Speakers
Penske Truck Leasing, Application Security Lead
I’m a cybersecurity professional with an M.S. in Cybersecurity and a deep interest in OSINT and recon methodologies. My work involves developing cloud-native, customer-facing applications that manage high-sensitivity PII and identity data. I lead efforts around secure authentication (OAuth2/OIDC), encrypted communications (TLS), and IAM unification across platforms. Given the attack surface of public-facing apps, recon and surface enumeration are part of my ongoing threat modeling and hardening strategy.
