Scan Port

Scan Port is a lightweight Windows application that does exactly what its name says: it lets you scan a computer for open ports.
It’s pretty obvious that such a tool isn’t quite aimed at beginners, so the lack of a help section shouldn’t bother professional users too much.
What’s more, the intuitive program GUI makes everything quite a breeze, with all options grouped in a single window.
First of all, users are required to input the IP address of the target system, along with the port range they wish to scan. There are several filters for the results panel, which means that you are allowed to see only the closed or the open ones.
The results panel we were talking about displays brief information for every single port scan, while some statistics are displayed at the bottom of the window, including the number of open and closed ports.
There are no other settings to play with, which is actually very good news for those who don’t want to spend too much time with an unnecessary configuration screen.
Scan Port runs on low resources and doesn’t hamper system performance in any way. What’s more, it can be used on any Windows workstation, but special firewall rules to allow the app to access the network might be needed.
All things considered, Scan Port is one of the simplest ways to get port information on a specific computer. It doesn’t assault the user with unnecessary options and does exactly what it says with a single window that takes care of everything.
