The line stops long before the ransom is paid.
Ransomware that stops a production line stops revenue, and IT/OT convergence widens the attack surface every year. We frame downtime and IP loss as the operational risks they are, and build the controls that keep the line running.

Ransomware that stops a production line stops revenue — and IT/OT convergence widens the attack surface.

What the obligation actually requires of you.
- 01
Critical-infrastructure obligations (where applicable)
Manufacturers connected to critical supply chains may carry obligations under critical-infrastructure legislation — worth confirming before an incident forces the question.
- 02
Privacy Act 1988
Where the Privacy Act applies, employee, customer and supplier records need reasonable protection, even in a production-first business that rarely thinks of itself as holding personal data.
- 03
Operational-technology security
The convergence of IT and OT means a phishing email on an office laptop can end with a production line stopped — a risk with no dedicated regulator, but very real consequences on the factory floor.
controls to review
Use this sector-specific set of practical prompts to identify owners, evidence and the next control to verify.
A lateral-movement attempt toward the production network.
Illustrative scenario — In this example, A phishing email compromised a single office workstation. The attacker began probing the corporate network for a path toward the production-scheduling and SCADA-adjacent systems on the plant floor.
Example response — A suitable response is to isolate the office segment, preserve endpoint and network evidence, verify the IT/OT boundary and restore only after testing.
What to verify — Confirm the relevant control is configured, tested and evidenced for this scenario; record the owner, review date and any exception before treating the risk as addressed.
Control evidence to collect
Configuration, test evidence, an accountable owner and a review date for the controls described in this scenario.
Illustrative scenario only. It is not a client case study, endorsement, zero-loss claim or proof of a security outcome.
Run it yourself, then see the priorities.
Review each practical control, assign an owner, and get an educational action list before you request a prepared follow-up.
These are practical control prompts, not a legal compliance determination. Exact obligations vary by entity, asset, contract and jurisdiction.

The questions this vertical always asks.
We isolate what can't be patched — network segmentation and monitoring around legacy OT to reduce the paths from a corporate compromise toward the plant floor, then validate the boundary.
We assess and deploy around your production schedule. Changes that could affect the plant floor are planned with an agreed maintenance window and rollback path.
Both. The entry point is almost always IT — a phishing email, a compromised credential. The consequence is production downtime and, sometimes, safety risk. We close the path between the two.
