Zenmap

Zenmap is the official graphical user interface (GUI) for the powerful and widely-used Nmap Security Scanner.

Designed to make Nmap more accessible for beginners while still offering advanced capabilities for experienced users, Zenmap for Windows brings a user-friendly interface to a tool often used in network security auditing and administration.



Ideal for IT professionals, penetration testers, and system administrators, it combines functionality with usability.

The program serves as a visual front-end for Nmap, one of the most trusted network scanning tools available. Nmap (Network Mapper) is used for network inventory, managing service upgrade schedules, and monitoring host or service uptime.

It simplifies the process by allowing users to construct and run Nmap commands using a GUI instead of the command line.

Features

Command Profiles: Save frequently used scan commands as profiles for easy access.

Searchable Scan Results: Compare scan results and search hosts across scans.

Topology Mapping: Visualize the network structure graphically.

Scan History Management: Track previous scans and compare changes.

Advanced Command Construction: Customize Nmap arguments using form fields.

Cross-Platform Support: Available for Windows, Linux, macOS, and others.

User Interface

The Zenmap interface is clean, functional, and straightforward. The main window is divided into several tabs including “Scan,” “Nmap Output,” “Ports/Hosts,” “Topology,” and “Host Details”.



Users can easily select a scan type, input a target IP or domain, and launch scans with a click. The graphical topology and filterable scan results add a layer of interactivity and depth not found in the CLI version of Nmap.

Installation and Setup

Installing this software on Windows is straightforward. Simply download the installer from the official website, run it, and follow the prompts.

The installer bundles Nmap and Zenmap together, ensuring you have both components. Administrative privileges are typically required.

How to Use

• Enter a target IP address or hostname.
• Select or create a scan profile (e.g., “Intense scan,” “Quick scan”).
• Click “Scan” to begin.

View results in various tabs to analyze the scan details, including open ports, services, OS detection, and network layout.
