Your security site plan can have a lot of moving parts. For critical infrastructure sites (i.e., power plants – nuclear, gas, electrical or solar, petroleum refineries, data centers, etc.), it’s important to know what’s happening inside and outside, regardless if you’re onsite or not. Not knowing what’s going on is, to put it mildly, discomforting. Knowing something has happened without being sure exactly what that might be can be just as frustrating.
