AI governance starts with the basics

For: CISOs, CIOs, data/AI leaders and technology executives

Format: 30–40 minute talk or panel/session discussion

The temptation is to start with AI policy and new tooling before checking the basics: the business case, data ownership, identity and access.

Takeaways

  • Start with a real business case
  • Data ownership and classification
  • Human and non-human identity
  • Access boundaries
  • Human approval and stop points
  • Governance that enables adoption rather than automatically saying no

Decisions before dashboards

For: Boards, executives, CISOs and technology leaders

Format: 30 minute executive session or 45 minute workshop

Cyber reporting can produce large amounts of information without making the decision clearer.

Takeaways

  • Identify the small number of risks needing executive attention
  • Show options and trade-offs
  • Assign clear ownership
  • Distinguish operational metrics from executive decisions
  • Make risk acceptance visible
