Network security: six guides to harden your connection
Public WiFi, kill switch, MAC spoofing, WPA2 vs WPA3, Tor vs VPN, mobile hotspot: six analyses to understand real attack vectors and pick the right countermeasures.
Beyond the VPN: network security
A VPN protects your outbound traffic but does nothing against a compromised WiFi access point, an open Bluetooth or an Evil Twin hotspot. Network security is every layer above and below the VPN tunnel.
These six guides detail real threats (not marketing scenarios), explain countermeasures that actually work (kill switch, WPA3, MAC spoofing) and compare complementary tools like Tor or mobile tethering.
Practical angle: tested on recent hardware (2024-2026), with limits documented, indicating when VPN alone is enough - and when you must stack another layer.
