Industrial organisations are facing escalating attacks on their operational technology — the systems that control physical processes and machinery. Unlike a typical IT breach, an OT incident can have real-world safety and production consequences.
Why it matters
OT was historically “air-gapped” and rarely updated, but growing connectivity has exposed these systems to the same internet threats as everything else — often without the security tooling that IT takes for granted.
The foundations are network segmentation between IT and OT, strict control over remote access to industrial systems, and monitoring tuned to OT environments. We design and manage these separations so connectivity doesn’t come at the cost of safety.
Why OT is harder to defend than IT
Operational technology was built for reliability and long service life, not for a world of constant internet threats. Controllers and machinery can run for a decade or more, often on software that can no longer be patched, and they frequently cannot be taken offline for maintenance without halting production. When these systems are connected to the corporate network — or reachable remotely by a supplier — they inherit every risk that IT faces, but without the security tooling IT takes for granted. An incident here is not just lost data; it can mean stopped lines, damaged equipment or genuine safety consequences.
A pragmatic approach
Start with an accurate inventory of what is actually connected, then put a firm boundary between IT and OT so office threats cannot reach the plant. Route any remote access to industrial systems through controlled, monitored gateways with multi-factor authentication, and apply monitoring tuned to OT rather than assuming standard IT tools will understand it. Where a system genuinely cannot be patched, wrap it in compensating controls instead. We design and manage these separations so that greater connectivity never comes at the expense of safety or uptime.
