Zenmap is a Windows program that offers users a graphical interface for Nmap, which is a powerful LAN scanning solution. Similar to NMapWin, there are instruments for exploring, documenting and analyzing various network activities. It is possible to generate comprehensive reports as well.

Environment analysis

The software includes several preconfigured scan profiles like Quick and Intense to accommodate different scenarios. Moreover, you can create and save custom presets to streamline recurring tasks.

Tools to manually define device parameters for a more tailored approach are provided, helping pinpoint vulnerabilities and focus on problematic areas. Users are able to specify:

Ports;
IP addresses;
Communication protocols and more.

Network mapping

Visual topology maps that show interconnected hosts and devices in a detailed graphical view are available. They are especially beneficial for identifying isolated structures, resolving potential bottlenecks and locating weak points within the infrastructure. This enables system administrators to optimize traffic delivery routes and reduce latency across the network.
