Sam Stepanyan is an application security architect and consultant with nine years in senior roles and over two decades of hands-on software and infrastructure experience. Based in London, he combines enterprise security practice—contracting at Schroders, Deutsche Bank and Lloyds—with leadership of the OWASP London chapter since 2015 and a seat on the OWASP Global Board. He founded Step9 Consulting to deliver application security, WAF and delivery-layer solutions for finance and large-scale web platforms, reflecting deep expertise in secure architectures and pragmatic controls. Sam’s background ranges from early web and intranet development to managing security teams and integrating complex products like F5 and Imperva, giving him rare full-stack visibility into risk across development and operations. He is known for translating regulatory and business needs into auditable security programmes and for growing community-driven security practices through OWASP. An early career in telecommunications and public-sector programming underpins his practical, systems-level approach to application security.
