European Cybersecurity Startup Radar 2026

Europe’s cybersecurity innovators, mapped across six markets

Europe has nothing to hide when it comes to cybersecurity innovation. Across the continent, a new generation of startups is building the technologies that will defend tomorrow’s organizations, yet the European market is anything but uniform. It is a patchwork of specialized ecosystems, each shaped by its own talent pools, regulation, and industrial heritage. For this edition we analyzed 729 startups, scale-ups, and unicorns across six markets, namely Belgium, France, Germany, Luxembourg, Switzerland, and the United Kingdom, and brought our national findings together into a single view, so you can explore each market in depth and understand how they compare.

Why a European perspective

For too long, the narrative around cybersecurity innovation has been written elsewhere. Europe’s reality is more nuanced, and more promising, than the headlines suggest. The continent is not one market but many: a landscape of specialized ecosystems, where each country has carved out its own strengths. Some lead in deep technological research, others in regulatory-driven solutions, and smaller markets often punch well above their weight in focused niches. What unites them is a shared momentum, driven by rising threat levels and a converging regulatory agenda, from NIS2 to the Cyber Resilience Act, that is turning security from a cost into a strategic imperative. This radar exists to make that diversity legible: to show not just where the startups are, but what makes each ecosystem distinct.

Belgium

Belgium’s cybersecurity ecosystem is small but steady, with a distributed landscape increasingly driven by the Flemish north around Antwerp and East Flanders, while Brussels holds firm as a central hub. It remains a predominantly early-stage market with limited scale-up maturity, yet AI is already widely embedded across the majority of startups. The ecosystem’s clearest strengths lie in future-proof data protection including advanced cryptography, identity and access management, vulnerability management, and streamlining governance, risk, and compliance, and it has produced a homegrown unicorn in Aikido.

France

France’s cybersecurity ecosystem is in full effervescence, adding a record wave of new startups even amid economic and technological uncertainty. The country combines strong state and Bpifrance backing with a strong deep tech base, and it stands out for its work in securing AI and homomorphic encryption, home to unicorns Ledger and Zama. Its leading categories in 2026 are Governance & Risk Compliance, Vulnerabilities, and Data Security, while Paris remains the central hub alongside fast-growing regional poles such as Lyon.

Germany

Germany’s cybersecurity ecosystem is entering a consolidating phase, where innovation is increasingly driven by European regulation rather than by new attack techniques. Startups here are international by design, addressing global markets from day one and turning compliance with NIS2, DORA, and the Cyber Resilience Act into a core product capability. The strongest momentum sits in AI security, automated compliance, and identity-centric access, while the ecosystem clusters around three regional hubs: Berlin, North Rhine-Westphalia, and Bavaria.

Luxembourg

Luxembourg’s cybersecurity ecosystem is small but remarkably fast-moving, with three quarters of its startups founded since 2022 and an average company age of just 3.1 years. The country combines a compact, pro-business support system (from the Luxembourg House of Cybersecurity with its LUCYA accelerator to Luxinnovation’s Fit4Start program) with particular strengths in post-quantum cryptography, digital trust, and secure data exchange. Its startups cover nearly all NIST CSF 2.0 pillars, target enterprise clients in regulated sectors from day one, and internationalize early, with Germany, France, and Belgium acting as natural first expansion corridors.

Switzerland

Switzerland’s cybersecurity ecosystem is defined by data protection, neutrality, and trust, with startups pursuing international growth strategies primarily focused on European markets. Creation is steady rather than explosive, and the market is structured around strong incubation platforms, led by Zurich and complemented by hubs in Vaud, Geneva, Zug’s Crypto Valley, and Ticino. Its clearest strengths lie in secure data exchange, data security, and network security, alongside a notable deep tech presence in areas such as data privacy and privacy-preserving technologies, and it has produced a homegrown unicorn in Acronis.

United Kingdom

The United Kingdom is one of Europe’s largest and fastest-growing cybersecurity startup markets, adding an unprecedented wave of new entrants in 2026. London remains the central hub, yet activity is increasingly dispersing to regional ecosystems, with the South West standing out among this year’s new arrivals. British startups are strongest in Governance & Risk Compliance, Detection & Response, and Application Security, and AI adoption has surged, though finding customers and market access remain the ecosystem’s biggest hurdles.

Methodology

All six radars are built on the same analytical foundation. To qualify as a startup, a company must be headquartered in the respective country, employ fewer than 35 people, be seven years old or less, and generate less than 50% of its revenue from consulting activity. Applying identical criteria across all markets is what makes the radars genuinely comparable: the differences you see between countries reflect real characteristics of each ecosystem, not differences in method.

In France, the United Kingdom, Belgium, and Switzerland, the analysis additionally covers scale-ups and unicorns, more mature players that have outgrown the startup criteria through funding or revenue but remain a defining part of their national ecosystems. In total, the 2026 editions analyze 729 companies across the six markets.
