Firewall management, cloud security posture, VPN solutions, Wi-Fi protection, and container security practices.
A VPN without a kill switch leaks your real IP address every time the connection drops — even for a fraction of a second. This guide explains how kill switches work at the system level, compares application-level versus system-level implementations, and walks through enabling them on every major VPN provider and operating system.
