Why fences fail against FPV drones
CISA states that UAS can bypass traditional security measures such as perimeter fences, gates, and guards. FPV aircraft exploit that geometry: they do not badge in, climb the wire, or argue with the tower.
Why this matters
CISA bypass geometry, in plain language, for facility security leads. Buyers comparing OEMs, integrators, and in-house builds need clear language before procurement documents harden the wrong assumptions.
A complementary planning layer
Fences and gates still serve their ground-security purpose. An aerial approach calls for a separate assessment of visibility, exposed assets, sensor siting, and response responsibilities. An illustrative scenario is a planning tool, not evidence that an attack will occur.
Physical barriers also have limits
Passive netting can be considered around selected assets or routes. Geometry, supports, access, inspection, and environmental loading must be addressed in the design. Netting does not create detection or mitigation authority, and Veil does not claim validated interception performance.
Questions for a site assessment
- Which operations depend on exposed equipment?
- How will security assess and report an unexplained aircraft?
- What access and maintenance requirements constrain physical barriers?
