- Global server footprint and anti-censorship resilience.
- Strong no-logs and leak protection posture.
Quick Answer
Learn how a VPN kill switch blocks traffic during drops, how to test it safely, and why it matters for privacy.
Quick Comparison
A VPN kill switch blocks internet traffic if the encrypted tunnel disconnects, helping prevent your real IP or DNS requests from leaking during network changes.
Test it by switching servers, toggling Wi-Fi, sleeping the device, and checking whether traffic stops until the VPN reconnects.
For torrenting, public Wi-Fi, travel, and privacy-sensitive work, kill switch behavior should be tested on the exact device and app you plan to use.
Entity Layer
OpenVPN
Open-source protocol widely used for secure tunnels.
AES-256
Strong encryption standard used for VPN transport security.
DNS Leak Protection
Prevents DNS requests from exposing browsing activity outside the VPN tunnel.
Split Tunneling
Lets users choose which traffic goes through VPN and which goes direct.
ISP Throttling
Bandwidth slowdowns by internet providers based on traffic type.
Geo-blocking
Regional content restrictions often used by streaming platforms.
No-logs Policy
Provider commitment not to retain activity logs tied to users.
