Mike StJohn-Green


Mike is an independent consultant in cyber security, currently working with a range of clients, primarily in the City of London and Europe. Among recent assignments, he has led information security audits with three of the UK's FTSE-350 companies and offered advice to City auditors and boards, demystifying this thing called cyberspace and its security. He retired in 2013 after more than 39 years working for the UK government, mainly at GCHQ and most recently in the Office of Cyber Security and Information Assurance in the Cabinet Office. His Cabinet Office responsibilities included international relations and the role of standards in improving cyber security. He had a range of roles in GCHQ, including deputy director CESG, the Information Assurance arm of GCHQ.

Mike also works with the Information Security Forum, which publishes the internationally-recognised Standard of Good Practice. He works with the International Atomic Energy Agency chairing a standards committee. He was on the steering board of the recently published cyber security standard, PAS-555, and supports the IET's work on Cyber Security, principally by chairing committees and conferences. He is a frequent speaker and writer on the topic of cyber security. He remains, at heart, an engineer and is convinced we could build more secure systems, by design and cost-effectively avoid many of today’s security-related problems.
