by Christophe Mazzola · cybersecurity expert
01 — what you’ll be able to do

Take back control, one action at a time.

  1. 01

    Lock down your accounts

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

  2. 02

    Harden your phone

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

  3. 03

    Spot the scams

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

  4. 04

    Back up for real

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

  5. 05

    Encrypt your messages

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

  6. 06

    Shrink your footprint

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

02 — what it covers

16 domains, from the most fundamental to the most advanced

03 — two ways through it

Choose your pace.

04 — in the press

Read, seen, recommended.

05 — 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.

94% of attacks come through email. 60% of people reuse the same password.

06 — and also

A manual built to be used.

Not paranoia, facts: one in two French people had their data leak in a single 2024 attack. And when the news gets involved — like Chat Control returning to the European Parliament — you’ll already know what to do. The Chat Control briefing →

07 / TAKE ACTION

Where to start? With the basics.

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