OT Ransomware and Manufacturing Continuity

Plant downtime costs more than IT outages. Segment OT, freeze unsafe remote paths, and plan manual fallback for critical lines.

Manufacturers face ransomware that stops lines, spoils inventory, and triggers contractual penalties. Flat networks between office IT and operational technology turn a desk-side compromise into a plant event.

Protect production, not only servers

Segment OT from IT, restrict remote vendor access, inventory controllers and HMIs, and maintain offline procedures for safe shutdown and restart. Patch windows must respect production calendars without pretending unpatched PLCs are fine forever.

Continuity exercises should include operations managers, not only cybersecurity staff.

Javan Informatics Group helps organizations turn these priorities into governed, operable programs—not one-off projects.
