Simple Port Tester is a networking and security tool for Windows. It allows you to check the status of your ports in regard to their accessibility from the outside world. Most of the time, you want to disable extra communication of your PC with the outer world, other than the main connection itself or router communication, so sometimes you just want ports to be closed and inaccessible.
Simple Port Tester allows you to input a port number and check whether it is reachable from the outside or not. It does so by sending a request to a website which then pings your computer and checks whether the port is open or not. The results are displayed almost instantly on the right side of the screen.
As of version 2, Simple Port Tester supports UDP and TCP ports - but if you analyze this application deeper than the nice-looking surface, it is easy to see that all it does is send requests to a website, which makes it rather useless altogether. You can just use your web browser for this. The results are accurate, but, honestly, Simple Port Tester is like a web browser that works with a single website. Also, it doesn't seem like it supports port range look-ups.
- It outputs accurate results
- It is nothing more than an application that uses a website to test ports.
- Lack of port-range scans
