Cyber Flywheel Boosts UK Cybersecurity Startups

The UK government and business leaders are being encouraged to support the growth of a stronger cybersecurity startup ecosystem through a new initiative known as the “cyber flywheel.” Spearheaded by Alastair Paterson, CEO and co-founder of Harmonic Security, the initiative aims to build sustained momentum for cybersecurity innovation by connecting startups, investors, and enterprise leaders.

The UK government has already shown support for the effort and is expected to host a private gathering next month involving chief information security officers (CISOs), venture capital firms, and startup founders. The goal is to create meaningful connections that can drive funding, partnerships, and long-term growth within the sector.

Paterson explained that the cyber flywheel concept is inspired by successful ecosystems such as Israel’s cybersecurity industry, where startups are able to scale rapidly, secure funding, and exit successfully. These exits, in turn, produce experienced founders and investors who reinvest in the next generation of companies, creating a self-sustaining cycle of innovation. While the UK has a strong foundation of skilled talent and innovative ideas, Paterson noted that many startups struggle to scale into globally competitive businesses. He pointed out that although companies like Darktrace have achieved significant success, there have been relatively few high-value exits in recent years, with only a handful of cybersecurity startups surpassing £100 million valuations.

One of the key challenges, according to Paterson, is that UK startups often delay expanding into the US market. He believes this hesitation can limit growth opportunities, as the US remains the largest and most competitive market for cybersecurity solutions. Without early expansion, many UK startups risk becoming regional players that are eventually acquired rather than evolving into global leaders.

To address these challenges, the cyber flywheel initiative focuses on fostering direct collaboration between founders, investors, and potential buyers. The first event, held at London’s National Theatre, brought together dozens of participants and resulted in valuable connections that have already led to new business opportunities and partnerships. Ongoing engagement through a dedicated networking group continues to support these relationships.

Following the initial event, 65 participants signed an open letter urging the government to create more favorable conditions for cybersecurity startups. Key recommendations include increased government procurement from startups, improved access to resources from the National Cyber Security Centre (NCSC), targeted tax incentives, and greater investment in emerging technologies.

The upcoming event, to be hosted by the Foreign, Commonwealth & Development Office, aims to deepen collaboration by bringing more CISOs into discussions around design partnerships with startups. Paterson emphasized the importance of fostering a national growth mindset, encouraging stronger support for entrepreneurship and innovation. He believes that with the right backing from government, investors, and industry, the UK can build a thriving cybersecurity ecosystem capable of competing on a global scale.
