Why scope trips up so many assessments
Before you answer a single technical question in Cyber Essentials, you must agree your boundary of scope with your Certification Body. Under the April 2026 Danzell updates (IASME) and the NCSC Requirements for IT Infrastructure v3.3:
- Every legal entity must be named: You must list the legal name, registered address and company number of every entity covered by the certificate. These appear on IASME’s digital certificate platform.
- Cloud services can never be excluded: Any online service accessed with company credentials or a business email address that stores or processes your organisation’s data is automatically in scope.
- End-user devices cannot be excluded: A scope that leaves out staff laptops, desktops or phones that access company data is not acceptable.
- Exclusions need network segregation: If you exclude an older machine or a separate business unit, it must sit on a segregated network (behind a firewall or Virtual Local Area Network (VLAN) with no internet connection or path to in-scope systems) and you must explain that separation to the assessor.
