Port Scanner

The Port Scanner check common network ports on a target host to see if they are open or closed. This is essential for auditing server security and verifying if services like Web, FTP, or SSH are properly reachable.

Frequently Asked Questions

What is a Port?

A port is a virtual point where network connections start and end. They help identify specific processes or types of network services.

What does an "Open" port mean?

An open port means a service is actively listening for incoming connections on that port.

Is having open ports dangerous?

Ports that are not needed should be closed to reduce the attack surface. Only ports for necessary services (like 80 for HTTP) should remain open.

Which ports are scanned by default?

By default, we scan common ports like 21 (FTP), 22 (SSH), 25 (SMTP), 80 (HTTP), 443 (HTTPS), and database ports.

Can I scan custom ports?

Yes, you can enter a comma-separated list of specific ports you want to check in the input field.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout.
