Drone threat detection · Baltic region

See the threat
before it arrives

Sentineller is a distributed sensor network that detects hostile drones — including military-grade threats that carry no identifying signals — and delivers real-time alerts to operators and authorities.

Architecture

Three detection layers.
One unified alert.

Sentineller nodes work in concentric rings around a protected site. Each layer adds depth — buying time, confirming identity, and enabling response before a threat reaches its target.

5–15 km
Early warning
Long-range passive detection
The outermost layer detects moving aerial objects at range — including threats that transmit no signals and carry no identification. Provides the critical minutes needed to activate response protocols.
In development
500 m – 2 km
Identification
RF anomaly & signal classification
The middle layer monitors the radio spectrum for unknown transmissions. Any unregistered signal source in the protected area triggers an alert — regardless of whether the drone carries Remote ID.
Operational
0 – 500 m
Confirmation
Visual, acoustic & identity confirmation
The innermost layer combines multiple sensing modalities to confirm threat type, trajectory, and intent. Registered aircraft are whitelisted; unknowns are escalated immediately.

Sensing methods

Multi-modal.
Continuously evolving.

Sentineller fuses multiple independent sensing modalities into a single threat picture. No single sensor is relied upon — confirmation requires agreement across methods.

📡
Passive Radar
Detects moving objects using ambient radio signals — no active transmission, no detectable footprint.
📻
RF Sensing
Monitors the radio spectrum for unknown or anomalous transmissions across multiple frequency bands.
📶
WiFi & Remote ID
Identifies registered drones and flags those operating without required identification — in real time.
🎥
Visual AI
AI-powered camera analysis classifies objects by type, size, and flight behaviour at the point of closest approach.
🔊
Acoustic AI
Acoustic fingerprinting identifies drone rotor signatures even when all other signals are absent.
✈️
ADS-B Monitoring
Long-range aircraft awareness provides full airspace context and separates commercial traffic from unknowns.
🧠
Sentineller Edge
On-premise AI inference for sovereign threat analysis. Data stays local — processed on dedicated edge servers, never in foreign clouds. Designed for defence and critical infrastructure partners.
Coming 2027

🔬
Sentineller's sensing capability is under active development. New detection methods are continuously integrated as the threat landscape evolves.

Applications

Where the stakes
are highest.

Sentineller is designed for environments where a drone incident is not an inconvenience — it is a national security event.

🏭
Industrial infrastructure
Refineries, chemical plants, and power generation facilities. A single drone strike on a critical node can cascade into a national crisis.
Ports & maritime
Coastal sensor chains monitor extended shorelines. AIS integration adds full maritime domain awareness alongside aerial detection.
💧
Water & energy utilities
Drone detection fused with infrastructure monitoring — perimeter breaches, pressure anomalies, and grid events in one unified system.
🛡️
Border & area protection
Multi-node chains extend early warning across wide corridors, providing 12–20 minutes of advance notice for fast-moving aerial threats.

Why now

The window
is open.

The drone threat has outpaced existing defences. The market for distributed detection is forming now — and first-movers will define the standard.

01
Proven prototype
Sentineller is operational today. Real detections, real alerts — not a concept, not a roadmap.
02
Baltic Drone Wall
The €362M Baltic Drone Wall initiative needs a distributed sensor layer. Sentineller is built to be that layer.
03
Posintra Turva-hanke
Accepted into Finland's national security innovation programme — opening direct paths to government and defence partners.
04
Investor interest
Early investor dialogue is underway. We are seeking partners who see the same urgency we do.

Get in touch

Let's build this
together.

We are looking for pilot sites, test partners, and investors who understand that the time to act on drone threats is now — not after the first incident.
