Manufacturing IT & Cybersecurity
Modern manufacturing runs on connected systems. PLCs, SCADA networks, MES platforms, and ERP systems form a digital backbone that drives productivity — but also creates attack surfaces that legacy security tools were never designed to protect. Petronella Technology Group bridges the gap between operational technology (OT) and information technology (IT) security, delivering solutions that protect production floors, secure supply chains, and achieve compliance with CMMC, NIST, and industry-specific frameworks.

The OT/IT Convergence Security Gap
Manufacturing cybersecurity is fundamentally different from enterprise IT security. The convergence of operational technology and information technology creates unique risks that generic security solutions cannot address.
Operational Technology (OT)
- PLCs, SCADA, DCS, HMIs that control physical production processes
- Systems that may run Windows XP or proprietary RTOS because vendor patches would require production shutdown
- Uptime is paramount — minutes of downtime cost thousands of dollars
- Safety-critical systems where a cyber compromise can cause physical harm
- 25+ year equipment lifecycle vs. 3-5 year IT refresh cycles
BRIDGE
THIS
Information Technology (IT)
- ERP, MES, email, file servers, cloud services used for business operations
- Regular patching cycles, modern operating systems, endpoint protection
- Confidentiality and integrity are primary concerns
- Remote access for vendors, customers, and remote employees
- 3-5 year refresh cycles with planned migrations
When OT and IT networks connect — for production data collection, remote monitoring, or ERP integration — a breach on the IT side can cascade into production shutdown. A ransomware attack that started in an accounting department email can end with production lines stopped and safety systems compromised. We design security architectures that enable the connectivity manufacturers need while preventing this cross-domain contamination.
Why Manufacturing Is the Most Attacked Industry
Manufacturing surpassed financial services as the most attacked industry in 2021 and has held that position since. The combination of high-value intellectual property, low downtime tolerance, and legacy systems creates an irresistible target profile.
Ransomware Halting Production
Manufacturing companies pay ransoms at higher rates than any other industry because production downtime is so costly. An average manufacturing ransomware incident causes 21 days of disrupted production, resulting in millions in lost revenue, missed delivery deadlines, contractual penalties, and damaged customer relationships. Our layered defense prevents ransomware from reaching production systems.
IP Theft & Industrial Espionage
Nation-state actors and competitors target manufacturers to steal product designs, formulations, manufacturing processes, and pricing data. Advanced persistent threats (APTs) can dwell in manufacturing networks for months, exfiltrating CAD files, process parameters, and proprietary formulations. The stolen intellectual property often resurfaces in competing products manufactured overseas.
ICS/SCADA Attacks
Attacks directly targeting industrial control systems are no longer theoretical. Threat groups like TRITON/TRISIS have demonstrated the capability to manipulate safety instrumented systems. A compromised PLC can alter product specifications, damage equipment, or create safety hazards. These attacks require specialized OT security expertise — not just traditional IT security tools.
Supply Chain Compromise
Manufacturers depend on a complex web of suppliers, and attackers increasingly target the weakest link in that chain. A compromised component supplier, software vendor, or logistics partner can provide a backdoor into your production environment. The SolarWinds and Kaseya attacks demonstrated how supply chain compromises can cascade to thousands of downstream victims.
IT & Cybersecurity Services for Manufacturers
Our manufacturing cybersecurity practice combines IT security expertise with operational technology knowledge to protect both your business systems and your production floor.
OT/ICS Security Assessment & Monitoring
You cannot protect what you cannot see. Most manufacturers have incomplete visibility into their OT environment — legacy controllers, undocumented network connections, and vendor remote access points that were installed years ago and forgotten.
