On-Prem Data Security in the AI Era: Why It's Time to Modernize with DSPM
Zscaler, Tuesday, August 4th, 2026
Zscaler argues on-premises sensitive data needs DSPM as it flows into AI workflows.
Zscaler notes that despite cloud migration, much of an enterprise's most sensitive data still lives on premises in file shares, NAS environments, and legacy repositories.
That data increasingly flows into AI workflows, is accessed remotely, shared through SaaS, and indexed by assistants.
Legacy pattern-based security approaches were not designed for those movement paths. Zscaler argues data security posture management is now needed for on-premises estates rather than only cloud.
