Manufacturing environments connect Information Technology (IT) systems with Operational Technology (OT) networks to support automation, remote access, production monitoring, supply chain operations, and data exchange. Systems like Enterprise Resource Planning (ERP), manufacturing applications, engineering workstations, remote-access infrastructure, and industrial control systems depend on interconnected digital infrastructure to keep production running.
This connectivity also creates relationships between assets, identities, and exposures that security teams may previously have assessed separately. A compromised IT asset, exposed identity, or misconfigured network control can potentially create an attack path toward systems supporting critical manufacturing processes. For security teams, understanding these relationships is essential to map and monitor exposures that can lead to production delays, equipment disruption, and operational downtime.
In early 2025, a ransomware attack on Lee Enterprises disrupted the printing and distribution process, operational infrastructure, and important files across multiple production facilities.
The incident illustrates how cyberattacks can affect manufacturing operations beyond data loss or intellectual property theft. An attacker does not necessarily need to compromise a Programmable Logic Controller (PLC) directly. Weak segmentation, exposed identities, compromised remote-access systems, and unmanaged IT assets can increase the risk of unauthorized access to connected OT environments.
Manufacturers face several challenges when trying to assess exposure across interconnected IT and OT environments.
- Production continuity: OT environments prioritize safety, availability, and operational continuity. Security activities that are routine in IT environments may require additional controls and planning when applied to sensitive industrial systems.
- Organizational silos: IT security and OT engineering teams often operate with different priorities, processes, and ownership structures. Security teams may focus on vulnerabilities and attack techniques, while manufacturing teams must consider safety, production schedules, equipment limitations, and system availability.
- Legacy technology: Manufacturing environments can contain decades-old operating systems, proprietary firmware, and industrial devices that cannot support conventional security agents or frequent patching.
- Incomplete context: Security findings are often assessed individually. A vulnerability on an isolated system may present less immediate risk than a lower-severity exposure on an internet-facing asset that provides a route toward a critical production system.
- Complex connectivity: Remote access, identity systems, enterprise applications, engineering workstations, and network connections can create relationships between IT and OT environments that are difficult to understand from isolated security tools.
These conditions make it difficult to determine which exposures require immediate attention and which can be managed through existing controls or planned remediation.
Manufacturers can operationalize exposure management by combining safe visibility, business context, attack-path analysis, and continuous validation.
1. Establish Visibility Without Disrupting Production
Manufacturers need visibility across enterprise IT, cloud environments, external assets, and connected OT infrastructure. OT-specific discovery and monitoring should use production-safe methods that minimize the risk of disrupting sensitive systems and devices.
That visibility should then be combined with information about asset ownership, business criticality, identities, vulnerabilities, network relationships, and external exposure. A complete inventory provides the foundation for understanding how individual findings relate to the systems that support manufacturing operations.
2. Identify Critical Manufacturing Assets
Not every asset carries the same operational importance. Security teams should identify the systems whose compromise could affect production, safety, engineering operations, or critical business processes.
These may include industrial control systems, engineering workstations, manufacturing applications, remote-access infrastructure, identity systems, and other assets that support production operations.
Once critical assets are identified, security teams can assess whether existing exposures create realistic routes toward them. This provides a more useful basis for prioritization than treating every vulnerability or misconfiguration as an independent remediation task.
3. Prioritize Exposures Using Attack Paths and Business Context
A vulnerability list alone does not show how an attacker could reach a critical asset. Security teams should combine exploitability, asset criticality, identity relationships, network topology, external exposure, and attack-path analysis to determine which exposures can realistically be chained together.
For example, a vulnerability on an isolated system with no validated route to a critical production asset may warrant less immediate attention than an exposure on an internet-facing system that provides an attacker with an initial foothold and a potential route toward an identity or engineering workstation.
This approach helps manufacturers direct limited remediation resources toward exposures that create meaningful paths to high-value assets.
4. Align IT and OT Ownership
Exposure management also requires clear ownership across security, IT, networking, engineering, and plant operations. Manufacturers should establish clear responsibility for IT assets, OT systems, identities, network controls, and production-critical infrastructure.
When an exposure is identified, teams should be able to determine who owns the affected asset, who controls the relevant security mechanism, and who must approve remediation. Cross-functional workflows can help security teams and OT engineers assess the operational implications of remediation before changes are made to production environments.
5. Continuously Validate Security Controls and Attack Paths
Controls such as network segmentation, access restrictions, identity policies, and firewall rules can reduce the likelihood that an attacker will progress from IT into OT. However, their effectiveness depends on how those controls operate within the actual environment.
Production-safe validation can help determine whether segmentation, identity controls, and other defenses effectively restrict an attacker from progressing along identified attack paths. If a critical PLC or other OT system cannot be patched immediately, for example, manufacturers can validate whether the controls intended to prevent unauthorized access to that system are actually limiting the relevant attack path.
Continuous validation provides security and OT teams with evidence they can use to prioritize remediation and confirm that compensating controls remain effective.
CyberMindr helps manufacturers connect exposure data across external, IT, cloud, and identity environments to understand which exposures could contribute to realistic attack paths toward critical assets. Its production data also highlights the scale of visibility and exposure challenges manufacturers face.
The following metrics are derived from an anonymized analysis of CyberMindr's production data across 22 manufacturing and industrial organizations:
- Comprehensive Surface Discovery: CyberMindr's continuous discovery engine identifies an average of 163 previously undocumented assets per manufacturer, helping teams identify hidden shadow IT and exposed operational endpoints that may otherwise remain outside the security team’s visibility.
- External Exposure Visibility: 86% of manufacturers in the analysis maintained at least one publicly exposed management panel, highlighting how internet-facing administrative interfaces can create potential entry points into hybrid IT and OT environments.
- Real-World Path Validation: CyberMindr continuously validates multi-hop attack paths across cloud, IT, and external attack surfaces, helping security teams distinguish isolated findings from exposures that can realistically contribute to compromise.
CyberMindr's approach helps manufacturers move from individual exposure findings toward a contextual understanding of how exposures, identities, assets, and security controls interact. This gives security teams evidence they can use to prioritize remediation while accounting for the operational constraints of manufacturing environments.
Manufacturers need visibility across IT and OT environments to understand where exposures exist, but visibility alone does not establish their operational risk. The greater challenge is determining how those exposures relate to identities, network connections, security controls, and critical manufacturing assets.
An exposure-management approach that combines asset context, attack-path analysis, and continuous validation gives security teams a more precise basis for prioritization. It allows manufacturers to focus remediation on realistic routes to critical systems while accounting for the operational constraints of production environments.
For manufacturers, the objective is not simply to identify more vulnerabilities. It is to understand which exposures can contribute to a meaningful attack path, validate the controls protecting critical assets, and direct remediation where it can reduce the greatest operational risk.
Challenges include production continuity, organizational silos, legacy technology, incomplete context, and complex connectivity.
It ensures security controls effectively block attack paths to protect critical manufacturing assets.
