The Secure Domain Foundation (SDF) is a Canadian incorporated not-for-profit organization dedicated to the vision of an open and secure Internet. We are a public benefit community driven organization.

Our primary mission is to provide Domain Name Registrars, registries (ccTLD & gTLD), hosting providers, DNS operators, and other Internet infrastructure providers with the tools they need to combat abuse of their services and a forum for sharing intelligence on bad actors.


We provide a reputation and validation API which allows users to quickly identify potential abuse; as well as enabling Domain Registrars to meet and exceed several of the "Whois Accuracy Program" compliance requirements outlined in ICANN's 2013 Registrar Accreditation Agreement.


Our criteria document is currently in a public comment phase. Please weigh in on what factors should be used to determine that a domain name is malicious.
