Minimize What Can Be Known

Most attacks start with reconnaissance. Adversaries map your executives, domains, vendors, job posts, exposed systems, leaked credentials, and recovery paths, then turn that into phishing, business email compromise, SIM swaps, domain impersonation, and targeted intrusion.

This guide is written for executive teams, founders, risk owners, CISOs, and IT owners who want to reduce that exposure before it becomes a crisis. It applies the OSINT Defense & Security Framework across 17 chapters: domain and email trust, identity and SIM-swap resistance, OSINT exposure reduction, executive protection, external attack surface, resilience, and incident readiness, closing with a 30/60/90 starting sequence.
