About Bill Thorn

I empower organizations to stay ahead of cyber threats by building cutting-edge security programs that maximize value, minimize risk, and drive resilience. Security isn’t just about defense—it’s about strategy, adaptability, and relentless innovation. I champion a culture where security leaders don’t just react to threats but anticipate and outmaneuver them, ensuring every transaction is scrutinized and every risk is addressed before it becomes a crisis. I build the tools, teams, and intelligence to ensure cyber resilience across your organization with lessons acquired through experience over 20+ years leading cyber initiatives for top public and private organizations.EXPERTISE:Security Operations (SOC)* Detection & Response * Digital Transformation * Cloud Computing * Strategy * Data Protection * Incident Response * Crisis Management * Forensics * Program Planning & Implementation * Risk Management & Risk Mitigation Strategies * Threat Intelligence * Vulnerability Management * Data Analysis * Workforce Development * Team Building * Return on Investment * Cost Control * Zero Trust Architecture * Objectives and Key Results (OKRs)* Key Risk Indicators (KRIs)* Key Performance Indicators (KPIs)* Service Level Agreements (SLAs)* Security Automation * Machine Learning and Generative AI (ML/AI)* Security Engineering * Business Continuity * Budget and Financial Management * Board of Directors ReportingFRAMEWORKS & COMPLIANCE EXPERTISE:NIST CSF, NIST 800-53, NIST 800-171, CIS Critical Controls, ISO 27001/27002, PCI, HIPAA, GDPR, GLBA, SOX, CMMC
