Why privacy reached the boardroom
Several pressures arrived at once. Customers and enterprise buyers send security questionnaires before they sign. Investors ask about incidents during diligence. Every US state now has a data breach notification law, and a growing number of states have broader consumer privacy laws, so a single incident can bring duties in many places at once.
For public companies, the Securities and Exchange Commission adopted rules in 2023 that require disclosure of material cybersecurity incidents and annual disclosure about how the company manages cyber risk and how the board oversees it. Private companies are not covered by those rules, but the expectation they express, that directors know how risk is governed, has spread well beyond listed companies.
Directors of Delaware corporations will also hear their counsel discuss the duty of oversight that Delaware courts have developed over the years. What that duty requires in any particular company is a question for the board's own attorney, and this article does not try to answer it.
