How a Global Chemical Producer Strengthened OT Security, Met Compliance Demands, and Reduced Cyber Insurance Premiums by 57%

Industry Example: Chemical Manufacturing & Industrial Processing
Company Size: ~1,500 employees across 6 production sites
Annual Revenue: US $1.1 billion
Estimated Cyber Insurance Premium (Before): US $1,050,000/year
Estimated Cyber Insurance Premium (After): US $451,500/year
Savings: ~57% reduction through continuous validation and integrated cyber resilience

The Challenge

A global chemical manufacturer—producing industrial coatings, polymers, and specialty chemicals—faced mounting cybersecurity risk as its plants became more connected.
The company’s digital transformation initiatives had integrated IT systems with Operational Technology (OT), including process control networks, IoT-enabled sensors, and remote maintenance tools.

While modernization improved production efficiency, it also created serious new vulnerabilities:

  • Flat network architecture connecting IT and OT systems without segmentation

  • Legacy process controllers (PLCs and SCADA devices) running outdated firmware

  • Limited visibility into real-time cyber risks on the plant floor

  • Regulatory pressures from EPA, OSHA, and international supply chain partners requiring evidence of cybersecurity controls

  • Rising insurance premiums, as underwriters increasingly demanded validated OT/IT control data

Leadership recognized the need for a unified, verifiable cyber assurance strategy that could reduce risk exposure, satisfy compliance audits, and stabilize insurance costs.

The Solution

The company partnered with a cybersecurity provider (following the Antigen Security methodology) to deploy a comprehensive cyber assurance and control validation platform tailored to industrial manufacturing environments.

Key Components Implemented:

  • Continuous OT/IT Control Validation: Automated checks to ensure access controls, patching, endpoint protection, and network segmentation policies remained active and effective.

  • Real-Time Visibility into Process Networks: Monitoring for unauthorized communications between plant control systems, engineering workstations, and remote access connections.

  • Asset Discovery & Risk Scoring: Identification of all connected OT assets with live risk scoring to prioritize patching and segmentation.

  • Incident Readiness Playbooks: OT-specific response procedures for ransomware, insider misuse, and external supply chain compromise.

  • Insurer-Ready Reporting: Generation of automated cyber posture reports mapped to NIST CSF, ISA/IEC 62443, and ISO 27001 standards—designed for cyber insurance underwriting and compliance audits.

The Outcome

Within the first 60 days, the deployment uncovered multiple high-impact risks:

  • 14% of PLCs running unsupported firmware versions

  • An unprotected remote desktop gateway used by maintenance contractors

  • Weak password reuse across IT and OT environments

Remediation and validation were completed within weeks, followed by continuous monitoring to ensure long-term resilience.

Quantifiable Results:

  • Cyber control compliance increased from 63% to 97% across six facilities

  • 57% reduction in cyber insurance premiums due to insurer confidence in validated control data

  • $598,500 in annual premium savings

  • Enhanced coverage for OT incidents, business interruption, and third-party vendor breaches

  • No unplanned production downtime due to cyber events in the following 18 months

Operational and Strategic Benefits:

  • Simplified compliance audits for EPA, ISO 27001, and customer security reviews

  • Reduced cyber exposure across both IT and OT networks

  • Improved investor and board confidence through quarterly resilience reporting

  • Strengthened relationships with insurers and global supply chain partners

Why It Matters for the Chemical Manufacturing Industry

The chemical manufacturing sector faces unique cyber and operational risks:

  • Complex OT/IT convergence across plants

  • Legacy control systems that can’t easily be patched

  • High risk of ransomware disrupting production and safety systems

  • Increasing regulatory scrutiny and ESG requirements for cybersecurity governance

A single cyber incident can halt production, impact worker safety, and trigger environmental or compliance violations.

By implementing continuous control validation and insurer-ready reporting, chemical manufacturers can:

  • ✅ Reduce cyber insurance costs and expand coverage

  • ✅ Prevent costly production disruptions

  • ✅ Strengthen compliance with OT cybersecurity standards

  • ✅ Protect intellectual property, formulas, and production data

  • ✅ Build resilience across global manufacturing sites
