Why I built Sentinel
I started Saberistic — a strategic cybersecurity consulting firm — because I kept seeing the same problem at the high end of the market. Enterprises had IT departments, MSSPs, compliance frameworks. Families with equivalent complexity — physician couples, hedge fund partners, second-generation wealth — had nothing. Their exposure was real, their appetite for risk was low, and the options available to them were either consumer tools designed for someone else or enterprise contracts priced for someone else.
Before that, I was a CTO building products at the intersection of design and technology, and before that, an engineer in blockchain infrastructure — an environment where custody mistakes are permanent and threat modeling is a survival skill, not an optional exercise.
Sentinel is the service I kept wishing existed. A named operator, not a help desk. Personal accountability, not a ticket queue. Built for people whose digital posture is genuinely complex and who can't afford to treat it as an afterthought.
