David Lynas Consulting (DLC) are global leaders in delivering business-driven cybersecurity value.

As a most trusted strategic partner, we enable our clients to meet their most important business goals through our application of architectural approaches to solve complex challenges in Cybersecurity, Information Risk, Resilience, Governance, Assurance and Trusted Engineering.

David Lynas Consulting (DLC)’s methods apply cross-industry and empower our clients not just to articulate an entirely new level of strategic ambition but deliver on that vision, balancing risk with opportunity to achieve positive benefit.

Our passion for, and commitment to, our clients’ success is characterised by a unique customer experience, and our ability to make a real difference is evidenced by two principal factors that set us apart: our people and our method.

David co-wrote the book, literally.

Our Founder

In 1995 David Lynas, and his associates John Sherwood and Andy Clark, devised a unique methodology to address cybersecurity issues for organisations. They saw a better, more positive way to look at security – holistically embedded in innovation. They called it SABSA (Sherwood Applied Business Security Architecture). David, John and Andy authored the ‘blue book’ Enterprise Security Architecture: A Business-Driven Approach in 2005 and the field of Enterprise Security Architecture was born.

With 30 years experience in security, David has been at the forefront of the Enterprise Security Architecture field since its inception in 1995, founding DLC in 2012. David is a co-author of the SABSA Methodology & Chief Education Officer at The SABSA Institute.
