Do you work on our DCS or safety instrumented system?▼
No. The DCS, safety instrumented system and controllers belong to your controls engineers and the vendors who support them, and changes there carry process safety implications. Our work stops at the boundary. We document and secure the connections between the business network and the control layer, set up the DMZ and jump host, monitor boundary traffic, control vendor remote access and protect the business systems around the plant. When a change affects the control side, we plan it with your controls team and let them make it.
Why is the historian connection such a concern?▼
Because it’s often the one sanctioned bridge between control and business networks, and it tends to grow over time. A historian that the business side can query directly, or one that also accepts connections from office PCs, becomes a path an attacker can use. The safer pattern is to replicate historian data to a server in a DMZ that business users query, with the control-side historian sending data outward only. We design that with your controls team and the historian vendor so production reporting keeps working.
How do you keep SDS information available during an outage?▼
OSHA’s Hazard Communication standard expects employees to be able to reach safety data sheets during their shift, and electronic access is fine only if it’s reliable. We host your SDS library on a backed-up system, and we also set up secondary access, such as a synced local copy on a dedicated device in the control room or a printed binder refreshed on a schedule. That way a ransomware event or internet outage doesn’t leave operators without hazard information when they need it.
Can you help with our insurer’s cybersecurity questionnaire?▼
Yes. Underwriters for manufacturers commonly ask about MFA, endpoint detection, backups, privileged access, network segmentation and remote access to control systems. We help you answer accurately and gather the evidence behind each answer, such as MFA reports, backup test logs and a boundary diagram. Where there are gaps, we prioritize the fixes that matter most to the underwriter. We won’t promise a premium change, since that’s the insurer’s decision, but accurate answers with evidence make renewals less painful.
We export some products. Does that affect our IT?▼
It can. Certain chemicals and related technology are listed on the Commerce Control List under the EAR, and technical data about them may need restricted access, including limits on who can see it. If your export compliance lead identifies controlled technology, we help restrict where those files are stored, tie access to authorization and log it. Classification and licensing decisions belong with your compliance team and counsel; we make sure the systems enforce what they decide.
What happens if ransomware hits the business network?▼
Endpoint detection and 24/7 SOC monitoring aim to catch it early and isolate infected machines automatically. Our engineers respond during business hours, and after hours for active incidents. Because the IT/OT boundary is narrow and monitored, the incident should stay on the business side, and your operations team can decide whether to run the process in a more isolated mode. We restore LIMS, ERP and document systems from immutable backups. Regulatory reporting and notification decisions stay with your leadership and counsel.
