Head of Information Security

The Head of Information Security owns the whole security program and is the most senior security voice in the organization - often the de facto CISO before that title formally exists. They report to a CTO, CIO, or CEO and are accountable for the outcomes, not the keystrokes: a defensible risk posture, passed audits and certifications, incidents that stay small and well-handled, and enterprise deals that don't stall in a customer's security review. The day is a negotiation between three clocks that never align: the threat clock (a critical vulnerability dropped, an alert is escalating), the deal clock (Sales needs a security questionnaire and audit report to close), and the audit clock (the certification window is closing with evidence gaps). Most of the work is deciding which clock wins today and defending that trade-off to leaders who want velocity and a board that wants zero risk. What separates great from average is risk translation and leverage: turning "we have hundreds of unpatched criticals" into a business decision leaders can weigh, accepting the risks that should be accepted in writing rather than chasing every finding to zero, and building a program where teams own security in their own systems instead of a central team being the bottleneck.
