Cyber Essentials Guide – An in-depth look at passing first time.

This Cyber Essentials guide has been written by a Cyber Essentials Lead Assessor and is intended to help those companies wishing to certify with Indelible Data Limited. The purpose is to help clients get the submission right at the first attempt and save time. Though this document has not been issued by, or on behalf of, The National Cyber Security Centre (NCSC) or the NCSC’s sole Cyber Essentials Partner, IASME, it has been compiled by a Lead Assessor with extensive knowledge of the scheme. Information in this Cyber Essentials Guide is subject to change without prior notice.

Completing the Cyber Essentials question set can, at first, appear daunting. This guide helps take away the uncertainty, guide the applicant through the Cyber Essentials Basic Level submission process and is split into 3 sections:

      1. Describing the journey from initial enquiry through to final submission and subsequent assessor feedback
      2. Helping to scope the assessment
      3. Addressing the requirements of the Cyber Essentials questions and explaining areas where most applicants either misunderstand or simply do not respond to the questions as comprehensively as expected.

The aim is to ensure submissions are not made until the applicant is confident all the questions have been completed correctly – hence increasing the chances of passing the submission first time!

Note: It is tempting to just jump to section 3 and address the questions, however if you have not defined the scope correctly, then the questions cannot be assessed properly.

Further helpful Cyber Essentials resources can be found at the NCSC's Website.
