The Hidden Cyber Risk Manufacturers Aren’t Budgeting For: Insurance Claim Denials

Cybersecurity investments are often justified by one goal: preventing attacks. But for many manufacturers, the more immediate financial risk may not be the cyberattack itself. It may be discovering that a cyber insurance claim is denied when the business needs it most.

As cyber threats increasingly target operational technology (OT) environments, insurers are paying closer attention to the security controls protecting production systems, industrial networks, and critical manufacturing processes. What was once primarily an IT issue has become a business continuity issue that reaches the factory floor, the boardroom, and the insurance renewal process.

Many organizations still view cyber insurance as a safety net. In reality, insurers are becoming active participants in risk management, requiring organizations to demonstrate specific security practices before issuing policies, renewing coverage, or approving claims.

For manufacturers operating aging production equipment, SCADA systems, programmable logic controllers (PLCs), and mixed IT/OT environments, understanding this shift is becoming essential.

Cyber Insurance Has Changed

A decade ago, obtaining cyber insurance was often a relatively straightforward process. Applications focused on general IT controls such as firewalls, antivirus software, and employee awareness training.

Today, insurers are asking much deeper questions.

Manufacturing has become one of the most targeted industries for ransomware and operational disruption attacks. As a result, underwriters increasingly evaluate:

• Multi-factor authentication (MFA)
• Network segmentation
• Backup and recovery testing
• Incident response planning
• Third-party vendor access controls
• Security monitoring capabilities
• OT security controls
• Asset visibility across IT and industrial systems

The reason is simple. Manufacturing cyber incidents frequently produce losses that extend far beyond data exposure. A ransomware attack that halts production for several days can lead to missed shipments, contractual penalties, supply chain disruptions, regulatory implications, and significant revenue loss.

Insurers recognize these risks and are adjusting expectations accordingly.

Why Operational Technology Is Receiving More Attention

For years, industrial control systems were largely isolated from traditional business networks. Today, most manufacturers rely on connected production environments that exchange data between machines, engineering systems, ERP platforms, cloud services, vendors, and remote support teams.

This increased connectivity creates efficiency, but it also expands the attack surface.

Operational technology includes systems such as:

• SCADA platforms
• Human-machine interfaces (HMIs)
• Industrial control systems (ICS)
• PLCs
• Distributed control systems (DCS)
• Industrial sensors and connected equipment

These systems often differ significantly from traditional IT environments.

Many production systems:

• Run outdated operating systems
• Depend on legacy software
• Cannot be patched frequently
• Require continuous uptime
• Depend on specialized vendors for maintenance

From an insurance perspective, these environments represent elevated risk because vulnerabilities can have direct operational consequences.

An email system outage is inconvenient.

A production line outage can stop revenue generation entirely.

The Insurance Gap Most Manufacturers Don’t See

Many manufacturing leaders assume that having cyber insurance automatically guarantees financial protection after an incident.

Unfortunately, policy language can be more complex.

Coverage may be affected by factors such as:

• Security control requirements
• Policy exclusions
• Scope of covered systems
• Documentation requirements
• Incident response obligations
• Reporting timelines

The challenge is that many organizations focus on purchasing coverage without fully understanding the conditions attached to it.

When an incident occurs, insurers often require evidence that specific controls were in place and functioning as represented during underwriting.

If security practices differ significantly from what was disclosed, claim disputes can arise.

This is one reason cybersecurity governance has become increasingly important. It is no longer enough to simply state that controls exist. Organizations must be able to demonstrate that controls are implemented, maintained, tested, and documented.

Backup Testing: One of the Most Overlooked Requirements

Backups are frequently listed as a key ransomware defense.

However, insurers increasingly want proof that backups are more than just configured.

They want evidence that organizations regularly test recovery capabilities.

Questions may include:

• How often are backups tested?
• Can production systems be restored successfully?
• How long does restoration take?
• Are backups isolated from ransomware attacks?
• Are critical operational systems included in backup strategies?

Many organizations discover gaps only during an actual recovery event.

A backup that cannot restore a production environment quickly may not provide meaningful business protection.

Regular testing helps organizations reduce downtime while demonstrating risk maturity to insurers.

