Drone Guardian® Counter-UAS Protection

The problem: drone threats are harder to see, confirm and stop

Small drones can be difficult to detect, especially when they are low-flying, RF-silent, operating in groups or approaching from multiple directions.

For security teams, the challenge is not just detecting more activity. It is knowing which activity matters.

Many systems create more screens, more alerts and more workload. Drone Guardian is designed to do the opposite. It correlates multiple sensor inputs into a clearer operating picture, helping your team reduce nuisance alerts, confirm threats faster and respond with greater confidence.

Autonomous detection. Lower operator burden.

Drone Guardian EO/IR identification supporting counter-drone decision-making

Drone Guardian is designed to do more of the work before the operator needs to act.

It autonomously detects, tracks and identifies drone threats by correlating inputs from radar, RF, EO/IR, acoustic and other integrated sensors. The system helps confirm activity, reduce duplicate tracks and present a clearer operating picture.

That matters because counter-UAS operators are often distracted, multitasking or under pressure. Instead of adding more screens, alarms and manual checks, Drone Guardian helps reduce cognitive load, cut nuisance alerts and give teams more time to choose the right response.

Low Burden by Design

Drone Guardian is built for operators who cannot afford unnecessary noise.

Automated cueing, confirmation logic, camera control and configurable alerts help security teams focus on the threats that matter, rather than managing every sensor feed manually.

What is Drone Guardian?

Drone Guardian is an operationally proven counter-UAS system that autonomously detects, tracks and identifies drone threats.

It uses multi-sensor correlation to combine radar, RF, EO/IR, acoustic and other sensors into a unified operating picture, helping reduce false alarms, minimize operator workload and support faster, more confident response decisions.

Drone Guardian is sensor and effector agnostic, allowing organizations to integrate best-of-breed sensors, soft-kill options and hard-kill effectors around their site, threat environment and operational requirements.

Detect

Drone Guardian integrates multiple sensors to detect drone threats across complex environments.

Radar provides long-range, all-weather detection, including RF-silent and non-cooperative drones. RF detection supports passive awareness of the signal environment. EO/IR enables day and night confirmation. Acoustic sensing can support the detection of low-flying or difficult-to-detect threats.

Track

Drone Guardian correlates multiple detections into a single-track picture.

This helps reduce duplicate tracks and false alarms, giving operators a clearer view of what is happening across the protected area. It is designed to manage multiple simultaneous tracks, including swarms and complex drone incursions.

Identify

Drone Guardian supports automated cueing and camera control to help operators confirm and classify potential drone threats.

EO/IR imagery can support visual identification, classification and evidence capture, helping teams understand the nature of the threat and the most appropriate response.

Defeat

Once a threat has been detected, tracked and identified, Drone Guardian supports layered response options configured around the site, operating environment and customer requirement.

Soft-kill options can be configured for compliant electronic attack, where authorized. Hard-kill effectors, including VAMPIRE™, can also be integrated where appropriate. Drone Guardian’s open architecture is designed to support current and future effectors, helping organizations adapt their counter-UAS approach as threats evolve.

Why autonomous detection, tracking and identification matter

Drone Guardian - autonomous detection, tracking, and identification of UAS

In counter-UAS operations, response is only as good as the confidence behind it.

Drone Guardian is designed to autonomously detect, track and identify drone threats before presenting operators with a clear, correlated picture. By confirming activity across multiple sensors, the system helps reduce nuisance alerts, minimize duplicate tracks and give operators more time to choose the right response.

Where authorized and configured, Drone Guardian can also support automated cueing and response options, including soft-kill effectors or hard-kill systems such as VAMPIRE.

Point protection. Perimeter protection. Connected protection.

The Drone Guardian counter-UAS system is built around a simple idea: protection should scale from a single point of need to a connected defensive network.

A single SPIDER™ deployable counter-UAS tower provides agile, mobile, deployable counter-UAS protection. Multiple SPIDER systems can work together as a NEST™ networked counter-UAS system, extending coverage across a larger site, facility or perimeter. Where sensors, radars or existing defenses are already in place, WEB™ software-led integration layer connects them.

Together, SPIDER, NEST and WEB create a layered counter-UAS architecture that can autonomously detect, track and identify drone threats, then support the right response for the environment.

SPIDER: Agile, deployable counter-UAS protection
Best suited for: Temporary sites, event security, logistics hubs, and deployed locations.

A deployable tower or tripod-based configuration with integrated sensors, SPIDER is designed to autonomously detect, track and identify small drones at long range, before they are seen or heard.

Once a threat is identified, SPIDER supports response through integrated soft-kill options or hard-kill effectors such as VAMPIRE, depending on customer requirement, authorization and the operating environment.

Mobile enough to be relocated quickly, and with the potential to be mounted on robotic platforms, SPIDER provides flexible protection for temporary sites, event security, logistics hubs, deployed locations and other environments where counter-UAS coverage needs to adapt quickly.

In simple terms, SPIDER is the rapidly deployable hunter. It watches, confirms and enables action.

NEST: Networked protection for larger sites and perimeters
Best suited for: Critical infrastructure, airbases, prisons, ports, fuel depots, power plants, large facilities and perimeter protection.

For broader protection across a large base, facility, critical infrastructure site or perimeter, multiple SPIDER systems can be connected to create NEST.

NEST allows interconnected SPIDER systems to work in unison. They can share sensor data, coordinate tracking and support synchronised responses across a wider area, creating a collective shield around high-value locations.

This approach helps reduce coverage gaps and supports more resilient protection for sites where continuity, scale and confidence are essential.

NEST is suited to fixed and semi-permanent sites including airbases, military facilities, prisons, ports, fuel depots, power plants, critical infrastructure and other high-value locations.

In simple terms, NEST is the coordinated network. It connects multiple SPIDER systems to protect a larger area.

WEB: Software-led integration for existing sensors and defenses
Best suited for: Existing sensor estates, multi-vendor environments, phased upgrades, mature security sites and integrated security infrastructure.

Where sensors, radars or defensive systems are already in place, WEB provides the software integration layer that connects them.

WEB brings disparate capabilities into one cohesive counter-UAS network. It helps turn isolated systems into a unified operating picture, improving coordination, visibility and response without necessarily adding new hardware.

This makes WEB especially valuable for organisations with existing investments in sensors, radars or security infrastructure. It allows them to improve the effectiveness of what they already have, while creating a more scalable route for future upgrades.

In simple terms, WEB connects the existing estate. It creates a counter-UAS network without necessarily adding new hardware.
