The CSPM module in Cloud Advisor analyzes the entire network connectivity chain - including load balancers, NAT, public IP addresses, security groups, and other objects - to determine which resources are accessible from a wide range of external IP addresses. Now, to further verify public accessibility, the platform also performs external scanning: it connects to potentially open ports from outside and checks their actual status - whether the port is open or closed. This allows Cloud Advisor to identify publicly exposed applications - combinations of an IP address and an open port through which applications are accessible from the internet.
