The Book

The Child Safety Protocol

A Practical Guide to Protecting Kids Online and Beyond

Coming soon

Most child safety advice is built for a world that no longer exists. This book treats family safety like an engineering problem: a clinical, blueprint-level manual for hardening your family's environment against modern exploitation, before a failure happens.

  • Layered, structural boundaries around gaming, messaging and AI platforms
  • Defense in depth for parents, not just another parental-control app
  • Written by a systems and cybersecurity engineer, not a fear merchant
