NmapView

Stop staring at raw XML. Get instant, interactive insights.

NmapView transforms flat Nmap XML into a single, portable, interactive HTML dashboard for analysis and triage.

No backend, no database, and no reporting pipeline required. Open it locally amd review hosts, open services, service variants, and visualizations in one file. Share it, export from it, or archive it.

Quick Start

Render any existing Nmap XML file in seconds using xsltproc (pre-installed on most Linux/macOS systems):

# 1. Download the latest stylesheet
curl -fsSL -o NmapView.xsl https://github.com/dreizehnutters/NmapView/releases/latest/download/NmapView.xsl

# 2. Transform your scan
xsltproc -o report.html NmapView.xsl scan.xml

Open the generated HTML file in your browser.

Why Try It

• Turn raw XML into a report you can read and share without extra tooling
• Review hosts, open services, service variants, and host details in one place
• Search, sort, highlight, and export data to find "low-hanging fruit"
• Visualize technical scan data into insightful plots
• Keep the result as one portable HTML file

Core Features

• Single-file interactive HTML output
• Searchable, sortable tables
• Export to CSV, Excel, and JSON
• Global keyword highlighting
• Portable output you can share or archive

Report Sections

• Host Overview: Triage hosts by IP, hostname, vendor, OS guess, open TCP/UDP port counts or service rarity.
• Open Services: Review exposed services across hosts with versions, extra info, clickable CPEs, and Vulners-linked context.
• Service Summary: Group service and NSE output by service, port, product, and version so repeated software, web stacks, and unusual variants stand out across hosts.
• Host Details: Drill into each host scanned ports and corresponding complete script output

Visualizations

• Open Ports Per Host: Compare exposure across systems at a glance.
• Operating System Distribution: See which OS families dominate the environment and where platform diversity or concentration stands out.
• Service Distribution Across Hosts: See which services are most widespread and which appear on only a few hosts.
• Host-Service Relationships: See which services are shared across hosts and which are isolated.
• Host-Port Matrix: See which ports appear on which hosts and spot unusual exposure patterns.
• Service-Port Heatmap: Confirm expected port usage and spot unusual service-to-port combinations.

Requirements

• xsltproc to transform XML into HTML

No Python, Node, or backend required.

Typical Use Cases

• Internal network assessments
• External attack surface reviews
• Pentest evidence packaging
• Asset and service inventory review
• Comparing repeated service exposure across hosts
• Sharing scan results with engineers, clients, or internal stakeholders
• Reviewing large scans without working through raw XML
