NexusMap

NexusMap is a web-based network scanner and topology mapper built in Go. It provides an integrated interface for running Nmap scans, managing results, visualizing network topology, and exporting data — all from a single self-contained binary.

Features

  • Scan Management — create, run, monitor, and review Nmap scans with real-time progress via SSE
  • 40+ Built-in Profiles — organized by category: discovery, TCP/UDP scanning, evasion, timing, comprehensive
  • Custom Nmap Args — with safety validation (shell injection and dangerous flags blocked)
  • Consolidated View — merge results from multiple scans with deduplication, advanced filtering, labeling, notes, per-port history, and revert
  • Live Host Discovery — ARP + ICMP discovery with status tracking, ping checks, bulk operations
  • Topology Graph — interactive vis-network graph with subnet clustering, Maltego-style visual design, neighbor highlighting, BFS pathfinding, layout switching, export PNG, context menu
  • Real-time Streaming — scan output, port discoveries, and status updates via Server-Sent Events
  • Inline Editing — double-click to edit scan results, bulk edit, full change history with revert
  • Import/Export — Nmap XML, Gnmap, CSV, JSON, normal format, full DB merge
  • Scheduling — time-based and dependency-based scan scheduling
  • NSE Integration — browse and run Nmap Scripting Engine scripts
  • Authentication & Security — session cookies, bcrypt hashing, CSRF protection, rate limiting, input validation, CSP headers
  • Role-Based Access — admin and user roles
  • Dark Theme — modern dark UI with light theme option

Quick Start
