Government & Data Centre Protection

Government buildings and data infrastructure represent two of the highest-value intelligence targets in any nation. A drone hovering silently at rooftop height above a government compound or a hyperscale data centre is not merely a nuisance — it is a collection platform capable of conducting signals intelligence (SIGINT), photographic reconnaissance of physical security configurations, and in adversarial scenarios, a delivery vehicle for electronic warfare payloads or physical devices. The convergence of drone miniaturisation, extended flight endurance, and sophisticated onboard sensors has fundamentally altered the threat calculus for facilities that were previously considered secure behind their perimeter fences.

Government Facilities: The Aerial Surveillance Gap

Traditional physical security for government buildings focuses on controlled access points, vehicle exclusion zones, and personnel vetting. These measures are effective against ground-level threats but offer no protection against aerial observation. A drone carrying a high-resolution optical sensor can orbit at 150 m altitude — well above the sight line of any ground-based guard — and systematically photograph entry points, security patrol patterns, vehicle movements, and the facial features of personnel entering and leaving the building.

More sophisticated platforms equipped with directional RF listening payloads can conduct passive interception of unencrypted or weakly encrypted communications from government offices, targeting laptop screens visible through upper-floor windows with laser-based eavesdropping devices, or mapping the electromagnetic signature of internal network infrastructure.

The threat is not confined to static government buildings. Legislative chambers, ministerial compounds, diplomatic missions, and military command facilities all share the same aerial vulnerability. The counter-drone radar requirement at these facilities is accordingly among the most stringent in any application domain.

Data Centres: The Physical Attack Surface

Data centres are widely understood as cyber targets, but their physical attack surface is less well discussed. A determined adversary with access to a small drone can:

• Deploy a rogue WiFi access point onto a rooftop air handler or cooling duct, creating an unauthorised wireless bridge into the facility’s internal network infrastructure
• Insert a hardware keylogger or network tap by lowering it on a monofilament line through a rooftop ventilation opening — a technique demonstrated in multiple penetration testing exercises
• Conduct thermal imaging reconnaissance of cooling system configurations to identify hot spots that reveal high-density compute locations — intelligence valuable for sabotage planning
• Deliver an incendiary or EMP payload targeting power distribution units or cooling equipment — a low-probability but catastrophic-consequence scenario for Tier III and Tier IV critical infrastructure

The financial and reputational consequences of a data centre outage caused by a physical drone-enabled attack are comparable to a major cyberattack, with the additional complications of physical damage remediation and potential regulatory sanctions under data protection legislation.

Telecommunications Hubs

Major telecommunications nodes — internet exchange points, 5G core facilities, submarine cable landing stations — are similarly exposed. These facilities often occupy non-descript industrial buildings with minimal visible security, making them attractive targets for adversaries who have identified them through open-source intelligence. A drone delivering a coordinated physical or electronic disruption payload to a major internet exchange could affect connectivity for millions of users across an entire national network.

Cyrentis CR Series Deployment for Government and Digital Infrastructure

Counter UAV Radar’s Cyrentis CR Series addresses the specific requirements of government and data infrastructure protection through several key capabilities:

Silent, passive operation: Cyrentis CR radars operate in receive-only mode for classification, with transmit power optimised to minimise detectable RF emissions that could themselves become an intelligence signal. This is critical in sensitive government environments where electromagnetic emission profiles are closely managed.

Covert installation options: CR-PX10 and CR-PX15 units can be installed in low-visual-signature configurations — flush-mounted on parapet walls, integrated into rooftop equipment racks, or concealed within architectural features — allowing protection of sensitive facilities without advertising their counter-drone capability to potential adversaries.

High-sensitivity micro-drone detection: Government-targeting espionage operations often utilise the smallest available platforms — sub-100 g fixed-wing gliders or nano-quad rotors — specifically to evade detection. The Cyrentis CR Series’ 0.01 m² minimum detectable RCS is among the most sensitive specifications available in commercially deployed systems.

SCIF and sensitive compartment compatibility: For facilities operating sensitive compartmented information facilities (SCIF) or equivalent classified areas, Cyrentis CR radars can be supplied in configurations that meet Faraday shielding and TEMPEST emission requirements for integration into classified security environments.

Model Selection and Quantified Coverage

Government and data-centre sites share a common geometry: urban rooftops, close-in threat distances, and an electromagnetically dense environment. The table below maps each deployment role to a Cyrentis CR model with its key figures:

Two worked examples for planning purposes:

• Single data centre campus: one CR-PX15C on the highest roof provides instant 360° coverage of the campus and its approach roads; CR-PX10B units on secondary buildings close the overhead gap above rooftop cooling plant and power infrastructure; a CR-FK02 at the main gate watches the fence line and vehicle approaches, adding the ground-level awareness that the air-surveillance layer does not provide.
• Distributed government district: CR-PX15C nodes on two anchor buildings establish persistent coverage of the district core, while one or two CR-PK13B turntable units are relocated between ministry rooftops to surge protection around visiting delegations or public events. CR-FK02 units at each compound entrance cover pedestrian and vehicle movement alongside low-altitude air traffic.

Because the urban environment is dense with birdlife and legitimate helicopter traffic, the onboard micro-Doppler and trajectory classification performs the first filtering pass, and only confirmed drone-class tracks raise operator alerts.

Reference Deployment: Government District Pilot

In a capital-city government district — a cluster of ministerial buildings around a shared data facility — the protective-security directorate ran a pilot built around two fixed four-faced radar nodes on the tallest rooftops and a Ku-band turntable unit that moved between buildings on a published rotation. A Ku-band FMCW unit at the main vehicle entrance added ground-movement tracking to the air picture, so a single operating picture covered a drone at 150 m altitude and a loitering vehicle at the perimeter with equal continuity.

The operating concept was deliberately quiet: no visible perimeter changes and no publicised capability, consistent with the district’s low-signature posture. Radar tracks feed the existing security management platform as a new alert layer, and a confirmed drone track cues the nearest PTZ camera and notifies the duty officer. When a small drone crossed the district boundary during the evaluation window, the duty log captured the full track — launch direction, loiter point, and egress route — and the response focused on locating the operator on the ground rather than the aircraft in the air. The directorate’s internal review emphasised exactly that shift: the district moved from reliance on chance visual sightings to a documented, time-stamped detection record covering every low-altitude contact over the compound.

Integration with Existing Government Security Infrastructure

Government facilities typically operate sophisticated integrated security systems. Cyrentis CR radars connect to these systems via standard open protocols (TCP/IP, REST API, ASTERIX), enabling radar tracks to appear as alert overlays on existing security management platforms without requiring system replacement. Access control, CCTV, and guard dispatch systems can receive automated drone alert triggers from the Cyrentis CR system, enabling a co-ordinated multi-layer response that is faster and more reliable than manual detection and reporting.

For facilities requiring the highest level of protection, Cyrentis CR radar tracks can be fed to authorised counter-drone effector systems — RF jamming, GPS spoofing, or kinetic interdiction devices — in jurisdictions where these measures are legally permitted under counter-drone authority frameworks.

The Cyrentis CR Series represents a critical upgrade layer for any government or digital infrastructure facility seeking to close the airspace gap that conventional perimeter security has left unaddressed.

After radar establishes a track, an EO/IR sensor can provide visual or thermal confirmation and preserve image evidence for operators.
