Top 50 cybersecurity companies in the Netherlands

Tamtam tracks 55 cybersecurity companies headquartered in the Netherlands. This list ranks the 50 largest by number of employees on LinkedIn, led by Getronics, KPMG Nederland and Centric.

πŸ‡³πŸ‡± Netherlands50 companiesUpdated Nov 12, 2026

The cybersecurity companies in the Netherlands on this list are predominantly large IT services and consulting firms. Many provide comprehensive digital solutions, cloud services, and infrastructure management. Key players include Getronics, a global technology solutions provider, and Irdeto, a leader in digital platform cybersecurity.

A notable pattern among these companies is their geographical spread across various Dutch cities, rather than a single cluster. While Amsterdam and Hoofddorp feature prominently, other significant headquarters are in Amstelveen, Gouda, Arnhem, Utrecht, and Delft, indicating a decentralized distribution of these larger IT and cybersecurity entities.

How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
