It’s hard to believe we haven’t had Mark Weatherford on an S4 stage in the last 20 years. We will correct that with Mark being our legend interview at S4x26.

Mark’s career spans an impressive array of public roles including:

  • VP & CSO at National American Electric Reliability Corporation (NERC)
  • CISO for the state of Colorado
  • CISO for the state of California
  • The first Deputy Undersecretary for Cybersecurity at DHS

He has served on numerous public and private boards, and Mark has won too numerous to mention awards. In 2025 he joined NVIDIA as the Head of Cybersecurity Policy and Strategy. This legend is not yet done.

In these legend interviews we cover key items in the career and what we can learn from them. We certainly will discuss AI and the future given Mark’s current role.
