Device Security Guide

Protect phones, laptops, and tablets with updates, strong account security, cautious public Wi-Fi habits, and a VPN when you need encrypted traffic.

Includes AES-256 encryption, a kill switch, and DNS leak protection.

Why device security matters

A VPN helps on the network path, but device hygiene still decides whether malware or weak accounts can undo that protection.

Steps

  1. Keep devices updated — Install OS and app updates so known vulnerabilities are patched.
  2. Harden accounts — Use unique passwords and enable two-factor authentication on important accounts.
  3. Encrypt untrusted networks — Use AstraGuardVPN on public Wi-Fi and other untrusted networks.
  4. Review permissions — Limit app permissions and remove software you no longer use.
