What Is VPN Split Tunneling? Pros, Risks and Setup Checks
Quick answer
Split tunneling lets some traffic use the VPN while other traffic stays direct
VPN split tunneling is useful when you do not want every app to use the VPN. You might route your browser through the VPN while keeping banking, gaming, video calls, or local printers on your normal connection. The trade-off is that excluded apps are not protected by the VPN tunnel.
A normal VPN setup routes most device traffic through the encrypted tunnel. Split tunneling changes that. It lets you decide which apps, websites, or IP ranges should use the VPN and which should bypass it.
That flexibility is useful, but it makes privacy more complicated. If you exclude the wrong app, that app uses your normal IP address and normal network path.
When split tunneling is useful
Keep banking outside the VPN
Some banks challenge logins from VPN server IPs. Split tunneling can leave banking on your normal connection while other apps use the VPN.
Route streaming or browser traffic only
You may want one browser or streaming app protected while games, calls, or local devices stay direct.
Reduce speed overhead
Large downloads, games, or video calls can stay outside the VPN if privacy is not needed for that traffic.
Access local printers and smart devices
Some VPN setups make local-network devices awkward. Split tunneling can help if the app supports local-network exclusions.
Split tunneling risks
- Excluded apps do not get VPN IP masking or tunnel protection.
- It is easy to forget which apps are protected and which are direct.
- Browser extensions, helper apps, and background services may not follow the route you expect.
- On work or school devices, split tunneling may conflict with security policy.
App-based vs website-based split tunneling
App-based split tunneling lets you include or exclude full apps. For example, your browser could use the VPN while a game or banking app bypasses it. Website-based split tunneling is narrower: you choose domains or IP ranges that should use or avoid the VPN.
Website-based rules can be useful, but they are easier to get wrong because modern services load resources from many domains. If privacy is the priority, app-level protection with the kill switch enabled is usually easier to understand.
Setup checklist
- Decide whether your default should be “everything through VPN” or “only selected apps through VPN”.
- Keep browsers, torrent clients, travel/public-Wi-Fi apps, and privacy-sensitive tools inside the VPN unless you have a reason not to.
- Exclude only apps that genuinely need direct access, such as banking, low-latency gaming, or local-network tools.
- Test your IP address in both included and excluded browsers so you know the rules work.
- Check whether the kill switch still protects included apps if the VPN drops.
Should beginners use split tunneling?
Beginners should usually keep the VPN simple: connect the whole device, enable the kill switch, and avoid exclusions unless a specific app breaks. Split tunneling is best once you understand how the VPN route works and which apps need protection.
FAQ
Does split tunneling make a VPN faster?
It can make selected apps feel faster because they bypass the VPN. It does not make the protected VPN tunnel itself faster. For speed diagnosis, use the VPN speed loss calculator.
Is split tunneling safe on public Wi-Fi?
It depends which apps are excluded. If you exclude sensitive apps on public Wi-Fi, they lose VPN tunnel protection. For public Wi-Fi, full-device protection is usually safer.
Which VPNs include split tunneling?
Support varies by provider and operating system. Check the current app for Windows, Android, macOS, iOS, or router support before buying. Use the VPN buyer checklist to compare features before committing.
