In a world driven by digital transformation, physical security still sits at the foundation of protecting people, property, and operations. If an intruder can access the site, every other security layer becomes harder to protect. That is why perimeter security is not just a checklist item. It is the first line of defense and the first opportunity to prevent an incident before it becomes a disruption. This is especially true for critical infrastructure and wide-area outdoor facilities. These sites often span large open perimeters, include multiple access routes.
