About Us


The CyberFish Team


We are an eclectic team of social scientists, engineers and cyber security experts applying our hard-won knowledge to see good people, who want to build society and jobs having an easier time, and criminals having a harder one.


Our Team

Unique in the crisis management exercising market, our team brings a powerful combination of skills, including technology risk management, decision-making and cyber security.


Many advisors are good at either the technical side of incident response, or the behavioural side of leadership and decision-making. 

Through the Resilience Dojo Exercising and Learning Platform, we do both, together, with expert knowledge from both sides. Our exercises have helped hundreds of cyber security leaders working in mission-critical teams across the globe, to improve the effectiveness of their crisis management teams, leading to improved decision-making and stakeholder communications.

Berta founded CyberFish in 2018 with the goal of helping cyber incident teams improve their effectiveness during crises. She brings her expertise in organisational psychology and her experience in managing global cyber threat intel teams to achieve this mission.


Berta holds two Masters degrees, one in Social Sciences from the University of Linköping and another in Neuroscience and Psychology from King’s College’s IOPPN. Her research interests focus on the relationship between crisis management team cohesion and cyber resilience.


As CEO, Berta has successfully managed CyberFish UK and Malta, establishing strategic partnerships, engaging with clients, and completing accelerator programmes. In 2024, she transitioned to the CyberFish Board to further contribute to the development of cyber resilience in the UK. She continues to provide support to the CyberFish leadership team and the Board in scaling the business and delivering client engagements when needed.


Berta also serves as an Independent Non-Executive Director on the Board of Trust Stamp, and a member of the Advisory Board of the Research Institute for Sociotechnical Cyber Security (RISCS) in the UK.

John joined the team in 2020 as Technical Director, and manages the engineering team. He has spent many years developing technical capability, and managing engineering teams, within secure government, a small technology business, and the cyber division of a large defence prime. 

He values quality and reliability in products, allowing users and support staff to feel confident in their capabilities. His most valuable achievements have been building up teams and watching them achieve solutions to really hard problems, in a way that doesn't sacrifice quality.


As well as leading the CyberFish engineering team, John advises Judicial Commissioners in the UK on the possibilities and risks of police and security agency teams using the latest technology for investigations. 

Nik joined the CyberFish leadership team as Chief Sales Officer in 2024. Nik looks back on 20 years of extensive experience and track record in driving sales growth and building innovation from the ground up within various business sectors.

Our company values drive everything we do, from recruiting our team members, to managing our people, developing our solutions, taking on new Clients, working together in partnership with them, and supporting our local communities.


The most important of these values are:

We are committed to honesty, fairness, and respect, amongst ourselves, with customers and prospects, partners, and even competitors. We are honest about what we can deliver to customers. By offering a scalable learning platform, we make our offering available also for small businesses, schools and local government customers in developing countries.

We embrace diversity in who we are, and how we think. We take great care not to discriminate on the basis of (or make unsupported assumptions about) gender, ethnicity, religion, or any other protected minority group attribute.

We love learning new things and we keep an open mind for different views: doing so helps us innovate. At the same time we make sure our solutions are based on pragmatic solutions and scientific evidence.

Advisory Board

Our Advisory Board members are trusted industry experts in areas we rely on to keep our business successful, and learning programmes current and evidence-based.
