SKILLS
ABOUT ANDREW BUCHANAN
I work with cyber and information security problems that sit in the gaps — between technology, regulation, and organisational reality — where ownership is unclear, answers aren’t obvious, and judgement matters.With over 25 years of experience across software engineering, security architecture, and leadership roles in highly regulated environments, I bring a calm, structured, engineering-led approach to complex risk decisions. I’m a Chartered Engineer (CEng) with deep experience in banking, payments, cloud, and emerging technologies such as AI and machine learning.Career highlights include:Delivering secure designs for diverse initiatives, from payment systems and Microsoft Certificate Services to security embedded within AI and machine learning projects.Providing trusted security guidance across complex platforms and programmes in large financial institutions.Mentoring and developing junior consultants, fostering confidence, critical thinking, and sound professional judgement.Drawing on an early career in software development (C++, Delphi, Java) to approach security challenges through a systems and engineering lens.My work is underpinned by a strong sense of fairness, integrity, and respect for the human impact of technology decisions. I aim to deliver security that is not only technically sound and compliant, but proportionate, pragmatic, and aligned to real organisational needs.I tend to do my best work where the constraints are real, the problem isn’t neatly owned, and there’s space for honest, experience-led discussion rather than performative assurance. I’m particularly interested in how trust, ethics, and risk decisions play out when technology, people, and incentives collide.Outside of work, I enjoy building and flying drones, contributing to open-source projects, and continuously upskilling in areas such as cloud computing and quantum technologies. I’m motivated by creative problem-solving, continuous learning, and working on challenges that genuinely matter.
