Layered mobile security
VPN Privacy Guide
A VPN is one valuable layer in mobile privacy. It protects a defined network path, while carrier security, device hardening, account authentication, app permissions, and encrypted communications address other risks.
01
Protect the network path
Choose a transparent VPN, enable reliable auto-connect or always-on behavior, verify DNS and IPv6, and test cellular, Wi-Fi, SIM switching, and hotspots.
02
Protect the carrier account
Use a unique password, account PIN, number lock, secure email, and a response plan for unexplained loss of service. A VPN does not stop SIM swapping.
03
Protect the device and apps
Keep software current, use a strong passcode, review location and contact permissions, remove abandoned profiles, and install apps only from verified sources.
04
Protect accounts and recovery
Prefer passkeys, authenticator apps, or hardware security keys for valuable services. Keep backup codes offline and avoid temporary travel numbers as sole recovery methods.
