Operational Decision Support
Decision-support prompts for common operational scenarios, aligned to UK security industry practice. These guides inform professional judgement — they do not replace company policy, assignment instructions, client requirements or professional training. Developed under the operational direction of Roy Longley, Group Head of Risk & Compliance, Fullerton Group.
Precedence: Company policy, assignment instructions, client requirements, site emergency procedures and recognised UK guidance always take precedence over the information in GuardAssist. This resource supports — it does not replace — professional judgement or training.
