Building Trust in the Supply Chain Since 2016

Our vision is a supply chain where open source is delivered with trusted and consistent compliance information. Our mission is to make that happen.

This Is Where You Will Find:

  • The ISO/IEC standard for open source license compliance programs
  • The industry standard for open source security assurance programs
  • The community that powers these standards

OpenChain ISO/IEC 5230:2020 is the International Standard for open source license compliance. This is a simple, effective standard suitable for companies of all sizes in all markets. It is developed openly by a vibrant user community and freely available to all. It is supported by free online self-certification, extensive reference material and official service provider partners.

Did You Know…

20% of German companies with over 2,000 employees have already implemented ISO/IEC 5230.

ISO/IEC 5230 Conformant Programs Announced Via Our Website


We also maintain the OpenChain Security Assurance Specification, a standard for open source security compliance. This is also a simple, effective sister specification to our license compliance specification, and it is suitable for companies of all sizes in all markets. It is expected to become an ISO/IEC standard later in 2023. You can adopt the standard today and your conformance will be valid for the ISO/IEC version as well. The first company to announce OpenChain Security Assurance Specification conformance is Interneuron in the United Kingdom.
