Two-Factor Authentication
The two-factor method most people use, a text message code, is also the weakest, thanks to SIM-swapping.
VPNs
A VPN shields your traffic in transit, but the VPN company itself can still see it, so trust matters as much as marketing.
Password Security
The single biggest security upgrade most people could make costs nothing and takes ten minutes: stop reusing passwords.
Phishing
The "you've won a prize" email is old news — today's version knows your boss's name and writes in perfect corporate tone.
Data Breaches
Most of the damage from a data breach doesn't happen the day it's discovered — it happens months later, when the stolen data finally gets used.
Encryption
The little padlock icon in your browser's address bar represents encryption quietly scrambling your data on essentially every website you visit.
Ransomware
Ransomware doesn't have to steal a thing: it just locks you out of your own files and charges you for the key.
