When you work in manufacturing, you expect pressure. Tight deadlines, complex supply chains, and the constant drive for innovation. But nothing quite prepares you for the moment a potential nation state breach occurs on your environment.
That’s exactly what happened to one of our clients – a semiconductor manufacturer supplying critical components to global markets. The breach didn’t originate from their own systems. It came through a software patch deployed by a third-party provider, embedded in production tooling. It was subtle, sophisticated, and designed to go unnoticed.
The moment everything changed
We weren’t the incumbent provider at the time. But when the client’s internal team spotted unusual behaviour, they called us. At this point, our Network Detection and Response (NDR) service was deployed. We worked out of hours and outside of contract, because when production lines are at risk, there’s absolutely no time to wait.
“We worked out of hours and contract, picking up the incident through our NDR service, which surfaces hidden threat actor communications across a company’s cloud, on-premise and operational technology estate.”
The client’s existing tools were limited to endpoint detection. That left threat signals invisible. But our NDR spans the full estate, surfacing hidden communications and enabling swift containment before any production impact.
Unfortunately, this isn’t an isolated case. According to our latest research, 82% of cyber risk owners in Manufacturing have experienced a cyber attack, and 76% of employees say they’ve personally been a victim at work.
Why NDR matters in manufacturing
Manufacturing environments are uniquely vulnerable. Legacy OT systems often can’t support active scanning or endpoint agents. That’s why passive monitoring is essential. Our NDR operates silently, without disrupting production, and is invisible to attackers. It gives us the ability to detect lateral movement, command-and-control activity, and behavioural anomalies.
In this case, anomaly detection was key. The threat actor had not yet deployed ransomware or exfiltrated data. But their presence was clear in the patterns, unusual authentication attempts, irregular data flows, and beaconing behaviour. Our UK-based SOC analysts, working 24/7, validated the threat and initiated containment protocols within minutes.
“With 44% of Manufacturing organisations now relying on outsourced SOC providers, up from 27% in 2023, it’s clear that many are recognising the need for specialist support to navigate legacy systems and complex estates.”
What we learned, and what others can take away
The breach was contained before it could cause a production outage. No data was lost. No ransom was paid. And the client’s reputation remained intact. But the real lesson here is not just about technology.
Cyber security in manufacturing is not a one-size-fits-all service. It requires a deep understanding of each client’s environment, priorities, and risk appetite. That’s why we build relationships that go beyond SLAs. We act as an extension of our clients’ teams, not just a vendor on the side-lines.
According to our latest research, fewer than half of organisations feel they have this kind of relationship with their provider. Yet over 40% say it’s exactly what they want. And with over 70% of firms now rating cyber security as a board-level priority, the need for clarity, precision, and control has never been greater.
Final thoughts
This potential nation state breach could have ended very differently. But with the right visibility, the right people, and the right response, we helped a critical manufacturer stay online, stay secure, and stay trusted.
If you’re in manufacturing and wondering whether your current defences are enough, ask yourself: would your SOC spot a potential nation-state actor before it’s too late?
