Daniel Ramos · CTO, Intelligent Automation

Building, running and proving a security program in the year the attackers stopped breaking in and started logging in. Twenty-one chapters, fourteen scenario playbooks a stranger can execute at 3 a.m., and 489 tiered controls mapped to NIST CSF 2.0, CIS v8.1 and ISO 27001. Every claim cited to a primary source — and where sources disagree, it says so instead of picking a favourite.

Twenty-one chapters

Every one written to be opened on its own, by someone who has not read the rest.

Fourteen scenario playbooks

Written so somebody who has never read the book can pick one up mid-incident and run it. Ransomware, business email compromise, account takeover, identity provider compromise, supply chain, insider, data breach, DDoS, deepfake fraud, Kubernetes, AI systems, edge devices, web applications and OT.

Every claim is cited to a primary source. Where sources disagree, it says so rather than picking a favourite — and where something could not be confirmed, it is marked as unconfirmed instead of being quietly rounded off.
