Static guarding is strongest when someone must continuously control access, observe activity or respond immediately. Key holding and alarm response suit sites that need a trained attendance after an activation without placing employees at risk. Some estates need a blend of both.
01
Choose static guarding when presence is part of the control
A resident officer can verify people and vehicles, manage keys and contractors, monitor alarms, conduct patrols and act as the site’s immediate security point. It is appropriate where gaps in presence would materially change the risk.
02
Choose key holding when the response follows an activation
A key holder can attend an alarm, assess the cause where safe, coordinate with nominated contacts or contractors and document the outcome. The service should define response expectations, access controls and escalation before the first call-out.
03
Use a blended model for peaks and critical windows
Some sites need guarding at the gate during operating hours, followed by professional key holding and alarm response overnight. The right model follows risk and workflow rather than a supplier’s preferred product.
- Map where immediate intervention is genuinely needed
- Confirm which alarms require a professional attendance
- Price the whole operating model, not only the hourly rate
- Define evidence and escalation for every call-out
