what you’ll be able to do
Lock down your accounts

Unique passwords, two-factor, physical keys: no door left open.

Harden your phone

Permissions, encryption, backups. Your whole life is on it — treat it that way.

Spot the scams

Phishing, fake texts, social engineering: see the trap before you click.

Back up for real

The 3-2-1 rule: not even ransomware destroys anything irreplaceable.

Encrypt your messages

End-to-end messaging: what you write is between you and your recipient.

Shrink your footprint

Browser, search engine, metadata: less of you in circulation.

where it comes from

A book, put into practice

Every action and every tool comes from the book “Être en cybersécurité — votre feuille de route cyber” (Éditions Spinelle). I put it online for free so it gets used, not so it gathers dust. (The book itself is in French.)

My belief: 90% of cybersecurity problems are solved by a few good habits, not by technical expertise. The book stays the full “why”: the context, the stories, the mindset.

Where to start? With the basics.

Ten actions are enough to stop the vast majority of real attacks. The rest is refinement.
