DigiD

DigiD provides a secure authentication mechanism that allows Dutch citizens and businesses to log in to online government services such as tax filing, social benefits applications, and healthcare appointment systems. It functions as a national digital identity solution, verifying users’ identities before granting access to portals operated by various public sector organisations. By enabling single sign‑on across multiple services, DigiD reduces the need for separate credentials and streamlines interactions with the state. The system is used for both personal and professional dealings with the Dutch government.

The service underpins critical digital services used for taxation, benefits, healthcare and other public functions, as highlighted in incident reports describing its temporary unavailability during a large‑scale DDoS attack. DigiD forms a key component of the Netherlands’ e‑government infrastructure, supporting the digital delivery of public administration. Its operation is essential for maintaining continuity of online government access for a broad segment of the population.

DigiD specialises in delivering a trusted, government‑backed authentication service, positioned as the national login mechanism within the public sector. It is distinguished by its integration with Logius’ ICT services and its participation in an anti‑DDoS coalition, which aims to strengthen resilience against volumetric threats. Although the system employs robust DDoS protection measures, the 2025 incident demonstrated that exceptionally high traffic volumes can overwhelm existing defences and cause service disruption. DigiD is operated by Logius, the ICT service provider for the Dutch government, which oversees its technical delivery, security maintenance, and ongoing improvement.

Structurally, DigiD is not a separate legal entity but a service offering of Logius, which is part of the Dutch government’s ICT service organisation; no further parent or subsidiary details are specified in the available information.
