Operational Technology Services. Are You Checking the Grade?

I get asked about OT a lot. Usually by someone who's just been nodding along in meetings for six months and has decided it's finally time to find out what that term means. The term gets thrown around constantly in mining and energy. Rarely does anyone stop to explain it in a way that actually helps the person responsible for managing the risk around it. So here's that conversation. 

Your operation is running. The mine is producing. From where you're sitting, the technology is doing its job. But running isn't the same as managed. And in my experience, nobody's taken a core sample of their Operational Technology Services environment to find out what's down there. 

What Are Operational Technology Services and What Do They Actually Cover? 

Operational Technology services cover the management, monitoring, and security of the industrial systems that physically run your operation. They are distinct from IT services and require a different approach. 

Here's the simplest way I've found to explain it. Your IT environment carries information. Your OT environment also carries commands. IT keeps the business running, but OT keeps the operation running. SCADA systems, industrial controls, remote monitoring, safety instrumentation. The list is longer than most people expect when they first drill into it. 

What Is the Difference Between IT Services and Operational Technology Services? 

IT services manage information systems. OT services manage the physical systems running your operation. The distinction matters because a failure in each carries a completely different set of consequences. 

I hear this one a lot. "We've got managed IT sorted, so OT should be covered." And yeah, the IT side is probably being looked after. But that's usually not where the grade problem is. 

IT goes down, the business feels it. OT goes down, the operation stops.  

Pressure systems, safety instrumentation, processing controls. A failure there isn't measured in downtime. It's measured in production loss, safety incidents, and regulatory investigations.

Most industrial cyber incidents don't start in OT. They start in IT and move laterally because the boundary between them isn't managed. The ore body and the office block share more infrastructure than anyone realised.  

What Is OT Cyber Security and Why Does It Matter? 

OT cyber security is the discipline of protecting industrial control systems from cyber threats. It's different from standard IT cyber security because the systems involved were never designed to be defended the same way. 

Your IT environment gets patched and monitored. Your OT environment most likely doesn't get the same attention. A lot of industrial control systems are running on operating systems that haven't been supported for years. Some can't be patched without taking the process offline. Others have never been assessed at all.  

The Australian Signals Directorate has been clear that critical infrastructure OT environments are high-value targets. A cyber incident in OT doesn't just lock files. It stops production, triggers safety systems, and, depending on your SOCI Act classification, creates mandatory reporting obligations within hours. 

yesIT's OT security services are built around this specific challenge. 

How Do You Know If Your Business Has Adequate Operational Technology Services in Place? 

If you've never formally assayed your OT environment, you probably don't know what you've got. 

The conversation I have most often goes like this. Operations are running fine. Nothing dramatic has gone wrong. So the assumption is that OT is being managed adequately. That assumption is almost always wrong, and it's wrong in a specific way. The yield looks fine from the surface. But nobody's drilled into whether the systems underneath are actually monitored, maintained, and secured. 

Continuity and coverage feel identical from the inside. Until they don't. 

What Are the Signs a Business Is Carrying Unmanaged Operational Technology Risk? 

Unmanaged OT risk rarely announces itself. Like low-grade ore, it looks fine until someone actually samples it. 

A few things I find consistently when I start asking questions: 

• No formal OT asset inventory, especially across multi-site operations where assets have been added over years without a central register. 
• IT and OT managed by separate teams with no shared governance. Each assumes the other has the boundary covered. Neither does. 
• OT maintenance is reactive. Things get attention when they break, not on a schedule. 
• Nobody can clearly answer, ‘What would happen if this specific system went offline for 24 hours?’ A guess is not a documented response. 

What an OT asset inventory usually turns up 

Picture a regional energy business with remote monitoring across several unmanned sites. Their IT asset register is solid. Their OT equivalent is a three-year-old spreadsheet and what one operations engineer keeps in his head. Two remote site installations aren't on any list. Never recorded, never patched, nobody monitoring them. Under the SOCI Act, the business is still responsible for them.  

An afternoon of structured assessment changes that picture entirely. 

Operational Technology Services Frequently Asked Questions 

How Do Operational Technology Services Apply to Mining and Energy Businesses Specifically? 

In mining and energy, OT services cover the systems that run the operation itself. That's a different proposition from OT in most other contexts. 

In mining, OT is the SCADA systems, the remote monitoring across multiple sites, the safety instrumentation, the communications infrastructure. In energy, the same systems manage generation, distribution, and grid stability. A failure in either sector isn't measured in IT downtime. It's measured in production loss and safety exposure. High tonnage means nothing if the grade isn't there. 

How Do Compliance Obligations Like the SOCI Act Affect OT Services for Resource Businesses? 

The Security of Critical Infrastructure Act creates specific obligations for asset owners in sectors including resources and energy. OT services are a direct input to meeting them. 

The SOCI Act isn't coming for your IT team. It's coming for the people responsible for the systems that could cause real harm. In mining and energy, that's OT. The Act requires an asset register, a risk management programme, and cyber incident reporting within defined timeframes. If you haven't drilled into your OT environment, you can't meet those obligations. You don't know what you've got. 

When Should a Mining or Energy CFO Prioritise OT Services Over Standard IT Services? 

When the systems carrying your greatest operational and financial risk aren't covered by your current IT arrangement, that's the answer. 

The IT budget conversation usually centres on the corporate environment. Devices, connectivity, business applications, cyber security for the office.  

Fair enough.  

But the systems that determine whether the operation runs or stops, whether a safety event occurs, whether your SOCI Act obligations are met. Those sit in OT. Map what your current IT services cover against your OT environment. The yield gap is usually visible within an afternoon. 

Summary 

High tonnage doesn't mean high grade. An operation running flat out can look productive and still be carrying risk nobody's measured. OT is the part of your technology environment that determines whether the operation actually runs, and it's the part that gets the least scrutiny.
