The Cyber Domain will ensure a coordinated community effort to increase broad visibility of cyber risks through consistent data and information sharing.


The Cyber Domain is stewarded by the Cybersecurity and Infrastructure Security Agency (CISA) at the Department of Homeland Security (DHS). It was formally stood up in January 2020 to bring community stakeholders together to manage the development and adoption of domain content and exchanges. As the nation’s cybersecurity and infrastructure risk advisor, CISA is uniquely positioned to partner with those stakeholders to develop risk-informed decisions based on consistent cyber data and information sharing.
