The Cyber Resilience Review (CRR) is a complimentary, voluntary program provided by the Cyber Security Evaluation Program (CSEP) within the Department of Homeland Security to develop an understanding of an organization's operational resilience and ability to manage cyber risks to its critical services and assets. The CRR pays special attention to protection and sustainment practices with their ten established key domains of cyber resilience, generating a report that summarizes observed strengths and weaknesses in each domain.
