Critical National Infrastructure

Unseen risks. Uninterrupted operations. Verified protection.

Protect essential infrastructure without disruption. Enable early threat detection, fast assessment, and uninterrupted operation across even the most remote or unmanned sites.

Security Without Disruption

Invisible Threats, Visible Risk

Most infrastructure runs silently, and so do the threats targeting it. One missed alert can trigger cascading failures.

No On-Site Dependence

When no one is present to respond, our solutions maintain 24/7 oversight with no operator needed on location.

Uninterrupted Operations

Protects the flow of essential services without slowing down site processes or adding manual overhead.

Built for the Background

Works in tandem with daily operations, ensuring security stays effective but unobtrusive.

Fewer False Alarms

Multi-sensor fusion and AI filtering reduce noise, allowing teams to focus only on verified alerts.

Built For Harsh and Remote Environments

Autonomous in Remote Sites

Operates without local infrastructure, ideal for substations, offshore platforms, and transport corridors.

Adaptable Across Terrains

Supports varied site types and layouts with modular components and scalable design.

Integrated with Existing Systems

Connects into current control rooms, sensor platforms, and incident workflows.

Resilient in Tough Conditions

Withstands weather, environmental interference, and connectivity challenges.

Threshold-Based Escalation

All alerts include context and are prioritised based on your operational risk model.

Intelligent Infrastructure Defence:
Oversight, Autonomy, Action

Critical infrastructure demands protection that works in silence, without operators on site or tolerance for false alarms.

Maintain Persistent Oversight

Delivers continuous multi-sensor coverage across airspace, ground perimeters, and remote assets.

Operate Without On-Site Staff

Runs autonomously in unmanned environments, with no dependency on local infrastructure.

Filter Out False Alarms

AI fusion reduces noise from weather, wildlife, and environmental interference.

Deliver Decision-Ready Alerts

Each alert includes supporting context, evidence, and escalation paths tailored to your protocols.

Adapt to Risk and Workflow Changes

Our solutions evolve with your threat landscape, operational model, and regulatory environment.

Beyond Drone Detection Systems: Verifying Airspace Matters

In this article, we explore why detecting drones isn’t enough and why airspace verification is critical for safety, compliance, and confident decision-making at high-risk sites.

Victor Chavez CBE Appointed as Chair

OSL has appointed Victor Chavez CBE as Chair, following a year of service as a Non-Executive Director. His appointment reinforces OSL's strategic focus on delivering advanced air and ground protection for fixed-site deployments in homeland defence and national security environments.

CUAS Myths Debunked: What Most Buyers Still Get Wrong About Drone Defence

At critical sites, safety hinges on more than just technology. It demands a clear and shared understanding of the threat landscape. Misconceptions around counter-uncrewed aerial systems (CUAS) don’t just risk wasting budget. They can lead to flawed procurement, ineffective integration, delayed responses, and, ultimately, operational vulnerability.
