Automotive OT Security
OT cybersecurity for automotive and Tier-1 manufacturing — protecting robotic lines, welding cells, and just-in-time production where minutes of downtime cascade across the supply chain.
Automotive and Tier-1 plants run some of the most automated lines in industry: robotic cells, welding and stamping, and industrial networks where a few minutes of stoppage cascade through a just-in-time supply chain. The same density of PLCs, drives, and OEM remote access that makes the line fast makes it exposed.
Hillstrong secures automotive OT the way the plant runs it — availability first. We baseline each line, segment robotic and controls networks, rank risk by line criticality and JIT exposure, and monitor the IT/OT boundary passively so detection never threatens uptime.
Resilion tracks execution across every plant and platform, so controls stay current as models change and lines retool — and cyber governance aligns with the IATF quality discipline your operation already runs.
Frequently asked questions
- What are the biggest OT cyber risks in automotive manufacturing?
- Highly automated robotic and welding lines running on PLCs and industrial networks, just-in-time production where a short stoppage cascades to downstream plants, and dense OEM/integrator remote access — all of which make availability and boundary control the priority.
- How does Hillstrong secure automotive plants?
- We baseline each line, segment robotic and controls networks, rank risk by line criticality and JIT exposure, and stand up passive monitoring — then track execution across plants in Resilion so controls hold as models and tooling change.
