Welcome to Lines of Defence — your resource for mastering digital risk, cybersecurity, and governance in a world reshaped by technology and AI.
This platform began as a private archive of frameworks and insights for students and mentees. It’s now open to professionals like you — people who lead with clarity, resilience, and foresight in complex environments.
If you work in risk management, compliance, technology, audit, or executive leadership, you’ll find practical strategies, proven frameworks, and future-focused perspectives here — all grounded in real-world experience.
