Our pre-configured open port scanner comes with an easy-to-use interface over Nmap’s complex command line parameters. The Full version of this TCP Port Scanner with Nmap lets you scan open ports with custom settings right away. Compared to using Nmap on your local machine, it’s much more effective to check all open ports from our cloud platform because the TCP Scanner on gives you the external perspective of your target that any attacker has. NOTE: If the difference between the start and the end port is more than 500 then in that case the scanning can take longer to finish and in some cases where the difference is far too high, the scanning might never complete, so it's recommended to keep the port range short.Our open port checker provides an easy and fast way to run an online Nmap scan with zero setup and maintenance. The recommended scan type is 'connect()', however other scan types can also be useful depending on the network of the target host, a 'SYN Stealth' scan type can also prove to be useful when there's a firewall blocking the ports.

To scan a host just enter the host name or the IP address in the box above and give a range of ports to scan, if the host has firewall enabled then you can try a different type of scan in the advance mode. The service can also detect uptime of a host if the host is running one of the known Operating Systems which the scanner can analyze to guess uptime. Port scanner tool can be used to identify available services running on a server, it uses raw IP packets to find out what ports are open on a server or what Operating System is running or to check if a server has firewall enabled etc.
