Who Answers for Security at the Top (the CISO)

Why this matters

In a financial product, the CISO is regulator-facing, board-facing, and audit-facing. They're the single throat to choke when something goes wrong. The mature CISO: reports to CEO (not CTO/CIO), has independent board access for security incidents, owns relationships with regulators + auditors + bug-bounty programs + insurers. Without those, security is advisory; with them, it's load-bearing.

Demo

Recommendation: CISO reports to CEO with quarterly board update. CISO owns: (1) regulator interactions, (2) external audits, (3) bug bounty program, (4) cyber insurance renewal, (5) incident decisions (when to disclose). Without these explicit ownerships, the CISO is a glorified manager.

Try it yourself

1. Try to hack the CISO function: if there's a critical incident at 3am, who decides whether to (a) disclose immediately or (b) wait 24 hours for forensics? Map the actual decision flow. Without a documented path, decisions get made by panic.
2. Audit: does your CISO have board contact info? Has the board met them in the last 12 months?
3. Read one regulator filing from a fintech (e.g. NYDFS DFS-500 filing). Note who signs.
