A quick overview of the steps that a service put forward for an off-the-shelf (commodity) assurance assessment will undergo

Where assessment of a service will be delivered by an NCSC approved company with certification by the NCSC:

  1. Select a suitable Service Requirement.

  2. Talk to one of our CAS evaluation partners and confirm the suitability of the Service for assessment against the selected Service Requirement.

  3. The evaluation partner submits a CAS Acceptance Recommendation Report.

  4. We confirm the suitability of the Service against the Service Requirement.

  5. The CAS evaluation partner proceeds with the assessment.

  6. We review the assessment deliverables.

  7. The NCSC then produces an assessment Statement and Certificate for the successful services and sends that to the CAS evaluation partner.

  8. The evaluation partner delivers the CAS Certificate to the Service Provider.

  9. We update our website to add the successful certified service.
