Critical cyber risks for manufacturing
Ransomware shutting down production lines and operational technology (OT) systems
Lack of IT/OT network segmentation allowing lateral movement from corporate to plant floor
Supply chain compromise through vendor portals and EDI integrations
Intellectual property theft targeting proprietary designs and trade secrets

Why manufacturing get denied
These are the most common reasons cyber insurance carriers decline or require remediation from manufacturing before binding coverage.
No MFA on corporate email, VPN, or ERP systems used across manufacturing operations
Zero network segmentation between IT corporate networks and OT/ICS environments
No endpoint detection and response (EDR) on workstations or servers — only basic antivirus
Missing business continuity and disaster recovery plan with tested failover for production systems

Frequently asked questions
Why is manufacturing the lowest-scoring industry for cyber insurance readiness?
Manufacturing has historically underinvested in cybersecurity because the industry prioritized operational uptime over IT security. Most manufacturers lack basic controls like MFA, EDR, and email authentication. The convergence of IT and OT networks without segmentation creates massive attack surfaces. Carriers view unsegmented manufacturing environments as near-certain ransomware targets, leading to the highest denial and remediation rates of any industry.
How does OT security affect cyber insurance for manufacturers?
Operational Technology (OT) systems — PLCs, SCADA, HMI, and ICS environments — are increasingly connected to corporate IT networks. Carriers now ask specifically about IT/OT segmentation, OT monitoring, and legacy system patching on applications. Manufacturers without documented OT security programs face higher premiums, lower coverage limits, and explicit exclusions for incidents originating from OT environments.
What should a manufacturer do first to become insurable?
Implement MFA on all corporate email and VPN access immediately — this is the minimum barrier to entry. Next, segment IT and OT networks with firewalls and monitoring. Third, deploy EDR on all Windows workstations and servers. These three controls address the top underwriting requirements and can be implemented within weeks, not months.
Does CMMC affect cyber insurance for manufacturers?
For manufacturers in the defense industrial base, CMMC compliance signals strong security posture to carriers. CMMC Level 2 maps closely to cyber insurance underwriting requirements including MFA, encryption, access controls, and incident response. Manufacturers with CMMC certification or active compliance programs typically receive better underwriting outcomes and lower premiums than those without any compliance framework alignment.
