Atholl Stewart is an Executive Principal Consultant and seasoned penetration and information security specialist with over twenty years of experience architecting and testing complex systems across finance, automotive, aviation, maritime and telecom sectors. He has led large red-team and CBEST-style assessments and delivered deep technical testing of embedded systems, payment terminals, smart TVs, cars, set-top boxes, mobile platforms and bespoke wireless solutions. His work spans ERP/CRM, MQ messaging, SaaS/PaaS, MDM and VoIP environments and includes social engineering and advanced persistent threat emulation. A CREST-qualified practitioner and long-time leader at NCC Group now at AmberWolf, he combines hands-on exploitation skills with threat modelling and program-level security architecture.
