Être en cybersécurité
your cyber roadmap
The simple guide to protecting your digital life. Learn at last to defend yourself against scams, hacks and data theft through simple reflexes, no technical jargon, even if you know nothing about computers. (The book is in French.)
Everything the book asks you to do is already here, free.
The book’s 224 actions, its 83 tools and its glossary are freely available on this site: no account, no email address, no tracker. You can apply the whole book without ever buying it, that is deliberate.
Because the site gives you the actions, and the book gives you the rest: the context, the stories, the real cases, and the way of thinking that means you no longer need a checklist.
“A guide accessible to all, to better understand what’s at stake online.”
, BFM TV
“This book will teach you to defend yourself better.”
, ZATAZ
This site puts the book into action: every checklist action and every recommended tool is drawn from it. The book is the full “why”, with the context, the stories and the shift in mindset.
A book built for everyday life, not for experts
For individuals who want to stop falling for scams, freelancers and business owners who want to protect their work without becoming experts, and parents who want to guide their families online.
Every chapter ends with concrete actions: what to check, what to change, what to do when in doubt. You apply as you read, no hardware or technical prerequisites.
You won’t just memorise “rules”: you’ll understand how attackers think and why we fall for their traps. As a result, you make better decisions, naturally.
Technical notions are translated into everyday analogies, in a simple, human tone. If you can use a smartphone, you can understand and apply this book.
