5 Best Software to Check Ports [Open Ports & Advanced Scanners]

ManageEngine OpUtils is a reliable network management tool that comes with a Port Scanner feature. This advanced feature makes scanning your network switch ports and the system’s TCP and UDP ports easier.

You can also specify a timeout value for the scan and choose to run a Basic or Advanced scan. The Advanced scan option will provide detailed information on open ports, including the service name and version.

This is extremely useful to identify potential security vulnerabilities by recognizing the open ports that attackers could use to gain access to sensitive information.

You can scan a single IP address or a range of IP addresses to see if they are open or closed. It also identifies the ports blocked by firewalls or other network devices, real assets to troubleshoot network connectivity issues.

OpUtils monitors your network devices, including servers, routers, printers, and switches, in real-time. The software offers threshold-based alerts and notifications that help determine and resolve issues before they escalate into critical problems.

With the Switch Port Mapper feature, the solution enables you to map the physical connectivity of your network devices, such as switches, routers, and servers. You can also identify the devices that are connected to each switch port and can help troubleshoot network issues related to them.

You also have a bandwidth monitoring feature for real-time usage monitoring across your network, allowing you to identify bandwidth-hogging applications or users and take corrective measures.
