Free Port Scanner

CNET Editors' review

Hackers are like unruly sailors on liberty when it comes to open ports: You can't keep them out, and they leave disaster in their wake. Protecting your ports is essential to keeping your system safe, and that starts with knowledge of your system's ports and whether they're Wide Open or Closed for the Duration. Free Port Scanner is just the tool for the job. This simple freeware from Network Security Audit Software (Nsasoft) thoroughly scans and tests your system's ports. It can reveal vulnerable access points so you can take action to close them to attackers.

Free Port Scanner is a simple tool with a simple interface: just Scan and Stop buttons and fields for displaying IP address and specifying TCP ports. A checkbox marked Show Closed Ports is selected by default. Unchecking it shows only open ports, a handy option for focusing on problems. We pressed Scan, and a blue progress bar began tracking the job. But Free Port Scanner doesn't just quickly ID your ports; it probes each of them thoroughly and persistently for weaknesses, and it doesn't list results in the main window until it's satisfied the port is closed or open. The scan took several minutes to complete, displaying IP Address, Port Number, Description, Port Name, and Port Status. As we expected, all our ports showed Closed under Port Status, but it's still nice to be reminded of it. If one or more of your system's ports is open, look to your system security and software. Then run Free Port Scanner again, and again if necessary; as many times as it takes to verify your system's safety.

If hackers are like the proverbial drunken sailor when it comes to open ports, good network security tools are the Shore Patrol, preventing trouble by the most effective measure, closing the port. Free Port Scanner won't secure your system; it's the early warning you need to do the job yourself, based on your hardware, software, and security tools. Highly recommended for all users.

    "Scanner Works but Undesirable Junk is Downloaded Too!"

    March 23, 2013  |   By wwgorman

    Version: Free Port Scanner 3.1.1

    Pros

    It does scan the ports and advise you if they are open (vulnerable) 0r closed (safe).

    Cons

    So many other items came in the download it took several hours to remove them.

    Summary

    My personal opinion is to skip this download as you don't know what you are getting with it. There are no choices in selecting what to download so you get the whole package-----good and the bad.

    "VERY basic. Very basic!"

    May 18, 2010  |   By michiganman5

    Version: Free Port Scanner 2.7

    Pros

    shows all ports and their status. Fairly easy to use.

    Cons

    Can't stop the scan once started (has button for it, but it doesn't work during scan).

    Pretty slow going through all ports, even on local machine takes a couple minutes.

    NOTHING TO IT! just scans ports, no configurability.

    Summary

    sort of does what it says, except slow, some things don't work (stop button), but for free, what do you expect.

    Never seen advertisements right on the main page like that. Guess that's how they pay for it.
