Fragmentation is the silent killer of your security program. Sounds serious, right? Well, it is. After more than a decade of research, innovation, and investment in the cybersecurity industry, the "Detection Deficit" between attackers and defenders is near an all-time high and trending wider.

In this paper we'll take a look at the issues and lay out a path toward better security through better unity, one that cuts the detection deficit with a cohesive, intelligent defense.
