Nmap XML into
a clean report,
instantly

NmapView is an advanced Nmap XML report viewer that transforms flat Nmap scan results into a portable, interactive HTML report dashboard. Target hosts, open services, SSL certificates, NSE script output, and vulnerability references are automatically grouped into a clean nmap report format designed for rapid infrastructure investigation and security reporting.

Yes, 100%. When you drop an XML file into the browser version, your Nmap data is processed entirely client-side using JavaScript within your local browser sandbox. No network transmission occurs, meaning your network architecture data never leaves your local machine, making it completely safe for sensitive penetration testing environments.

The generated Nmap HTML report features built-in export actions. From the interactive data tables on the dashboard, you can instantly export filtered or global service inventories, open ports, and asset lists straight to Excel, CSV, or raw JSON data formats for reporting or further data manipulation.

Unlike traditional static XSL stylesheets or complex python-to-markdown reporting pipelines that require backend server setups, NmapView runs instantly using zero-dependency local utilities like xsltproc. It yields a single, double-clickable HTML dashboard packed with modern UI features like real-time global filtering, live text highlighting, and responsive layout data visualizations.

Absolutely. Because NmapView uses native XSLT 1.0, you can modify the underlying NmapView.xsl file to inject your own custom CSS styling, update brand colors, or change data columns to match your organization's internal vulnerability assessment and reporting standards.

Generate a report using xsltproc:

xsltproc -o report.html NmapView.xsl scan.xml

The generated report is a standalone HTML file that can be opened, shared or archived without additional infrastructure.

No. NmapView produces a single self-contained HTML report. No backend, API, database or container is required.

NmapView runs entirely in the browser and is ultimately constrained by the client's CPU, memory and browser implementation.

In practice, reports containing several hundred hosts remain highly usable on modern systems. Reports with around 500 hosts are typically handled comfortably while retaining filtering, exports and visualisations.

Very large enterprise scans may benefit from scoping the report to a subset of hosts before exporting data for further processing.

Yes. NmapView also provides a browser-based transformer that converts Nmap XML directly in your browser.

All processing happens client-side. Scan data is not uploaded to a server or transmitted over the network.

Host rarity scoring highlights systems whose service combinations are unusual compared to the rest of the scanned environment.

The score is based on principles from information theory and uses the concept of self-information. Services that appear on only a few hosts contribute more information than services found everywhere.

As a result, hosts running uncommon combinations of software naturally rise to the top of the inventory, helping surface outliers without manual sorting.

Yes. NmapView is commonly useful during internal assessments, external attack-surface reviews and penetration tests where rapid triage of large scan results is required.

The report can also be delivered alongside traditional findings as an interactive inventory of the scanned environment.

Yes. Generated reports are self-contained HTML files.

They can be attached to tickets, archived with assessment artefacts, shared with clients or reviewed offline without requiring access to the original scan environment.
