Subaru of Indiana Automotive

Subaru of Indiana Automotive operates the sole Subaru manufacturing plant in the U.S., based in Lafayette, Indiana. Founded in 1987, the facility employs more than 6,500 people across production, engineering, and administrative roles. The plant produces the Ascent, Crosstrek, and Forester - including Subaru's first U.S.-built hybrid - as well as having manufactured the Legacy since 1989.

For security professionals, the threat model here is industrial. SIA runs a large-scale manufacturing environment with connected production systems, supply chain integrations spanning vendors and contractors, and operational technology networks that bridge physical assembly lines with enterprise IT. The plant was the first U.S. auto assembly facility to earn ISO 9001 certification, which signals a culture where process rigor and compliance are already embedded - useful context if you're inheriting or building out an OT security program.

The attack surface isn't theoretical: automotive manufacturing involves programmable logic controllers, SCADA systems, robotics, and hybrid production lines that demand air-gapped thinking even when the reality is anything but. With hybrid vehicle production scaling and thousands of employees plus external vendors touching the network, identity management, endpoint hardening, and supply chain security are concrete operational priorities rather than checkbox items.
