medicine distribution after attackers gained access through a phishing email and exploited unpatched vulnerabilities within the network.
These incidents highlight a recurring pattern. The problem is rarely a single missing control. Instead, it is the accumulation of small weaknesses like incomplete visibility into assets and vulnerabilities, weak access control, insufficient segmentation between IT and operational systems or slow remediation processes. In many cases, organizations are forced into full shutdowns because they lack the ability to contain an incident once it is underway, or they lack the confidence that their security stack will do its job. This is why containment is the critical control, rather than detection alone.
Addressing these structural issues can significantly improve both cyber resilience and satisfy regulatory compliance.
Three changes that deliver the greatest impact
While every manufacturing environment is different, organizations looking to strengthen their cybersecurity strategy often see the biggest improvements by focusing on three areas.
1. Start with asset visibility Every cybersecurity framework begins with the same fundamental question: what needs to be protected?
Yet many manufacturing organizations still struggle to maintain an accurate inventory of connected devices across their environment. Industrial controllers, sensors, remote access tools, engineering workstations, and thirdparty connections can easily fall outside traditional asset management processes and the interconnectivity and dependencies are rarely tracked.
This lack of visibility creates risk because either vulnerabilities cannot be identified
