Passive physical barriers
Physical protection against drones using netting, mesh and cages, which sit outside the spectrum and operating-authority rules that constrain everything else in this segment.
This is the outlier in the segment and it is here deliberately. Every other aspect involves spectrum, authority or certification. A net involves a structure and a specification.
The commercial signals are unusual: the highest costs-per-click on the permitted side of the segment, and no specialist supplier visible anywhere in the search results. That combination is either an opportunity or a sign the buyers are elsewhere, which is exactly the kind of question a probe should answer rather than guess.
Why this is live now
- Passive barriers transmit nothing and intercept nothing, so the operating-authority and spectrum questions that govern detection and mitigation do not arise.
- Cost-per-click in this niche is the highest we measured on the permitted side of the segment, at $15.29 for netting and $18.10 for cages, against low volume.
- The search results for these terms are dominated by war reporting, an encyclopaedia entry and general industrial netting suppliers, with no specialist presence.
- Interest has been driven largely by battlefield use, which has not yet translated into a developed commercial offer.
Who this is for
- Correctional facilities managing contraband delivery
- Industrial and utility sites protecting specific assets
- Yards, compounds and equipment stores
- Operators wanting protection without a regulatory approval path
What we would do
Analysis and advisory work. We have no deployed installations in this segment and do not imply otherwise.
- Assessing whether a physical barrier addresses the actual exposure at a site, or only appears to
- Specification covering span, mesh dimension, mounting and load, and what the structure must carry
- Comparing a barrier against a detection approach on cost and on what each actually prevents
- Sourcing guidance, since most current suppliers are general netting manufacturers rather than specialists
FAQ
▸Does netting actually stop a drone?
Against a specific, bounded target such as a yard, an exercise area or a piece of equipment, a properly specified barrier physically prevents delivery or close approach, which no sensor does. It protects only what it covers, it does nothing about surveillance from above it, and battlefield footage shows barriers being defeated deliberately. It is a narrow measure that works well within its limits.
▸Is any approval needed?
Not of the kind the rest of this segment requires, because nothing is transmitted and no aircraft is interfered with. The constraints are ordinary ones, meaning structural loading, planning and permitting where applicable, and site safety.
▸Why is this on a list with certification and grant work?
Because it is the one part of the segment that is a physical product rather than a regulated capability, and we would rather find out whether that is what people actually want than assume it is not.
