Why read cybersecurity books in French when the canon is in English?

Three reasons: access (a good book in your own language removes a barrier), angle (French legal, strategic and academic writing has its own perspective), and pedagogy (textbooks like Ghernaouti or Avoine et al. are excellent course material). For the most advanced offensive tradecraft, English remains unavoidable — but for foundations, academia, law and strategy, French has real gems.

Which French cybersecurity book should I start with?

It depends on your goal. La cybersécurité (Arpagian) is a one-afternoon orientation; Cybersécurité (Ghernaouti) is the structured academic survey; and Sécurité informatique – Ethical Hacking (ACISSI) is where to go if you want hands-on offensive practice right away.

Do these books replace the English references?

No, they complement them. The technical canon — pentesting, reverse engineering, malware analysis — is still overwhelmingly English. The French books shine on foundations, the academic and legal angle, and on cyber strategy and geopolitics.

Which French book covers cyber strategy and geopolitics?

Cyberstratégie by Bertrand Boyer for the doctrine and statecraft, and Cyberstructure by Stéphane Bortzmeyer to understand how the technical architecture of the Internet becomes a political and human-rights issue.

The 8 Best French-Language Cybersecurity Books (2026)

Almost all serious cybersecurity literature is in English — but there is a core of French-language books that genuinely hold up, several with an angle (legal, strategic, academic) you won't find elsewhere. Here are the eight worth your time, in a reading order that runs from public-facing orientation to technical manual. Useful if you read French, or want the French/European perspective the English canon tends to skip.

The picks at a glance

La cybersécurité — Nicolas Arpagian (PUF, “Que sais-je ?”) — the fastest orientation to the stakes.
Cybersécurité — Solange Ghernaouti (Dunod) — the reference academic survey.
Sécurité informatique — Principes et méthodes — Bloch & Wolfhugel (Eyrolles) — the why of security architecture.
Sécurité informatique — Cours et exercices corrigés — Avoine, Junod, Oechslin & Pasini (Vuibert) — the cryptographic foundations.
Sécurité informatique — Ethical Hacking — ACISSI collective (ENI) — the big offensive manual.
Hacking et Forensic — Ebel & Hennecart (ENI) — build your own tools in Python.
Cyberstructure — Stéphane Bortzmeyer (C&F éditions) — the Internet as a political space.
Cyberstratégie — Bertrand Boyer (Nuvis) — cyber as a domain of warfare.

To understand the stakes

La cybersécurité by Nicolas Arpagian, in the “Que sais-je ?” series, is the ideal starting point for a non-specialist: 128 pages laying out threats, actors and public-policy stakes in an afternoon. It's an orientation, not training — but it's exactly the book to hand a leader or colleague who needs the essentials fast.

Cybersécurité by Solange Ghernaouti (Dunod, 7th edition) is the reference French academic textbook. Its strength is structure rather than technical depth: risk analysis, governance, legal and organisational dimensions. It's the backbone of many French degree programs — read it for framing, pair it with a hands-on book.

The technical foundations

Sécurité informatique — Principes et méthodes by Bloch & Wolfhugel (Eyrolles) is one of the few French books written from the defender-architect's chair: it explains the why of security architecture instead of cataloguing tools. Ideal for admins, architects and RSSI.

Sécurité informatique — Cours et exercices corrigés by Avoine, Junod, Oechslin & Pasini (Vuibert) is the strongest French-language treatment of the cryptographic and formal foundations — written by real cryptographers (Oechslin invented rainbow tables). With corrected exercises, it's a course companion, not beach reading.

Offensive practice

Sécurité informatique — Ethical Hacking by the ACISSI collective (ENI) is the big French offensive manual: reconnaissance, network and web attacks, social engineering, forensics, Metasploit — all lab-driven. It's the closest French equivalent to the English pentest canon; treat it as a workbook with a lab VM open.

Hacking et Forensic by Franck Ebel & Jérôme Hennecart (ENI) picks up for the reader who wants to build tools rather than buy them: sockets, packet manipulation, web and forensic scripting in Python. The French answer to the “Black Hat Python” tradition.

Infrastructure and strategy

Cyberstructure by Stéphane Bortzmeyer (C&F éditions, winner of the FIC Cyber Book Prize 2019) explains exactly how the Internet works — DNS, routing, protocols — and why that technical architecture is a political space shaping privacy and freedom. A rare book that takes both the engineering and the politics seriously.

Cyberstratégie by Bertrand Boyer (Nuvis) treats cyberspace as a theatre of operations: doctrine, deterrence, statecraft. It brings a French/European strategic lens to a conversation usually dominated by American voices.

Where to start

If you're a beginner or coming from management, start with La cybersécurité (Arpagian), then Cybersécurité (Ghernaouti) for the survey. If you're technical and aiming offensive, jump to Ethical Hacking (ACISSI), then Hacking et Forensic to build tooling. For the political and strategic dimension — too often neglected — Cyberstructure and Cyberstratégie are the two to read.

And to be honest: none of these replaces the English canon for the most advanced technical tradecraft. But for foundations, academia, law and strategy, French has real gems.
