Find open ports with our free online port scanner powered by Nmap. Scan up to 100 TCP or UDP ports of your choice, or the top 100 most common ports. Simply enter a target IP address, specify the protocol and ports to be scanned, and let our port scanner get to work. We’re fast—your results should be ready within seconds.

If you’d like us to handle your external port scans, consider purchasing a Syntinul subscription. Subscribers gain access to comprehensive periodic scans, alerts when changes to your attack surface are detected, tracking of changes, as well as integrations such as API and webhooks.
