Enabling a world where the skilled application of secure digital technology reduces social harm and underpins economic prosperity.

We mitigate critical risk of social, economic or ‘threat to life’ consequences where digital technology influences the behaviour of the physical world, and vice-versa.


Helping organisations, companies and countries to help themselves by developing and scaling self-sustaining and resilient cyber capabilities.


Advising investors, shareholders and C-suite executives on the physical and digital cyber-risks to their critical data and systems.


Providing technology-agnostic cyber assurance, incident response and compliance solutions tailorable to any organisation’s size and complexity.

We are business leaders, security consultants, data analysts, technology experts, ethical hackers and compliance specialists.


Our backgrounds range from academia to ex-military, many having served with secure government departments in past careers.

Join James, our Commercial Director, on his Cyber learning journey and meet a few of the team along the way.


Our people are passionate about making a difference.  We don’t ‘turn handles’ or ’tread water’, it’s not in our DNA.  We apply equal doses of professionalism and humour to our work, which is technically and geographically diverse.  Last, but by no means least, we are parents, brothers, sisters, sons and daughters…we understand priorities and the need for flexibility and work-life balance.
