MijnOverheid

MijnOverheid (Dutch for 'MyGovernment') is the Netherlands' centralised digital communications portal through which citizens receive official correspondence from government bodies including the tax authority, municipalities and social-security agencies. Launched in the mid-2000s under the Dutch Ministry of the Interior, it processes millions of messages annually and serves as a primary channel for legally significant official notifications. Access is authenticated via DigiD, the national digital-identity system. The portal is operated on infrastructure hosted by Solvinity, a Dutch cloud provider contracted to maintain government-grade data residency and security standards.

MijnOverheid's hosting arrangement with Solvinity became a direct factor in the Dutch government's decision to block Kyndryl's EUR 100m acquisition of Solvinity on 26 May 2026. Dutch minister Willemijn Aerdts cited risk to the public interest: Solvinity's infrastructure underpins not only MijnOverheid but also DigiD itself, meaning that a US-owned acquirer would bring these systems within reach of the US CLOUD Act, which allows American authorities to compel data disclosure across jurisdictions. The Investment Screening Bureau's block was the first time the Netherlands had ever stopped a US deal under that mechanism . The case established that cloud hosting of public-interest government portals can constitute a national-security interest sufficient to override a cleared antitrust review.
