The best of this software is that it has been very easy to learn and understand with its friendly interface. It also helps to detect vulnerabilities in real time without having to download or install any applications. I don't have anything bad to say about this tool. There's nothing much I can recommend because everything works just fine. In fact, we are using this online port scanner to check out if our servers are secure or not. This software has helped us greatly in finding potential attacks against our network which would otherwise be undetectable by other tools since they do not work offline.
