Choose the right perspective
Match the person's company stage and product area to yours, since leading technology at a large security vendor differs from building a platform at a younger company or running a managed detection service. Also consider whether you need a view on architecture and AI strategy or on engineering execution and scaling teams.
Questions to take into the conversation
- 01How do you decide which AI capabilities to build into a security product, and how do you validate that they hold up against real attackers?
- 02How do you balance platform consolidation against best-of-breed point products on your roadmap?
- 03How do you structure engineering and threat research so findings reach the product quickly?
