Observe industrial communications without touching the wire.
TorchBytes builds TorchScope, a protocol-agnostic diagnostics platform that captures, decodes, and explains serial and Ethernet traffic without injecting packets or relying on the cloud.
Passive by default. Offline always. Deterministic, auditable exports.

How TorchScope works
A deterministic pipeline that turns raw wire data into evidence-backed reports.
Capture
Record read-only traffic from RS-485 or Ethernet and save .capture + JSONL.
Decode
Protocol-aware decoding with framing, timing, and address visibility.
Transactions
Build request/response pairs with accurate timeout reporting.
Findings
CRC rates, jitter, poll gaps, duplicate ID suspicion, framing mismatch cues.
Report
Health report outputs in JSON, CSV, or HTML with evidence attached.
Timeline export
Replayable timeline exports for future UI ingestion and audits.
Trust posture
Designed to respect OT and cybersecurity boundaries. Observe, don’t interfere. Explain, don’t speculate.
Offline-only
No cloud dependency. Files stay on your laptop, lab, or appliance.
Read-only by default
Passive observation with no packet injection unless you explicitly enable it.
Deterministic replay
Replay captured sessions for stable, auditable findings.
Evidence-backed outputs
Reports include traceable evidence, not speculation.
Protocol and hardware roadmap
TorchScope is protocol-agnostic by design, starting with Modbus RTU and expanding to serial + Ethernet.
Modbus RTU (today)
Live capture, replay, transaction building, and health reporting.
5+ low-hanging protocols
Serial and Ethernet protocols prioritized by field demand.
TorchMonitor appliance
Always-on cabinet hardware for passive, offline diagnostics.
TorchProbe accessory
USB RS-485 tap/dongle for rapid capture sessions.
Protocol-agnostic core
Shared timeline, transaction engine, and export formats.
Future Ethernet analysis
Modbus TCP and related traffic with the same evidence pipeline.
