CISO Role Shifts To Data Strategist
- AI shifts the CISO role from building walls to becoming a business strategist responsible for operationalizing data.
- CISOs must supplement legacy controls with data visibility to enable AI initiatives safely.
Legacy Data Lakes Are High Value And High Risk
- Legacy data lakes hold the most value for AI, but also the greatest risk if left unclassified.
- Organizations must discover, contextualize, and profile historic data before serving it to AI.
Automate Classification With An AI Mesh
- Use specialized small models (an AI mesh) to interrogate and classify large repositories automatically.
- Tag and profile discovered documents so you can make informed, policy-driven decisions.
