There’s a popular business quote that goes something like, “if you can’t measure it, you can’t manage it.” But when it comes to physical security it’s not so easy – because the most meaningful measure is in what does not happen. How many intruders were discouraged and denied? How many secrets and goods were not stolen? And how many damaging data breaches didn’t happen? In demonstrating the value of a physical security team, can we get to a point where these values could be measured, tracked, and have rewards based on it? While for now that may be wishful thinking, maybe we’re a lot closer than you might think. The growth of metrics, analytics, and machine learning in physical security is heading us in that direction.
