Open your capture
Drag in a .pcap/.pcapng or resume an .ndap project to light up your topology instantly.
See your network's dataflows — instantly
FlowTruss builds the Network Dataflow Analyzer (NDA), which reads your PCAPs and renders a living map of nodes and flows. Highlight insecure protocols, focus on OT traffic, annotate diagrams, and export beautiful assets.
- Upload .pcap/.pcapng or .ndap projects
- Filter by protocol/ports, OT-only mode, and highlight insecure links
- Compare captures to spot added, removed, and changed flows
- Export PNG/SVG/PDF/CSV
Workflow
From packet capture to share-ready proof
A clean, guided path from first packet to the export your stakeholders need.
Local-first: packet data stays with you
Desktop + web builds
Exports: SVG / PNG / PDF / CSV
Filter/Investigate to the view you need
Toggle OT-only mode, spotlight insecure protocols, and apply search syntax to isolate the flows that matter.
Annotate what matters
Pin critical assets, drop callouts, and layer shapes or icons so findings stay attached to the flows they explain.
Export and share
Ship clean SVG, PNG, PDF, or CSV outputs-and keep the .ndap handy for future updates.
Product Highlights
Turn captures into confident decisions
NDA goes beyond static diagrams—it gives network and OT teams the clarity, context, and deliverables they need within minutes of loading a PCAP.
Instant topology clarity
NDA resolves complex environments into living maps that anyone can understand.
- Switch between force, grid, radial, or ranked layouts and pin key assets.
- Use focus mode to isolate critical segments before exporting.
Deep OT awareness
Highlight industrial protocols, insecure traffic, and vendor fingerprints with a click.
- Toggle OT-only views covering Modbus, DNP3, S7, CIP, OPC UA, and more.
- Surface risky flows automatically so remediation work starts sooner.
Evidence for every change
Compare captures or time windows to prove what changed and when.
- Color-coded adds, removals, and modifications eliminate guesswork.
- Annotate findings directly on the canvas for fast incident reports.
