How does the Europe cybersecurity startup ecosystem compare to other regions?
Europe accounts for 3 of the cybersecurity startups in our tracking dataset for Q2 2026. This geographic view filters the broader sector rankings to help investors focused on Europe-based deal flow identify engineering acceleration patterns within their target geography. Regional concentrations often reflect local regulatory environments, talent pools, and investor networks that shape startup trajectories differently from global averages.
How is startup geography determined in these rankings?
We derive startup geography primarily from the GitHub organization profile location field, supplemented by a manually curated enrichment database of known startup headquarters. This means startups without a public GitHub location may appear in our global sector rankings but not in geographic filters. The geographic classification uses broad regions (Europe, etc.) rather than city-level granularity to provide meaningful sample sizes for comparison.