---

Vendor Access Is Becoming a Major Underwriting Concern

Modern manufacturing relies heavily on third-party vendors.

Equipment manufacturers, engineering firms, automation specialists, integrators, and remote support providers often require access to production systems.

While these relationships are necessary, they also create potential pathways for attackers.

Insurers increasingly assess:

• Remote access controls
• VPN usage
• Privileged account management
• MFA enforcement
• Third-party security requirements
• Vendor monitoring practices

Manufacturers frequently focus their security efforts on internal users while overlooking vendor connections that may have extensive system access.

Reducing uncontrolled third-party access can significantly improve both cyber resilience and insurability.

---

Incident Response Planning Is No Longer Optional

Many organizations have cybersecurity tools but lack a documented process for responding to incidents.

From an insurer’s perspective, this creates uncertainty.

A documented incident response plan helps organizations answer critical questions:

• Who leads the response?
• How is production affected?
• When are insurers notified?
• Who communicates with stakeholders?
• What systems receive priority recovery?
• When should outside experts be engaged?

Without a defined response strategy, organizations often lose valuable time during an incident.

For manufacturers, every hour of downtime can translate into substantial operational and financial impacts.

A tested incident response plan demonstrates preparedness and may improve both underwriting outcomes and operational resilience.

Why Premiums Are Increasingly Tied to Security Maturity

Cyber insurance pricing is becoming more risk-based.

Organizations that demonstrate stronger cybersecurity controls frequently position themselves more favorably during underwriting discussions.

While every insurer evaluates risk differently, common areas of assessment include:

Security Area	Why Insurers Care
MFA	Reduces account compromise risk
Network segmentation	Limits lateral movement
Endpoint monitoring	Improves threat detection
Backup validation	Supports recovery capability
Incident response planning	Reduces business impact
OT asset visibility	Improves risk management
Vendor access controls	Minimizes third-party exposure
Security awareness training	Reduces human error

This shift is changing how cybersecurity investments are evaluated.

Rather than viewing security solely as a cost center, leadership teams increasingly examine how investments influence:

• Risk reduction
• Insurance eligibility
• Premium costs
• Claim defensibility
• Production continuity

The Board-Level Conversation Is Expanding

Cybersecurity is no longer just an IT department concern.

Executive leadership teams and boards increasingly recognize that cyber incidents represent operational, financial, legal, and strategic risks.

For manufacturers, key questions now include:

• What production systems are most critical?
• What would a week of downtime cost?
• Are OT environments adequately protected?
• Can we demonstrate required controls to insurers?
• Do we have sufficient documentation if a claim occurs?
• How resilient are our recovery processes?

These discussions help organizations move beyond compliance checklists and toward comprehensive risk management.

Oklahoma Manufacturers Face Unique Challenges

Manufacturers across Oklahoma often operate a mix of modern and legacy technologies.

Many facilities include:

• Long-lived industrial equipment
• Specialized control systems
• Engineering workstations
• Remote vendor connections
• Operational technologies that were not originally designed with cybersecurity in mind

Upgrading these environments requires balancing security, operational continuity, and budget constraints.

At the same time, insurers are placing greater scrutiny on manufacturing organizations because operational disruptions can generate substantial losses.

This creates a growing need for security strategies that address both cyber threats and insurability requirements.

Preparing for the Next Renewal Before the Next Incident

The question many manufacturers should be asking is not simply whether they have cyber insurance.

The better question is whether they can confidently demonstrate the controls, processes, and documentation an insurer may expect before approving a claim.

Organizations that proactively evaluate their OT security posture often gain multiple benefits:

• Improved operational resilience
• Reduced production disruption risk
• Better incident response readiness
• Stronger insurance positioning
• Greater confidence during underwriting reviews
• More informed board-level decision-making

Cyber insurance is evolving from a financial product into a risk management framework that influences how manufacturers protect critical operations.

For Oklahoma manufacturers, the hidden risk may not be a ransomware attack alone. It may be discovering that the safeguards required to support a successful claim were never fully implemented or documented in the first place.

Organizations that align cybersecurity investments with operational resilience, insurance requirements, and business continuity objectives are often better positioned to navigate both the threat landscape and the increasingly complex world of cyber insurance.
