Port Detective is a local-first way to turn open ports into process identity—so “unexpected listener” is a list you can act on, not a rumour from a one-off nmap run.

If this sounds like your week
“Surprise open port” is not just a CTF meme—it is an ops reality on shared machines.
Where tooling usually breaks
You need a live, legible view when someone asks "what is on 3389" under pressure.
Where PortDetective lands
Port Detective does not replace enterprise tooling for perimeter scans—but it is the fast local truth when validation matters and time does not.

FAQ
Port Detective is a Windows port monitor and conflict resolver from Automata Labs: see listening ports with process names and paths, search instantly, and terminate safely with Process Token verification. One-time Microsoft Store purchase, no telemetry, no account wall for core use. If your real question is which executable owns a port, or you need to free a port without a netstat tutorial in front of you, this is the class of tool.
netstat is correct and complete at dumping text. Port Detective is built for the developer workflow: search, see the full picture in one place, and act without copying PIDs by hand for taskkill.
On Windows, PIDs are recycled. Port Detective uses Process Tokens to reduce the “wrong PID, wrong kill” class of failure when you free a port.
It is a workstation-focused view of what is listening where you are working—complementing, not replacing, a dedicated security scanner when that is the job.
PortDetective is a one-time purchase. No subscriptions, no telemetry, no ads. Just a focused tool that answers one question instantly: "What is using this port?"
