Our Online Port Scanner provides a quick, lightweight way to check the status of common TCP ports on any public IP address or domain. Whether you are verifying that a web server (ports 80 and 443) is reachable, or making sure that sensitive services like SSH (port 22) or databases (port 3306) are safely hidden behind a firewall, this tool gives you instant visibility. It is designed for system administrators, ethical hackers, and developers who need a reliable external viewpoint of their network configuration. The scan runs efficiently, providing a clear report of open, closed, or filtered ports. Enhance your cybersecurity posture by performing routine checks with our free, browser-based port scanner.
