Split tunneling is a VPN setting that divides your internet traffic into two paths. Some data goes through the encrypted VPN tunnel, whilst other data bypasses the VPN entirely and connects directly to your internet service provider.
This differs from a standard VPN connection, where all traffic flows through the VPN server. With split tunneling, you choose which apps, websites, or IP ranges use the VPN and which do not.
Why use it?
- Speed: VPNs add slight latency. Sending local or non-sensitive traffic directly can improve gaming or video call performance.
- Local access: Printers, NAS drives, and home automation devices often require a direct connection to your network.
- Streaming: Some services block or throttle VPN traffic; split tunneling lets you watch them without the VPN.
- Bandwidth: Keeping heavy downloads off the VPN reduces server load.
Real example: You could route your banking app through the VPN for security, whilst letting Netflix use your direct connection to avoid buffering.
What to look for: Not all VPN providers offer split tunneling. Check the app settings or provider documentation. Some allow you to exclude individual apps, others let you exclude entire websites or IP addresses. Ensure your VPN app supports your operating system (macOS, Windows, iOS, Android) before buying.
Split tunneling trades security convenience for flexibility. Traffic that bypasses the VPN is not encrypted, so reserve it for activities where privacy is less critical.
