AI Agents Force Enterprise Security Overhaul as Vendors Race to Book Agent ARR

The vendor disclosures point to a structural shift rather than a cyclical one: security budgets are being redirected toward identity and runtime controls precisely because agents operate inside the perimeter with legitimate credentials, making traditional network and endpoint boundaries less decisive. The revenue mix is the tell — AI-attributed ARR is now material enough to be broken out separately, which changes how these companies are valued and how they position against each other. The open question is whether that attribution holds up once agent deployments move from pilots into production, or whether it proves to be a reporting artifact.
