Port Discovery

Find a port that's open now but wasn't before.

Port discovery scans a host you own across the full TCP range and reports any port that has newly opened — an exposed database, admin panel or debug port. Only scan infrastructure you own or are authorized to test.

What it detects

  • Newly opened ports, by number
  • Ports outside the list you expect to be open

How you're alerted

  • “New Open Port Detected” fires on its own when a port newly opens.

Notifications go to any of 8 channels — see notifications.
