FAQS
What is a Port Scanner?
A port scanner probes a server or network to determine which network ports are open and listening for incoming connections.
Why are open ports dangerous?
Open ports themselves aren't dangerous, but the software listening on them might have vulnerabilities. Closing unused ports minimizes your attack surface.
What does "Filtered" mean?
"Filtered" means a firewall or network appliance is dropping the packets silently, so the scanner cannot determine if the port is actually open or closed.
Can I scan any IP?
Our tool is designed for system administrators to verify their own infrastructure. Scanning third-party networks without permission is strongly discouraged.
