OT Security Consultants

Harpoon Consulting deliver specialist Operational Technology (OT) security for UK manufacturers and critical infrastructure operators

The Reality of OT Security

OT environments are the backbone of modern industrial systems. And as they become increasingly connected to IT networks and external partners, they also become exposed to new and evolving cyber risks. OT security is no longer optional — it is essential.

The global financial risk from OT cyber incidents is now projected to exceed $329 billion

Cyber incidents in OT environments have doubled in the past three years

Nearly one third of organisations report six or more intrusions every year

OT Security Specialists

OT environments are not IT networks. They are safety-critical, complex systems built on decades of legacy equipment, proprietary protocols, and operational constraints. Securing them requires more than technical controls — it requires expertise in:

aligning security with operational continuity

engaging and upskilling the people who run the systems

designing processes that make improvements sustainable

OT Security Made Simple and Sustainable

At Harpoon, we balance people, process, and technology, to deliver OT security programmes that don’t just tick boxes — they protect operations, strengthen compliance, and build resilience that lasts. Our approach is built on a simple principle: OT security should be fast, sustainable, and simplified.

Fast

We focus on outcomes, not endless consulting cycles. Our lifecycle framework (Diagnose → Design → Build → Operate) gets you from risk to resilience quickly and efficiently.

Sustainable

We build on more than technology. Governance, training, and cultural adoption are baked in, ensuring changes last long after the project closes.

Simplified

We cut through jargon, complexity, and over-engineering to deliver solutions your teams can actually adopt and run with.

OT Security Services

Broken into four areas of focus, our end-to-end OT security offering empowers manufacturers, utilities, and critical infrastructure operators to embed cyber resilience across the full lifecycle of their operations.
