The record

Purpose: The hardware or virtual appliance scans internal and internet-facing network assets for vulnerabilities and compliance issues.
Scan types: It supports VM, PC, WAS, network mapping, and PCI compliance scans.
Environments: It extends the Qualys Enterprise TruRisk Platform into on-premises environments and assesses systems and devices on the network, including IoT devices.
Asset coverage: It supports IP-based assets across on-premises, cloud, and hybrid environments, including IPv6 and vault/HSM integration.
Deployment options: Qualys offers physical, virtual, cloud, and container scanner appliance environments.
Virtual appliance licensing: Each purchased virtual scanner license allows one active appliance, and the appliance extends an existing Qualys Enterprise TruRisk Platform subscription rather than operating as a standalone solution.
Supported virtualization: Virtual scanner distributions are listed for platforms including VMware, Hyper-V, OpenStack, AWS, Azure, Google Cloud, Oracle Cloud, Alibaba Cloud, Nutanix, KVM, Proxmox, and OpenShift.
Platform limitation: Scanner Appliance does not support ARM-based infrastructure, including Apple products with M1 and M2 chipsets.
Security: Qualys states that scanners have no listening ports or services, all ports are closed, and communication to the Qualys platform uses HTTPS to designated and authorized endpoints.
Management integration: Scanner appliances integrate with the Qualys Cloud Platform for centralized management, reporting, and scan-result analysis.
Updates: The product page says scanner appliances receive automatic updates to vulnerability signatures, security checks, and patches.
Who it is for: Qualys describes the solution as suitable for organizations with large network infrastructure or regulatory requirements for internal scanning.
Platform support: Virtual scanner distributions are available for platforms including VMware, Hyper-V, OpenStack, KVM, Proxmox, and cloud providers; full support is limited to qualified platforms and versions.
Subscription requirement: The virtual scanner is an extension of an existing Qualys Enterprise TruRisk Platform subscription and is not a standalone solution; each license allows one active virtual scanner appliance.
