My path to security leadership came through offensive security testing, software engineering, and product management. I've written code, designed and built security products, created and sold managed security services, and served as both GM and CISO for organizations ranging from early-stage startups to multi-billion-dollar enterprises. That background shapes how I approach security: I understand the trade-offs engineering teams face, I know what's actually feasible to implement and operate, and I prioritize controls that reduce real risk over ones that just satisfy auditors. I stay hands-on with cloud architecture, application security, AI, and emerging threats. At IOmergent, my co-founder Brett Wilson and I work with growing companies that need real security leadership but aren't ready for a full-time CISO. We provide fractional CISO (vCISO) services, managed cloud security, and practical assessments that tell you where you actually stand. Our focus is on building security into engineering culture and operations, as well as with executive teams. We work extensively with SaaS companies, healthcare and fintech organizations, and AI startups navigating their first enterprise customers, dealing with incidents or near misses, or trying to figure out what "good enough" security actually looks like for their stage. If you're a founder or technical leader looking to mature your security posture, preparing for your first compliance audit, or navigating an incident and need experienced support, I'm always happy to connect. And if you just want to talk through a security challenge with someone who's been there, reach out.
