Portradar

Portradar is a freaking fast and stealthy port scanner. Hold my beer! I don't drink though :)

Subnet scan

It can scan for open ports across an entire subnet.

Specific port scan

It can scan for a specific open port across a subnet or host. This is very useful especially in pentesting. Gahdamn it, what's the fastest way to locate a Domain Controller in a network?

Specific port scan but with nmap

It can scan for a specific open port but instead utilize nmap for service and version enumeration.

Scanning a DC for open ports

I heard this took less than 25 seconds to complete 👀
