DENIC eG is the registry for the .de top-level domain. It maintains the registry database and the DNS infrastructure for .de, and offers services such as DNSSEC, registry lock, escrow and whois queries. The company's homepage lists ISO 27001 and ISO 22301 certifications. It is delivered as registry infrastructure and services for registrars, not as software that organisations install.
DENIC is a cooperative registered in Frankfurt am Main, with its registered office at Theodor-Stern-Kai 1. The sources reviewed do not name a majority owner, and the cooperative is organised around its members. Its privacy statement names DENIC eG as controller, states that processing follows the GDPR and the German Federal Data Protection Act, and names German entities for some services. The homepage describes its DNS infrastructure as globally distributed, and the location of registration data is not stated. A European organisation can treat DENIC as a German, EU-based registry, but should check the data handling for each service it uses.
