Day_01 // Monday, August 3

All day & night.

Afternoon · Nomination-only

NextGen CISO Forum

  • WhiteRabbit is bringing together the next generation of security executives — not sitting CISOs, but the people sitting CISOs believe are ready to make the jump.
  • The Road to the Chair — Caleb Sima + Chaim Mazal (CISO, GitLab). The real version of how you actually get there, not the LinkedIn version.
  • First 90 Days — Nicole Grinstead (Roblox) + Jake Schroeder (LVT)
  • On the Hook — David Hirsch (former Head of SEC Cyber/Crypto Enforcement)
  • The State of the Search — Michael Piacente (Hitch Partners) + Tom Alcock (Code Red Partners)
