“The CISO’s role is a business leadership role.”
I’ve spent more than two decades building and leading security programs at companies that operate at the highest stakes — CISO and security leadership roles across public and private companies, from the largest technology platforms in the world to growth-stage startups building enterprise products.
My career spans consumer technology, enterprise software, data analytics, financial services, and telecommunications — as both an operator scaling security inside established companies and a founding security leader inside earlier-stage ones.
Outside of executive roles, I co-host Defense in Depth, one of the most candid conversations in cybersecurity, and invest in the next generation of security tooling. Today I advise the boards, CEOs, founders, and investors navigating the questions that don’t have easy answers.
Defense in Depth
Each week, alongside David Spark, I take one debated topic in cybersecurity and pull it apart with the help of the InfoSec community — the kind of honest, unpolished conversation you’d hear at a CISO dinner.
