To avoid placing too much load on your scanning machines, you can limit the maximum number of concurrent scans that they can run. For newly added scanning machines, the default scan limit is 1. If the scanning machine has enough RAM and CPU cores, you can increase the scan limit. For more information, refer to the System requirements.
This page explains how to configure fixed scanning machines as part of a standard deployment. For information on how to use cloud-based auto-scaling scanning, see the Managing auto scaling scan resources page.
