About the Guide

The ST4S vendor guide covers the ST4S assessment framework and provides guidance and information regarding:

  • the assessment process and results
  • the questions included in the ST4S assessment questionnaire and the minimum acceptable responses
  • links to relevant industry standards
  • the criteria used to determine a compliant vs. non-compliant response, with critically important criteria marked with a hash (#)
  • the initial categorisation of products and services based on assessment tiers
  • how the assessment results will be shared with participating member organisations.
