portscan

Port scanning with built-in OS tools probes target hosts to identify open ports. It uses native utilities across Linux, macOS, and Windows to probe common or user-specified ranges, outputting HOST:PORT status with an optional service guess and a concise summary.

Yes, you can scan multiple targets and specified port ranges without third-party software. The scan uses native OS tooling to probe targets concurrently, respecting per-port timeouts to speed up results while returning a list of open and closed ports.

Port scanning works across Linux, macOS, and Windows. It applies native OS tooling on each platform to probe target hosts, ensuring quick reconnaissance and vulnerability assessment without requiring platform-specific third-party software.

Using built-in OS tools to port scan test hosts is an effective way to map open services. Security auditors can quickly identify open ports and optional service guesses to establish baseline configuration checks without additional software.

Limitations of built-in OS tool port scanning include per-port timeouts and constrained design. While it supports concurrent scans for speed, it relies on native utilities rather than advanced third-party scanners, focusing on quick reconnaissance over deep vulnerability exploitation.
