About Jan D'Herdt

Jan D’Herdt is a SANS Certified Instructor and cybersecurity executive with deep expertise in enterprise security architecture, governance, and risk management. He teaches LDR512: Security Leadership Essentials for Managers and SEC566: Implementing and Auditing CIS Controls, equipping both security leaders and practitioners with the frameworks needed to align cybersecurity programs with business objectives and measurable risk reduction. He currently works as an independent Enterprise Security Architect and Consultant, helping organizations implement and transform the CISO organization, and align cybersecurity with governance and business risk.

Jan’s career spans more than 20 years across consulting, audit, architecture, and executive leadership roles. He previously served as Chief Information Security Officer (CISO) and Global Lead of Cybersecurity at a global biotech, where he led the global security program and aligned cybersecurity with business strategy. Before that, he was Head of Enterprise Security Architecture at a global biopharma organization, following roles at Euroclear, Johnson & Johnson, IBM, and Deloitte. Earlier in his career, he worked across IT security consulting and governance, building a foundation in audits, penetration testing, and compliance.

Jan’s teaching philosophy is grounded in realism and connection. He believes students should recognize their own challenges in the material and leave with solutions they can apply immediately. He places strong emphasis on communication, helping students explain security risks to non-technical stakeholders and drive change within their organizations. Outside of cybersecurity, Jan enjoys basketball and traveling. As a father of two, he jokes that he is a “daily risk assessor” at home, a mindset that reflects his practical and relatable approach to both leadership and teaching.
