Cybersecurity doesn't have to be complicated. I am here to break down concepts, threats, tips, and tools in simple language. For mere mortals and developers alike.
Since I have been asked this a lot: The best way to support this site, is to buy my books.
The Digital Fortress (Second Edition)
A warm, plain-English guide for people with real lives and finite patience. Learn the handful of habits that genuinely protect your money, accounts, and family, and get honest permission to ignore the rest.
The Anonymity Playbook (Second Edition)
A practitioner’s field manual for journalists protecting sources, whistleblowers, and activists. It explains how the surveillance actually works, what each technique costs you, and exactly where it fails.
Secure Software Development
A hands-on security guide for developers and IT professionals who ship real software. Build, deploy, and maintain secure systems without slowing down or drowning in theory.
The Secure Harness
A calm, practical guide to letting agents do useful work inside boundaries you set, enforce, and audit. Ships with 15 copy-pasteable artifacts: hook scripts, permission configs, release gates, and MCP templates.
The AI Native Engineer
Sixteen hands-on chapters, one real product. Grow it from a single model call into a retrieved, tool-using, observable, production-grade system, with evaluation treated as a habit from the first feature.
Learn how MCP can leak data or execute unwanted actions, see real-world examples (including CVEs), and apply practical defenses like container isolation, strict auth, tool allowlisting, and version pinning.
