TL;DR
Split tunneling is a VPN feature that lets users route specific apps or websites outside the encrypted tunnel, offering better control over privacy, security, and performance. Its support varies across providers, but it remains underused.
Split tunneling is emerging as a key feature in VPN services, offering users the ability to route specific apps or websites outside the encrypted tunnel. This feature enhances both security and performance, especially for high-bandwidth or location-sensitive activities. While not all VPN providers support it, its adoption is increasing, making it a significant development for users seeking greater control over their online privacy and network efficiency.
Split tunneling allows users to select which applications or websites bypass the VPN’s encryption, leaving the rest of the device’s traffic protected. This can be implemented as a whitelist (apps that use the VPN) or a blocklist (apps that bypass it). Major providers like Surfshark, IPVanish, and ExpressVPN support split tunneling, though support varies across platforms and operating systems. For example, some providers offer router-level configuration, while support on iOS and macOS remains limited due to system restrictions.
Support for split tunneling is inconsistent; some VPNs like ProtonVPN support it broadly, while others like NordVPN face challenges on certain devices. Its primary use cases include accessing local devices without VPN interference, improving bandwidth for streaming or gaming, and maintaining access to geo-restricted services. However, enabling split tunneling can expose some traffic to potential tracking or leaks, especially if DNS leaks are not properly managed.
Why Split Tunneling Matters for VPN Users
Split tunneling offers a balance between security and usability, allowing users to enjoy fast internet speeds and access local devices while maintaining privacy on sensitive activities like banking or work-related tasks. Its increasing support signifies a shift towards more flexible VPN solutions that cater to diverse user needs. However, inconsistent implementation and potential security risks mean users must understand when and how to use it effectively.

Evolution and Adoption of Split Tunneling in VPNs
Initially, VPNs routed all traffic through encrypted tunnels, prioritizing privacy but often at the cost of speed and compatibility with certain apps. As VPN technology matured, split tunneling emerged as a feature to optimize performance and usability. Major providers have introduced support over recent years, with some offering platform-specific solutions. The feature remains underutilized, partly due to inconsistent support and security considerations, but its popularity is growing as users seek more control over their network traffic.
“Split tunneling is a relatively new VPN feature that lets you route specific apps or websites through your VPN, while the rest of your device’s network uses your unencrypted network.”

Support Variability and Security Risks of Split Tunneling
Support for split tunneling remains inconsistent across VPN providers and platforms, especially on iOS and macOS where system restrictions limit implementation. Additionally, enabling split tunneling can expose certain traffic to leaks or tracking if DNS leaks are not properly managed. It is not yet clear how widespread or secure these implementations are across all providers and devices, and ongoing updates may change support levels.

Future Trends and Improvements in Split Tunneling Support
VPN providers are likely to expand support for split tunneling, especially at the router level, to improve compatibility and security. Expect more platform-specific solutions and clearer guidelines on secure usage. As awareness grows, more users will leverage split tunneling to optimize their VPN experience, but security concerns will continue to influence how providers implement and promote this feature. Monitoring updates from major VPN services will reveal how the feature evolves.
