PortAura is a native macOS utility that shows which processes are listening on which ports, where they’re exposed, and what has changed since your trusted baseline. It helps you understand local services without digging through Terminal commands. Everything runs locally on your Mac.

appreciate that this stays local instead of shipping port/process data to a cloud dashboard - for a security tool that's the right default. curious how the baseline gets set initially though: is it a manual "snapshot now" action, or does it auto-baseline after first install, since a bad first snapshot (taken while something unwanted is already running) would make the whole diff useless.
@galdayan Good question — PortAura does not auto-baseline on first install.
The baseline is only created when the user explicitly reviews and confirms the current listening state, and updating it later also requires confirmation. That’s intentional for exactly the reason you pointed out: I don’t want the first snapshot to be silently treated as trusted.
That said, PortAura is a change detector rather than a malware scanner, so if someone manually confirms a bad state, it would still become part of the baseline. Your point makes me think the first-baseline flow should probably make that trust decision even more explicit. Thanks for calling it out.

@efrem_lee that's a sensible tradeoff honestly - a manual confirm step is a better default than trusting whatever's running at install time. makes me think the confirm screen itself could show a quick "does this look normal" checklist (unexpected listeners, unfamiliar process names) rather than just a raw list, so the human doing the confirming has some help catching the bad state before it gets baked in as trusted.

@efrem_lee makes sense, and honestly that's the right scope - a change detector that flags "this is new" is more useful long-term than a scanner trying to guess good vs bad on its own. good luck with the update.
