About us


Gamma was founded by Dr. Mike Nash and Dr. David Brewer. They were two of the first consultants to advise the British Government on information security matters in the early 1980s and played a significant role in establishing the first information security laboratories in Europe and developing the UK security evaluation criteria. Indeed, Mike ran the lead UK laboratory, having already worked within NATO using the US “Orange Book”. Over the period 1987 — 1992 they worked with the British, French, Dutch and German Governments to develop the European Information Technology Security Evaluation Criteria (ITSEC) and went on to help develop ISO/IEC 15408 — the “Common Criteria”.


They joined together in 1988 to create Gamma Secure Systems Limited and embarked on providing a wide range of information security consultancy services world-wide. Over the years they have worked in over 22 countries on assignments as diverse as smart cards and information security management.

They have been particularly active in the field of international standards, where Mike has been the editor of multiple standards relating to information security.

David is now a director of IIJ Europe Limited, where he is particularly responsible for running their integrated management system, which is certified to ISO 9001 and ISO/IEC 27001.

Although now primarily retired, Mike is still active in the standards community and performs occasional consultancy assignments.
