Cybersecurity directory
Early-Stage Cybersecurity Startups in Europe
Cybersecurity covers the tools and services that protect software, data, identities, and infrastructure from attack. Europe is a strong base for the sector thanks to deep technical talent, strict regulation that rewards privacy by design, and national agencies that set high assurance standards. Many of the most trusted security teams in the region build for global customers from day one.

Why cybersecurity now
Attacks keep rising as more business runs on cloud platforms, APIs, and AI systems, so demand for defensive technology continues to grow. European rules on data protection and resilience push organisations to invest in mature security tooling. Buyers increasingly want vendors that keep sensitive data inside the region, which favours homegrown providers.
How we choose these companies
A public directory of early-stage European cybersecurity startups. We aim to list every company that fits, not a hand-picked few. Here is exactly what that means, and why:
- European: headquartered in Europe (EU, EEA, UK, Switzerland and nearby). We go by where a company is based, not just where it sells, because this is a map of the European ecosystem.
- Early-stage: founded in the last 5 years. That is where the new ideas and the most active part of the ecosystem are; established household-name scaleups are a different list.
- A real product company: builds a scalable technology product or platform. We leave out agencies, consultancies and local service businesses, which do not follow the same path.
- Independent: a standalone company, not a subsidiary or brand of a larger corporation.
- Active: currently operating, with a live website. We re-check regularly and remove companies that shut down, get acquired, or move out of scope.
We list only public information about what each company does. We deliberately do not track or show fundraising: who is raising, who is investing, or how much. This is a directory of companies, not a deal database.
