Ports and Protocols

Cortex® Xpanse™’s Internet Sensing platform detects protocol-validated services on the IPv4 space of the Internet.
Cortex® Xpanse™’s Internet Sensing platform detects protocol-validated services on the IPv4 space of the Internet through a series of specialized payloads that target specific port-protocol pairs. Below is a list of standard port-protocol pairs on which Cortex Xpanse checks for active services throughout a standard global scan. Due to the nature of Cortex Xpanse’s Internet Sensing platform, some additional port-protocol pairs not listed here may be checked for active services during some scans. Additional port-protocol pairs may be checked for your Expander instance depending on the details of your subscription.
