The secure and recommended approach to validate whether firewall restrictions are causing CSPM failures is toconfirm that CrowdStrike’s documented IP addresses are allowlisted. Falcon Cloud Security relies on outbound API connectivity to cloud providers, and blocked traffic can disrupt asset inventory collection and IOM detection even if registration succeeds.

CrowdStrike publishes required IP ranges and endpoints for each cloud region. Verifying firewall rules against this documentation is alow-risk, best-practice troubleshooting stepthat preserves security controls while validating connectivity assumptions.

Opening firewalls broadly is insecure and unnecessary, and dismissing firewall-related causes without verification can delay resolution. Therefore, the correct answer isCheck that you have allowlisted the IP addresses provided in the public-facing CrowdStrike documentation.
