OT security: operational technology
Where a compromise opens a valve rather than a file

What it is
Operational technology (OT) security protects the control systems that run physical processes (power grids, water treatment, pipelines, ports and industrial plants) where a cyber incident does not corrupt a spreadsheet but opens a valve. It is a discipline of its own, not IT security with different branding.
How it is employed
OT security is applied to the estate as it actually exists: assessment of ageing control systems never designed for hostile networks, segmentation between control and corporate environments, monitoring that understands industrial protocols, and response plans the plant operators themselves can execute, including when connectivity fails.
Why it matters now
Attacks on utilities, ports and industrial infrastructure across the region have moved from theory to precedent, and much of the installed OT base is decades old and documented, if at all, by the foreign vendors who built it. The consequences of compromise are measured in blackouts and closed ports, not lost files.
Procurement & integration
OT engagements begin with an estate assessment and a prioritised hardening roadmap, executed with the operators who run the systems and verified afterwards. Unstrat delivers assessment, hardening and continuous defence through one accountable team, with no foreign-government reporting line on what is found.

| Approach | IT security patterns misapplied to control systems | OT-native assessment, segmentation and monitoring |
| Disclosure | Findings may be reportable to a foreign government | What is found in your infrastructure stays accountable to you |
| Political conditions | Disclosure rules, re-export restrictions and upgrade approvals held by a foreign government | Independent, non-aligned origin, accountable to the buyer's flag |
| Accountability | Multiple contractors and a foreign prime's release schedule | One accountable team from first briefing through delivery and in-region sustainment |

What is OT security?
Operational technology security protects the control systems that run physical processes, power grids, water treatment, pipelines, ports and industrial plants, where a cyber incident does not corrupt a spreadsheet but opens a valve. It is a discipline of its own, not IT security with different branding.
How is OT security different from IT security?
The consequences differ. In OT the compromise is measured in blackouts and closed ports, not lost files, so applying IT security patterns to control systems misses the point. OT security uses OT-native assessment, segmentation and monitoring built for the estate as it actually exists.
OT security for critical national infrastructure
OT security is applied to ageing control systems never designed for hostile networks: segmentation between control and corporate environments, monitoring that understands industrial protocols, and response plans the plant operators can execute, including when connectivity fails.
Which products deliver an OT security programme?
OT security is a reference that draws on infrastructure hardening, off-grid cybersecurity and maritime cybersecurity. Hardening reduces the attack surface, off-grid architectures protect the disconnected parts, and maritime cyber extends the discipline to ports and vessels, all through one accountable channel.
OT monitoring that understands industrial protocols
That protocol awareness is the distinction from generic IT tooling. OT security applies monitoring that understands industrial protocols and segments control from corporate networks, rather than misapplying office-network patterns to systems that move physical processes.
OT security with no foreign-government reporting line
Findings stay with you. Where a foreign-aligned route may make what is found reportable to a foreign government, our model keeps what is found in your infrastructure accountable to you, delivered by one team with no foreign-government reporting line.
How does OT security sit inside a critical-infrastructure programme?
It is the control-system layer of that programme. The critical-infrastructure resilience solution reduces and watches the cyber attack surface with hardening and defensive operations and keeps isolated systems protected with off-grid architectures, and OT security is the reference tying those to the physical control estate.
Our utilities and ports run ageing control systems built by foreign vendors. How does an OT security engagement start?
It begins with an estate assessment and a prioritised hardening roadmap, executed with the operators who run the systems and verified afterwards. Because the installed base is old and documented, if at all, by the foreign vendors who built it, the assessment maps what is really there before segmentation and monitoring are applied.
Our OT sites lose connectivity for long stretches. Can OT security still cover them?
Yes, because the reference includes off-grid architectures for exactly that. Response plans are written so the plant operators themselves can execute them, including when connectivity fails, and the disconnected parts of the estate are protected by architectures designed for air-gapped and intermittent operation.

How does OT security connect assessment, hardening and continuous defence into one programme?
OT engagements move from an estate assessment and prioritised roadmap into hardening and continuous defence, all through one accountable team. That means the same team that maps the control estate also reduces its exposure and watches it, rather than passing the work between separate contractors.
Why does OT security warrant a non-aligned supplier rather than a major-power provider?
Because the consequences of compromise are national, blackouts and closed ports, and because a major-power route may make findings reportable to a foreign government. A non-aligned route keeps what is found in your infrastructure accountable to you, with an origin accountable to your flag and one team from briefing through in-region sustainment.
Can one OT security programme span the grid, water, pipelines, ports and industrial plants?
That breadth is what the reference is for. OT security protects the control systems behind power grids, water treatment, pipelines, ports and industrial plants, drawing on hardening, off-grid and maritime cyber. Delivered through one accountable channel, a state can cover several control estates under a single line of accountability.

What evidence should we ask for before committing an OT security programme, if this page publishes no numbers?
Judge it on method rather than a metric, since no audited figures appear here. The commitments are OT-native assessment of the estate as it is, segmentation between control and corporate environments, protocol-aware monitoring, and response plans the operators can run, executed with your team and verified.
How do we test OT defences without disrupting a live plant?
Authorised offensive assessment includes adversary emulation against industrial control systems, and it is governed to protect the live service, with authorisation and rules of engagement agreed in writing at the top. The findings then drive the OT hardening and monitoring rather than sitting in a separate report.
Who holds the detailed picture of our control estate once an OT security programme runs?
You do. The distinction OT security draws is that a foreign-aligned route may make findings reportable abroad, whereas doing the assessment and hardening with your operators keeps what is found in your infrastructure accountable to you, under one accountable team.
