The strongest encryption in the world will not help if someone walks off with your laptop unlocked. Privacy starts with the device in your hands.
We spend a lot of energy on software security and forget the obvious: a stolen or borrowed device that is already unlocked hands over everything at once.
The basics that matter
Use full-disk encryption, a strong lock screen and a short auto-lock timer. Never leave devices unattended in public. Pair those habits with a VPN and you cover both the physical and the digital sides of staying private.
