The IT Security and Compliance security service provides Internet Remote Scanners that perform fast and efficient scanning at the network perimeter. Scanner Appliances extend the same scanning capabilities to the internal network. Installed in minutes and requiring no maintenance by the user, the hardened Linux appliance needs no special firewall configurations to obtain new vulnerability signatures and other software updates.
With scanner appliances, you can perform network security audits and network mapping behind the corporate firewall, on the host and devices within your enterprise. The scanner appliances places inside the corporate network are fully integrated with the service's global platform. Scanning for vulnerabilities and network mapping is available for all subscriptions.
It is recommended that you scan only devices within firewall boundaries. Scanning through a firewall may impact scan results. See Scanning and Firewalls for more information.
