Who you're working with
Built inside financial-services security, not just read about it.
Sentinel is led by a practicing business information security officer who assesses AI and third-party risk for a living. The perspective is from inside the program — sitting between a business unit and a security organization, accountable for real decisions, not advising from the outside.
Work spans financial services, fintech, healthcare, and the public sector — from AppSec engineering to vendor risk to embedded security leadership. That range is why the advice is practical: it has to survive contact with how companies actually operate.
