Security operations, modernized — by someone who has run them.

I'm John Green — a cybersecurity leader with 20+ years running security for large public-sector organizations, now available for independent advisory and SOW work. CISSP. Former CISO. I've built and led a Security Operations Center for a multi-billion-dollar state agency protecting tens of millions of records.

I help State, Local, Tribal, and Territorial (SLTT) teams — and the firms that serve them — modernize the SOC, cut tool sprawl, and get real answers out of their security data.

• Google SecOps / Chronicle — drove an enterprise SIEM deployment and consolidated multi-cloud telemetry (GCP, AWS, Azure, on-prem).
• Compliance that actually holds — IRS 1075 / FTI, CJIS, NIST 800-53, Zero Trust architecture.
• AI at incident scale — hands-on with 286B-token / $3.7M incident telemetry; I know where AI helps SecOps and where it doesn't.

→ Engage me for advisory, SOC modernization, or SOW work.
