from her P2P client only. This keeps her downloads secure and anonymous while she can browse local sites and access her bank without setting off any alarms or slowing things down.
Should You Use Split Tunneling: A Quick Guide
Still not sure when to flip the switch? This table breaks down common activities to help you decide when to go full VPN and when to split your traffic.

Ultimately, split tunneling gives you the flexibility to customize your VPN use on the fly. It's about getting the protection you need, right where you need it, without sacrificing the speed and convenience you want for everything else.
How to Set Up Split Tunneling in Your VPN
Ready to take control of your internet traffic? Good news: setting up split tunneling is way simpler than it sounds. While the exact steps might look a little different from one VPN app to another, the basic idea is the same. You definitely don't need to be a network engineer to get this working.
First, you'll need to pop open your VPN app's settings. Poke around for a section labeled "Split Tunneling," "Connection Preferences," or something along those lines. Once you find it, you'll usually see two main ways to manage your apps and websites.
Choosing Your Mode
Your main decision comes down to two different approaches. Each one gives you a distinct way to control which apps get to use the VPN connection.
- Exclusive Mode (Recommended Apps): Think of this as a VIP list. This mode sends only the specific apps you select through the secure VPN tunnel. Everything else on your device just connects to the internet normally. It's the perfect setup for protecting specific activities, like torrenting files or connecting to your company's private network.
- Inclusive Mode (Excluded Apps): This one is the complete opposite. It routes all your device's traffic through the VPN by default, except for the apps you specifically tell it to ignore. This is super useful if you want total protection but need certain apps—like your local banking app or a specific streaming service—to bypass the VPN for speed or compatibility reasons.
The screenshot below gives you a good idea of what this looks like in practice. It's usually a simple list where you can add or remove apps.
This simple toggle gives you incredibly precise control over your traffic. For instance, if you want to make sure your downloads are private while your everyday web browsing stays lightning-fast, Exclusive Mode is your best friend. And to really lock down your privacy, it's also a great idea to learn how to prevent IP address tracking.
Common Questions About Split Tunneling
Even after you get the hang of it, a few questions about split tunneling tend to pop up. Let's walk through the most common ones so you can use this feature like a pro.
Is Split Tunneling Safe on Public Wi-Fi?
This is a big one. Any traffic you send outside the VPN tunnel is not encrypted. Period. That means it's a really bad idea to let sensitive apps, like your banking or email, bypass the VPN when you're on public Wi-Fi.
A good rule of thumb: If an app handles personal data, it goes through the VPN. Less critical apps can take the fast lane. But if you're in a coffee shop, airport, or hotel, your safest bet is always to use a full, all-traffic VPN connection.
Does Split Tunneling Always Make My Internet Faster?
Usually, but not every single time. Letting high-bandwidth activities like streaming or gaming bypass the VPN typically gives you better performance because it cuts down on latency. No extra stops for your data.
However, there's a catch. If your Internet Service Provider (ISP) is throttling certain kinds of traffic (like video streams), sending that traffic through the VPN might actually speed it up by hiding it from your ISP. Your mileage will vary depending on your specific network conditions.
Why Don't All VPNs Offer Split Tunneling?
Honestly? Because it's hard to do right. Building a stable and secure split tunneling feature takes serious engineering effort to prevent accidental data leaks. It’s not something you can just bolt on.
Not all providers are willing to invest the resources to build and maintain it properly. If a VPN service doesn't offer it, it can be a sign that the platform isn't as mature or feature-rich as others.
