About the Book

ServiceNow runs the operational core of thousands of regulated enterprises — yet platform security remains one of the least-documented disciplines in modern cybersecurity. This book closes that gap.

Written for CISOs, security architects, and platform owners, Securing ServiceNow is a practitioner's field guide to hardening the platform, managing API exposure, and meeting EU regulatory obligations under NIS2, DORA, the Cyber Resilience Act, and the EU AI Act.

Drawing on ten years inside ServiceNow's Office of the CISO, the book moves past generic best practices to the real attack paths, configuration gaps, and audit failures that matter. Each chapter delivers decisions, not theory: what to harden, what to monitor, what to evidence.

By the end, you will know what your exposure actually looks like, what regulators will ask, and what a real security program for ServiceNow looks like.

If your organization depends on ServiceNow — and EU regulators are watching — this is the field guide your security program needs.
