Choose the right perspective
Match the person's footprint to yours, since securing a few headquarters offices differs from running security across hundreds of sites in several countries. Also decide whether your question is mainly about guarding and operations or about security systems such as access control and video, and pick someone whose roles centered on that side.
Questions to take into the conversation
- 01How do you decide which sites get staffed guards and which rely on access control, cameras and remote monitoring?
- 02How do you structure contracts and oversight for outsourced guard services?
- 03Which measures do you report to executives to show the physical security program is working?
