There are roughly 35,000 CISOs worldwide serving an estimated 359 million businesses. That 10,000-to-1 ratio is not a hiring problem. It’s what the 2026 CISO Report from Cybersecurity Ventures and Sophos calls a market failure.

Most companies under $50 million in revenue never close that gap with a full-time hire; the math doesn’t work at that scale. Instead, security decisions get made informally: an IT director carrying a second job, a compliance program built to pass audits rather than manage risk, or no one at all. Host David Shaw (CISSP, GLEG) walks through what actually fills the gap: a full-time CISO, an internal promotion, or a fractional vCISO, what each one costs, where each one works, and where each one fails.

In this episode:

  • The 10,000-to-1 CISO-to-business ratio, and why the 2026 CISO Report calls it a market failure
  • The three informal models that fill the gap when there’s no security leader, and why each one breaks down under pressure
  • Full-time CISO vs. internal promotion vs. fractional vCISO: honest costs and tradeoffs for each
  • The revenue thresholds where each option actually makes sense
  • An illustrative example of what an unaddressed gap costs when a known, escalated risk goes unfixed

The Security Leadership Readiness Check, five questions:

  1. Who is accountable to the CEO or board for security risk, by name, as a primary responsibility?
  2. When was security last on the board agenda as a standalone item, not folded into an IT update?
  3. Do you have a documented security roadmap with budget attached, reviewed at least annually?
  4. In the last 12 months, has an executive overridden an IT security recommendation, and do you know why?
  5. If you had a material security incident tomorrow, who makes the notification and response decisions, and have you rehearsed it?
