// About Rex
Security content
that doesn’t
assume you’re technical.
Most cybersecurity content falls into one of two traps: it’s either written for IT professionals, or it’s designed to scare you into buying something.
Rex Calloway exists to do neither.
This site is for people who use the internet the way most people use the internet — on a phone, a laptop, and a handful of apps — and who want to understand what’s actually happening to their data, without needing a computer science degree to follow along.
// The approach
- Plain English, not jargon. When technical terms come up, they get explained.
- Specific steps, not vague advice. You’ll know exactly what to change and where to find it.
- No fear-mongering. The goal is to reduce your actual risk, not your sense of comfort with technology.
- Free basics, deeper paid content. The foundational guides are free. Paid resources go further.
What this site covers
Passwords & Accounts
Password managers, two-factor authentication, what to do after a breach, and how account takeovers actually happen.

Lock screen settings, app permissions, the privacy options buried three menus deep, and what your phone is actually sharing.
Browsing & Email
Trackers, browser fingerprinting, phishing anatomy, and the handful of extensions that actually matter.
Networks & VPNs
Public Wi-Fi risks, what VPNs actually do (and don’t do), DNS settings, and how to think about network trust.
Social Media Privacy
What the platforms actually collect, which settings to change, whether deleting helps, and what data brokers do with it.
Scams & Social Engineering
How phishing, SIM swapping, and fake tech support work — and how to recognize them before they work on you.
Why 20+ years?
Cybersecurity hygiene and online privacy have been a focus for over two decades — long before “data privacy” was a mainstream concern. That perspective matters: the advice here isn’t driven by whatever threat is trending this week, but by a long view of what actually protects people over time.
The fundamentals haven’t changed. Strong, unique passwords. Two-factor authentication. Skepticism of unsolicited contact. Understanding what you’re giving away when you use a free service. This site covers the fundamentals clearly, then goes deeper for those who want it.
“You don’t need to be a security professional to protect yourself online. You just need to know what actually matters.”
