deSEC is a managed DNS provider run as a nonprofit in Germany. Its focus is security: DNSSEC and DANE are central to the service, and it supports a wide range of modern record types. The software behind it is open source.

Queries are answered from a global network of servers for low latency, and the service is free of charge. For domain owners, deSEC is a European alternative to the commercial American DNS providers, and it suits anyone who wants properly signed zones without a bill.
