The Initiate Scans From is an attribute of an Integration and an indication of where the activity (a data load or orchestration) will take place.
- SaaS = ZeroNorth Platform indicates that the scan will happen in ZeroNorth’s AWS VPC
- Onprem = Customer’s Environment indicates that the scan happens on-prem (i.e., customer’s data center or VPC)
The Initiate Scans From setting can be overridden at the Policy level.
