Cyberstructure vs Extreme Privacy: Which Should You Read?
Two cybersecurity books on Privacy, compared honestly: who each is for, what each does best, and which to read first.
An engineer's lucid account of how the Internet actually works — and why its technical architecture is a political space that shapes human rights — by a DNS specialist at AFNIC.
Michael Bazzell's defender-side companion to OSINT Techniques: a step-by-step program for removing yourself from data brokers, public records, and the everyday surveillance economy without going off-grid.

Key takeaways
- Rare book that explains Internet infrastructure precisely and draws out its political consequences without hand-waving on either side.
- Bortzmeyer is a working DNS/networks engineer, so the technical descriptions are accurate, not journalistic approximations.
- Reframes privacy and freedom as design choices baked into protocols — essential context for anyone in security or policy.
- Privacy is a continuous practice, not a one-time purge: data brokers re-acquire your records every quarter, and the workflow is what holds the line.
- The hardest links to break are the ones you created yourself — utility accounts, professional licensing, vehicle titles — and most of the book is the playbook for breaking them.
- Most leaks come from people who used to know you; the book's chapters on family, devices, and shared services are the most underrated.
How they compare
We rate Extreme Privacy higher (5/5 against 4/5 for Cyberstructure). For most readers, that means Extreme Privacy is the primary pick and Cyberstructure is a useful follow-up.
Both books target intermediate-level readers, so the choice is about topic, not difficulty.
Cyberstructure and Extreme Privacy both cover Privacy, so reading them in sequence reinforces the same material from different angles.
