About Geoff Hancock Ciso
I help mid-market CEOs and CISOs stop guessing about cybersecurity and AI risk.Not with more tools.With an operating system that produces clear decisions, measurable control, and proof you can defend to the board, to customers.Here’s what it usually looks like before I show up.AI is happening anyway (shadow use, unclear boundaries, data leakage risk) Security teams are busy, not effective (noise, tool sprawl, slow decisions)Leadership asks for confidence and gets… opinionsExceptions happen informally, accountability is fuzzy, and risk “moves” without being ownedWhat I do I operationalize cyber + AI risk so leaders can move fast without lying to themselves. That typically includes:Decision rights + accountabilityWho owns what, what requires approval, how exceptions work, and who carries consequences.Execution rhythmCadence, metrics, escalations, decision logs, and a battle rhythm that survives reality.Security fundamentals that stay runningNot “implemented once” operated, measured, and improved.AI governance that shipsEnforceable guardrails, access boundaries, validation, monitoring, and lifecycle controls—without turning governance into bureaucracy.Why listen to meI’m not coming at this as a pure advisor. I’ve built and run the machinery. 7x CISO / 2x CEO with 20+ years leading cyber and transformationBuilt and led 37 SOCs and 4 MSSPsSupported enterprise, government, and national security missions. Contributor to CIS Critical Security Controls and NIST CSF. Served on national task forces with DHS and ODNI.11+ years co-author/instructor in a Cyber MBA program. Retired U.S. Army Green Beret calm under pressure, disciplined execution, mission-first leadershipWhat I believe (that some people get wrong)Security isn’t a tool stack. It’s a decision system.Execution beats decks. If it doesn’t survive Monday morning, it doesn’t matter.AI governance should accelerate delivery. If it can’t be enforced, it’s theater.Ways to work with mevCISO / Advisory Retainer (monthly) decision support, accountability, board-ready proof. Security + AI Operating Model Build (30/60/90-day sprint) decision rights, cadence, metrics, execution engineAI Governance + Safe Enablement Program ship AI safely with enforceable boundaries and measurable assuranceIf you’re thinking: “we’re guessing,” “AI is happening anyway,” or “we’re busy but I can’t prove we’re in control,” I have been theire before and I can help.
