What we check before publishing a security guide
- Sources: every claim traced to a primary source (vendor docs, standards bodies, incident reports)
- Testability: steps are written so you can verify them on your own device — we avoid vendor-specific magic
- Dates: guides carry the date they were last reviewed, so you know the advice is current
- No fear-mongering: we explain risk honestly and proportionately, and never sell you a product to fix it
Frequently Asked Questions
Is the Security Hub really free?
Yes — every guide and the full Cybersecurity Fundamentals course PDF are free, no account required, no paywall, and no email signup to read them.
How current is the security advice?
Each guide shows its last-reviewed date. We refresh the core guides (router, phishing, ransomware, passwords) whenever threats or vendor defaults meaningfully change; check the article date before relying on it.
Do you recommend products for commission?
No. We do not take sponsored placements in guides, and any product mentioned is chosen for what it does, not what it pays. Affiliate links — where they exist — are always disclosed and never influence the recommendation.
