There are a lot of tools out there for doing basic port scans on your edge devices. These tools are unnecessary if you access to a remote machine outside your network, but they come in real handy if you don’t. I saw this new tool on today and it’s a very nice simple tool that also packs in a GeoLocation feature that was more accurate than anything I’ve seen to date.

So if you find yourself in a situation where you need a remote port scanner, be sure to think… or don’t.
