How Defender EASM found open port 500 on my IP address, and using Nmap scanner I didn't find that the port is open?
I'm using defender currently on a 30 day trial, I'm wondering how Defender EASM managed to find open port 500. I've used Nmap scanner with different switches and tried to scan port 500 directly but I got no result that the port is open. Now I don't know if port is really open or not. Can you explain to me how Defender EASM was able to find an open port?
