The posture-first approach revealed its limitations as the endpoint attack surface exploded. The industry faced visibility gaps and realized you cannot harden what you cannot fully see. The posture-first approach wasn’t wrong. It was incomplete. As the endpoint attack surface exploded, the industry realized that you cannot harden what you cannot fully see. Limited visibility hindered effective hardening, driving the shift toward behavioral detection as an operational necessity.
AI security is at the beginning of that same arc. The teams that recognize it now get to skip the painful middle chapter.
The endpoint era’s hard-won lesson
The first generation of endpoint security asked answerable questions: Is antivirus installed? Are patches current? Does the configuration match the baseline? For a while, answering those questions felt like enough.
Then the surface expanded. Laptops left the perimeter. Zero-days made signatures irrelevant at the moment they mattered most. The industry responded by building tools that stopped asking “does this file look bad?” and started asking “what is this process actually doing?”.
