I'm on the lookout for a instrument that enables me to observe a number of IP addresses/domains for open ports. I would like the instrument to ship alerts through e-mail or different integrations when the standing of open ports modifications.
The concept is that I’ve shoppers who’ve firewalls, and I need to detect if the firewall is working and if somebody has modified the firewall settings, doubtlessly opening a port to the surface world. Ideally, the instrument needs to be open-source and self-hosted.
