Welcome to CyberSphere

Welcome!

CyberSphere is an independent blog about cybersecurity, written with one bias: stepping back. Rather than piling up news items or tutorials, the aim here is to understand — why an attack succeeds, what it reveals, what a new regulation actually changes, who gains and who loses when the balance of power shifts.

Decision-maker, lawyer, student, security professional or simply curious: the goal is to give you ways of reading the field, not just facts.

Editorial principles

Three principles guide every piece:

• Analyse rather than relay. An incident or a piece of legislation is only the starting point; what matters is what it says about underlying trends.
• Cite sources. Every significant claim points to a verifiable source, listed at the end of the article.
• Stay readable. No jargon for its own sake: when a technical term is needed, it is explained.

Security is a process, not a product. — Bruce Schneier

What you'll find here

Articles are organised around four main themes:

Threats & cyberattacks

Ransomware, state-aligned groups, notable incidents: how criminal ecosystems work, and what the major attacks teach us.

Geopolitics & cyberconflict

Cyberspace as a field of rivalry between states: hybrid warfare, espionage, digital sovereignty.

Regulation & compliance

NIS2, DORA, GDPR, the AI Act, the Cyber Resilience Act: what the texts say, and what they change in practice for organisations.

Strategy, economics & trends

Risk governance, the cybersecurity market, the impact of AI: security seen through the choices and trade-offs it involves.

And because it sometimes pays to get your hands dirty, a Technical section occasionally hosts more hands-on articles.

Formats for different needs

Every article carries a type: Analysis for in-depth work, Explainer to unpack a complex subject, Opinion for a stated position, Brief for a quick look, Tutorial for practice. Analyses open with a Key points box and close with their sources.

Some subjects run across several instalments — these are the series, such as "Understanding NIS2".

In French and English

CyberSphere is bilingual: your language is detected automatically, and you can switch between 🇫🇷 and 🇬🇧 at any time from the header. Translations are reviewed by a human, never published sight unseen.
