Duncan Hart is a software and systems security technologist. He studied at Royal Holloway, University of London — home of the internationally renowned Information Security Group — where he completed an MSc in Information Security before carrying that postgraduate grounding through a career spent tackling complex, intractable security problems where traditional approaches consistently fail.
Duncan has worked in network and computer security since 1998, across organisations including the Bank of England, Vodafone Group, BHP, the Council of the European Union, and the National Crime Agency, UK. Spanning central banking, telecoms, resources, government, and law enforcement, his work has consistently sat at the point where security, scale, and real-world messiness collide — less about off-the-shelf fixes than the awkward problems that don't have them.
From 2008 to 2011 he served on ICANN's Security and Stability Advisory Committee (SSAC), the body advising the internet's governing organisation on the integrity of its core naming and addressing systems. On the close of his tenure, the ICANN Board acknowledged its deep appreciation for his service and wished him well in his future endeavours.
Originally from the UK, he's now based in Melbourne, Australia, where he [leads security architecture at (Company) / consults independently on large-scale systems security]. He writes about large-scale software-defined systems — [exploring the security implications of infrastructure-as-code, platform engineering, and the trade-offs teams make when they build for scale] — at [blog/publication].
