A cybersecurity leader's effectiveness is closely tied to their relationships with key business leaders such as the CIO, General Counsel, Head of Internal Audit, CFO, and CEO, as well as with the board of directors. The evolution of the role now often requires regular reporting to the board, especially in high-risk industries. Support from the board can influence senior leadership decisions on investment and priorities and establish organizational tone from the top. Key strategies for building a strong board relationship include understanding the board's oversight role, knowing each member's background, speaking their language, providing clear information on risks and actions, and using real examples to build credibility. Regularly updating and seeking feedback from the board, and engaging in activities like tabletop exercises, can deepen this critical relationship and enhance cybersecurity efforts.
