This article targets security directors, CISOs, event security leads and critical-infrastructure security officers. It offers a complete action framework aligning the French lessons learned with the international D-TIM-D methodology.
The D-TIM-D cycle
Detect — know that a drone is in the area of interest. Track — follow its trajectory in real time. Identify — qualify the drone and, if possible, the pilot (Remote ID). Mitigate — respond within the legal framework (internal alert, authorities, verification). Document — produce evidence.
The whole cycle must fit in the operational window (often under 10 minutes for a typical overflight).
Building the evidence chain
Evidence usable by prosecutors or insurers must accumulate: reliable timestamp, reconstructed trajectory, Remote ID if available, associated VMS clip, technical integrity (digital signature).
The signed PDF report generated by DECTYR RX-5 and DECTYR Hub covers those five points. It is consistent with the expectations of magistrates and insurers.
Target procedure (example)
- Sensor detection → alert raised to the control room / SOC.
- Verification through camera or agent in under 60 seconds.
- Decision: internal escalation (IT, leadership, law enforcement) per the criticality matrix.
- Notification of authorities (police, aviation authority, prefecture) if a likely infringement.
- Generation of the signed PDF report and archival.
- After-action review at D+1, matrix update.
Connection with other plans
Drone scenarios must feed your business-continuity exercises. Your plans should consider: VIP disruption, audiovisual blackout during a major event, exfiltration following a prolonged overflight of an industrial site.
Five pitfalls to avoid
- Treating drone detection as an IT-only topic.
- Underestimating law-enforcement mobilisation time (often longer than the overflight itself).
- Failing to train field teams to interpret a drone alert.
- Storing evidence without integrity control.
- Skipping the annual incident review.
FAQ
Target latency between detection and alert?
Under 2 seconds for sensor detection, under 30 seconds for escalation to the first on-call responder. Beyond that, the operational window collapses.
Do I need a dedicated control room for drones?
No, except on very large or highly exposed sites. Integration into the existing control room is generally the right path.
How do I work with law enforcement?
Set a protocol upfront: direct number, expected file template, named contact. The signed PDF report from the detector significantly speeds up case handling.
