Ever wished you could protect certain apps with a VPN whilst keeping others on your regular internet connection? That's precisely what split tunneling does. This powerful yet often misunderstood VPN feature gives you granular control over which applications or websites use the encrypted VPN tunnel and which don't. Let's dive into how it works and whether you should be using it.
What Is Split Tunneling?
Split tunneling is a VPN feature that allows you to divide your internet traffic between your VPN connection and your regular, unencrypted internet connection simultaneously. Think of it as having two separate lanes on a motorway – some of your data travels through the secure, encrypted VPN tunnel, whilst other data goes directly through your standard internet service provider (ISP).
Without split tunneling, when you connect to a VPN, all your internet traffic is routed through the VPN server. This provides complete protection but can sometimes slow down certain activities or cause complications with local network devices. Split tunneling offers flexibility by letting you choose which applications deserve that extra layer of security and which can function normally.
How Split Tunneling Works
When you enable split tunneling, your VPN client creates rules that determine which data packets should be encrypted and routed through the VPN server. You can typically configure this in three ways:
- App-based split tunneling: Select specific applications to either include or exclude from the VPN tunnel
- URL-based split tunneling: Choose particular websites or domains to route through or around the VPN
- IP-based split tunneling: Route traffic to specific IP addresses through the VPN whilst allowing everything else to bypass it
Benefits of Using Split Tunneling
Split tunneling isn't just a fancy feature – it solves several real-world problems that VPN users frequently encounter. Here's why you might want to use it:
Faster Connection Speeds
VPN encryption adds a layer of processing that can slow down your internet speed. By routing only sensitive traffic through the VPN, you can maintain faster speeds for activities that don't require encryption, such as online gaming or streaming from your local Netflix library. With services like NovaBridgeVPN offering 48+ global servers, you already get excellent speeds, but split tunneling can optimise performance even further.
Access Local and Foreign Content Simultaneously
Perhaps you want to access content from a different country through the VPN whilst still being able to print to your local network printer or access your smart home devices. Split tunneling makes this possible without constantly connecting and disconnecting from your VPN.
Reduced Bandwidth Usage
If you're on a metered connection or your VPN service has data caps (though quality providers like NovaBridgeVPN offer unlimited bandwidth even on their free plan), split tunneling helps conserve VPN bandwidth by only routing essential traffic through the encrypted tunnel.
Better Performance for Local Services
Certain applications and services work better with your local IP address. Online banking apps, for instance, might flag VPN connections as suspicious. Split tunneling lets you exclude these apps from the VPN whilst keeping your other activities protected.
Potential Risks and Drawbacks
Whilst split tunneling is incredibly useful, it's important to understand the potential security implications before enabling it.
Reduced Privacy Protection
The primary concern is that traffic outside the VPN tunnel remains visible to your ISP and potentially vulnerable to interception. If you accidentally exclude a privacy-sensitive application from the VPN, you're exposing that data. This is why it's crucial to carefully consider which apps and websites truly need to bypass the VPN.
IP Address Leaks
If not configured properly, split tunneling can potentially leak your real IP address through the unprotected connection. Reputable VPN providers implement safeguards against this, but it's worth testing your configuration to ensure you're not inadvertently exposing your identity.
Increased Complexity
Managing split tunneling rules requires some technical understanding. If you're new to VPNs, you might find it easier to start with a full VPN connection until you're comfortable with how everything works.
When Should You Use Split Tunneling?
Split tunneling isn't right for every situation. Here's when it makes sense to use it and when you should avoid it:
Good Use Cases
- Working from home: Protect work-related applications through the VPN whilst allowing personal browsing on your regular connection
- Gaming whilst browsing: Route your browser through a VPN for privacy whilst keeping your game traffic on the faster, direct connection for lower latency
- Streaming local content: Access geo-restricted content on certain apps whilst streaming from your local region on others
- Using smart home devices: Keep IoT devices on your local network whilst protecting your general browsing
When to Avoid Split Tunneling
If you're using public Wi-Fi or untrusted networks, it's best to route all your traffic through the VPN for maximum protection. Similarly, if you're in a country with strict internet censorship or surveillance, avoid split tunneling to ensure all your activities remain private. When in doubt, full VPN protection with AES-256 encryption is always the safer choice.
Getting Started with Split Tunneling
Most modern VPN applications make configuring split tunneling straightforward. Look for the feature in your VPN's settings menu – it might be called "split tunneling," "app settings," or "VPN bypass." Start by adding just one or two applications to test how it works before creating more complex rules.
NovaBridgeVPN includes split tunneling functionality, allowing you to customise your connection based on your specific needs whilst maintaining the robust security features you expect, including a strict no-logs policy and military-grade encryption. At just £1.99 per month, you get advanced features without the premium price tag.
