How does CISGuard compare to Qualys?

More context

The architectural split is the crux of this comparison. A SaaS-only platform requires that scan data and posture information leave the customer estate and reside in the vendor's cloud. That model is efficient and low-maintenance for many organizations, but it collides with data-residency rules and network-isolation requirements that some regulated and sovereign environments impose, where sending configuration detail to an offshore multi-tenant service is either prohibited or heavily constrained.

Deploying inside the customer's own environment keeps scan results and evidence under the customer's control and within the required jurisdiction, which is often what makes a compliance program viable in the first place for GCC and EU-residency mandates. Beyond residency, reports authored to match how auditors read a framework spare the compliance team the recurring effort of reshaping general-purpose product output into acceptable evidence.
