How did we get here?
Our Story: A Veteran Owned Business
In 2011, after 23 years in the military, former helicopter pilot, Stuart Mckean set up Nine23, a leading UK cyber security company in his home office. Having experienced the problem many employees face in using better IT equipment to do their jobs effectively and securely, Stuart felt he could bring new insights to bear on the challenges of cyber security.
Stuart founded Nine23 with a commitment to more effectively enable end-users, in compliance and regulatory industries, who were often reliant on out-dated IT solutions.
Leading Nine23’s focused and skilful team alongside Stuart, former US Army acquisition officer, Ed Jesson, Nine23’s Chairman. Ed brings a depth of experience to Nine23, having founded and run multiple technology businesses for the last three decades. He continues to deliver insights to the team to ensure a balanced and stable future.

Social Values
Nine23 are committed to social values through supporting charities and organisations.
Nine23 are part of a pilot group of technology companies working with Net Zero to create a consensus across the Tech industry as to what Net Zero means for businesses in the sector and to provide an industry standard against which business claiming to be Net Zero can be assessed.
The goal is to create a pragmatic, effective and publicly available guide for Tech firms to achieve Net Zero. This “protocol” will be practical and easy to use, whilst remaining comprehensive in its scope and ambitious in its scientific robustness – offering businesses a realistic method of achieving credible sustainability goals, in line with the global climate goals required by the Paris Agreement.
Nine23 are proud to be working in partnership with a number of global hi-tech companies and as part of the Trust X Alliance Global Goals Initiative, to address relevant areas of the UN Sustainable Development Goals.
Out of the 17 goals, 4 have been chosen with the intent that we can affect these areas the most. They are: Good Health and Well-Being (3), Gender Equality (5), Decent Work and Economic Growth (8), and Climate Action (13). Individually, Nine23 have our own targets, and are continually formulating improvements to our plan, to guarantee these goals are met.
The benefits that can be driven through social value can be a vital component in advancing equality, creating training and better employment opportunities.
At Nine23 we love to give back by supporting local and national charities and communities. Our history of support includes:
