OT continuous monitoring & threat intelligence
The on-board OT network is usually a black box — listen-only, light it up, and catch anomalies a step earlier.
- 0Packets injected
- Collected via a mirror port / TAP bypass, sending no packets into the OT network — 'listen-only' is a precondition of deployment.
- TAPBypass isolation
- A mirror port or TAP reads only a copy of the traffic, physically bypass-isolated from production systems — no interference with navigation or the engine room.
- E26Identify & Detect, landed
- Turning E26's Identify / Detect functions from a one-off document into a continuously running capability.
What it is
Passive visibility and continuous monitoring of the ship's operational-technology (OT/ICS) network: collecting traffic listen-only via a mirror port/TAP, identifying devices, building an asset inventory, and alerting on communication that deviates from baseline — never injecting packets into the OT network or disturbing navigation and engine-room systems. 'Threat intelligence' means collecting maritime-specific threat data (GNSS jamming/spoofing, ransomware activity, VSAT/satcom vulnerabilities, equipment-OEM supply-chain risk) and issuing targeted alerts.
Who it's for
Owners and operators who want continuous on-board industrial-network visibility and early anomaly detection, yet worry that the monitoring itself could affect navigational safety.
How we do it
We tap the OT segment, never touch it — a mirror port / TAP feeds traffic into a listen-only passive monitor, then an intermittent narrowband ship-shore link returns alarm metadata to a shore-based M-SOC, with no packets injected into OT and no interference with navigation.
Listen-only — never interferes with navigation
Monitoring coverage: how each layer works and what you get
| Layer | How it works (passive throughout) | What you get |
|---|---|---|
| Asset identification | Devices and protocols are fingerprinted passively from mirrored traffic; no active scanning | A continuously updated OT asset inventory (type / vendor / firmware / communication relationships) |
| Anomaly detection | A normal communication baseline is learned; behaviour deviating from it raises an alert | Anomaly / intrusion-detection alerts with context |
| Threat intelligence | Tracking maritime-targeted threats: GNSS jamming/spoofing, ransomware, VSAT vulnerabilities, equipment-OEM supply chain | Targeted alerts and threat briefings |
| Ship-shore relay | The intermittent narrowband link carries only alert metadata; raw traffic stays on board | A shore-side view of alerts and logs |
※ The monitoring node injects no packets into the OT network — 'listen-only' is a precondition of deployment, not an option.
What we do / deliverables
- Passive OT asset inventory (type/vendor/model/firmware/protocol/communication relationships, no active scanning)
- Network-topology and 'zones & conduits' mapping, IT/OT boundary and gateway inventory
- Anomaly / intrusion-detection alerts based on a normal baseline
- Ship-to-shore relay (under limited bandwidth, only alert metadata/logs are sent back)
- Maritime-focused threat-intelligence briefings and targeted alerts
Why choose us
Listen-only, never touching navigational safety — passive monitoring fits the reality of ships' safety-first priority and fragile legacy systems.
Landing E26's 'Identify/Detect' functions — turning abstract compliance requirements into a continuously running capability rather than a one-off document.
How the engagement runs
Deployment assessment
Confirm mirror-port / TAP feasibility, the current network segmentation and ship-shore bandwidth constraints.
Bypass connection
Install the collection point in a safe state, without touching the production network's configuration.
Baseline learning
Build a picture of normal communication and produce the first asset inventory and topology.
Continuous monitoring & review
Anomaly alerts and targeted intelligence run continuously; asset and topology changes are reviewed periodically.
