Lines of Defence is a learning space for people who want to think more clearly about digital risk, governance, and organisational resilience in a world shaped by technology and artificial intelligence.
This site exists to help you build judgement and skills, not just accumulate knowledge.
It treats cyber security, data, operations, regulation, supply chains, and AI as a single, interconnected system rather than as separate professional silos.
SubscribeWhat This Site Is For

The content is written for people who work in, around, or alongside the Lines of Defence and who want to become more effective at the boundary between technology and leadership.
