What is the purpose of a Cyber Essentials Plus vulnerability scan?

The vulnerability scan is utilised on two steps of the Cyber Essentials Plus certification process (scans are not used as part of the Cyber Essentials certification process, which relies on a self-assessment questionnaire).

Initially, vulnerability scans are used to assess all the external-facing devices used in the infrastructure (firewalls, routers, servers, services etc.) and then later on the internal vulnerability scan to assess the sampled endpoints.
