A cybersecurity self-assessment is a structured review of an organization’s security controls, processes, technology, governance, and risk. It may be completed for internal planning, a customer security questionnaire, an insurer, a regulator, or a compliance requirement. A useful assessment identifies what is in place, what evidence supports it, where gaps exist, and which actions should be prioritized.
