About
Harnessing public-private partnerships to achieve greater mission impact.
What is Industry 100?
Industry 100 (i100) is the principal initiative from the NCSC to facilitate close collaboration with the best and most diverse minds in UK industry.
As the national technical authority on cyber security, our ambition is to make the UK the safest place to live and do business online. But we can’t do this alone. Every citizen, business and government department has a part to play.
i100 brings together public and private sector talent to challenge thinking, test innovative ideas and enable greater understanding of cyber security – one of the most important issues of our time.
In i100, we are bringing industry and government expertise together to help us all learn lessons, identify systemic vulnerabilities and reduce the impact of cyber attacks.
How does Industry 100 work at the NCSC?
i100 secondees work across a wide range of placements on a part time basis, ranging from one day a week to one day a month.
Participating organisations continue to pay the salary of their staff member while on secondment with us, to maintain independence.
To apply, please get in touch via our Industry 100 Expression of Interest Form and supplement this with a copy of your CV to [email protected], and we can work with you to explore potential i100 placements (Please see Joining i100 for details). If a suitable match is found, we will arrange an informal chat with you and the prospective NCSC team to discuss placement opportunities, and you will have a chance to ask questions. If a placement is agreed, arrangements to onboard you to i100 will get started.
Please note:
All i100 secondees will require a Security Check clearance.
For more information on SC clearance, please see the Joining i100 section.
i100 Annual Update - October 2025
As noted in the NCSC Annual Review 2025, the Industry 100 (i100) scheme has continued to strengthen the NCSC’s mission with specialist skills, diverse perspectives and real world insights from private sector experts. An additional 43 new participants joined this year, seeing the community grow to an all time high of 160 strong.
Over 80% of i100 secondees were rated as ‘valuable’, ‘highly valuable’, or ‘indispensable’ to delivering mission outcomes by their NCSC hosts. Impact was highest within the national resilience mission, with the energy sector overtaking finance as the aspect of critical national infrastructure most heavily represented on i100.
We have also expanded i100 expertise around emerging technologies including post quantum cryptography, artificial intelligence, and biometric authentication. Specific highlights from i100 this year included:
- technical research into cyber security risks to the aviation sector including in relation to satellite navigation systems
- pivotal contributions to the development of the NCSC’s Share and Defend capability, particularly in relation to threat intelligence data and indicator sharing
- international engagement with over 15 countries - from Ukraine to the Republic of Korea – delivering workshops about the UK’s world leading approach to public private partnership
