Declaration of Conformity

What Is a Declaration of Conformity?

In cybersecurity and information security, a Declaration of Conformity (DoC) is a formal document in which an organization attests that its security controls, processes, or products meet the requirements of a specific standard or framework — such as ISO 27001, SOC 2, or the NIST Cybersecurity Framework. It serves as a self-declaration of compliance and is often used when a full third-party audit is not required or as a precursor to formal certification.

Description

A Declaration of Conformity allows organizations to formally assert that they have implemented the controls required by a given standard. Unlike a certification issued by an accredited body, a DoC is self-issued — meaning the organization takes responsibility for the accuracy of the claim. It is commonly used in vendor assessments, procurement processes, and regulatory filings where a buyer or regulator needs documented evidence of a supplier's security posture without commissioning a full independent audit.

Usage and Examples

A software vendor responding to an enterprise procurement questionnaire might issue a Declaration of Conformity stating that their product meets the requirements of ISO 27001 Annex A controls. Similarly, a cloud service provider might provide a DoC asserting alignment with the NIST Cybersecurity Framework as part of a government contracting process. In the context of the EU Cybersecurity Act, certain ICT products and services can use a Declaration of Conformity to self-certify against defined security requirements. Organizations should be aware that a DoC does not carry the same weight as an independently audited certification and should be validated accordingly during third-party risk assessments.
