scanless

scanless is a Python command-line utility that performs port scans anonymously by routing scan requests through third-party online port scanning services rather than sending packets directly from the operator's IP address. It aggregates results from multiple web-based scanners to provide port status information while keeping the operator's true network address hidden from the target. Penetration testers and red team operators use scanless during the initial reconnaissance phase when they need to identify open ports without triggering the target's intrusion detection systems or revealing their infrastructure. The tool is particularly useful for stealthy external reconnaissance and for validating firewall rules from an outside perspective without directly touching the target network.
