Zscaler's expansion within existing enterprise accounts—contributing 70% of incremental revenue—reflects high customer lifetime value and embedded switching costs in large, complex networks. Once deployed inline as a proxy across a distributed workforce, ripping out Zscaler requires re-architecting security infrastructure, making renewals and upsells the path of least resistance. This land-and-expand dynamic compounds ARR faster than customer count growth alone.