OT Security Assessment Deliverables
- Complete OT asset inventory: Passive network discovery of every PLC, HMI, SCADA server, RTU, and engineering workstation on your OT network, including firmware versions, communication protocols, and network connections
- Network architecture review: Mapping of data flows between OT and IT networks, identifying unauthorized connections, unnecessary pathways, and opportunities for improved segmentation
- Vulnerability assessment: Identification of known vulnerabilities in OT devices and software without active scanning that could disrupt production. We use passive monitoring and vendor advisory databases
- Risk prioritization: Practical risk ratings that account for both cybersecurity exposure and production impact, helping you prioritize investments that reduce the most risk without disrupting operations
- Continuous OT monitoring: Ongoing passive monitoring of OT network traffic to detect anomalous commands, unauthorized changes to controller logic, new devices, and potential attack indicators
Network Segmentation & Industrial DMZ
The Purdue Model and ISA/IEC 62443 provide frameworks for segmenting industrial networks, but implementing them in a brownfield manufacturing environment — where production cannot stop — requires careful planning and phased execution.
Segmentation Architecture
- Industrial DMZ: A demilitarized zone between OT and IT networks that allows necessary data exchange (production metrics, quality data, inventory levels) while preventing direct connectivity between enterprise IT and production floor systems
- Zone-based segmentation: Dividing the OT network into security zones based on function and criticality — safety systems isolated from process control, process control isolated from supervisory systems
- Micro-segmentation: Where possible, isolating individual production cells or critical systems into their own network segments with controlled, monitored communication paths
- Secure remote access: Jump servers and encrypted tunnels for vendor remote access that provide full session recording, time-limited access, and multi-factor authentication — replacing the VPN connections that many vendors installed with no security controls
CMMC Compliance for Defense Manufacturers
Manufacturers in the defense industrial base (DIB) must achieve CMMC certification to continue bidding on and performing DoD contracts. For manufacturers, CMMC compliance presents unique challenges because CUI (Controlled Unclassified Information) often flows through production systems — CAD files on engineering workstations, technical data packages on MES platforms, and specifications embedded in CNC machine programs.
Manufacturing CMMC Services
- CUI scoping for manufacturing: Identifying where controlled technical data lives across your IT and OT environments — including engineering systems, production planning tools, and quality management platforms
- Gap assessment: Evaluating your current environment against CMMC Level 2 requirements (110 NIST 800-171 controls) with a manufacturing-specific focus
- SSP and POA&M development: Creating your System Security Plan and Plan of Action & Milestones with the specificity that C3PAO assessors expect
- Technical implementation: Deploying the security controls required for CMMC certification — encryption, access controls, monitoring, incident response — without disrupting production workflows
- C3PAO assessment preparation: Pre-assessment reviews, evidence collection, and readiness testing so your organization passes the first time
Managed IT & Enterprise Security
Beyond OT-specific security, manufacturers need robust IT infrastructure that supports ERP, email, file sharing, CAD/CAM workstations, and business applications — all secured against the threats targeting manufacturing organizations.
- ERP system security: Protection for SAP, Oracle, Epicor, Infor, and other manufacturing ERP platforms that contain proprietary pricing, customer data, and production information
- Engineering workstation security: Hardened configurations for CAD/CAM workstations that balance the performance requirements of design software with security controls that protect intellectual property
- 24/7 SOC monitoring: Our SOC-as-a-Service monitors both IT and OT environments from a unified security operations platform, correlating events across domains to detect sophisticated attacks
- Backup and disaster recovery: Tested backup and recovery procedures for both IT systems and critical OT configurations (PLC programs, HMI configurations, recipe databases) with RTOs that minimize production impact
Industry 4.0 & Smart Factory Security
Industry 4.0 initiatives — IIoT sensors, digital twins, predictive maintenance, AI-driven quality control — deliver enormous productivity gains but dramatically expand the manufacturing attack surface. Each connected sensor, each cloud analytics platform, and each mobile dashboard is a potential entry point.
- IIoT device security: Secure deployment and monitoring of industrial IoT sensors, gateways, and edge computing devices with network segmentation, firmware management, and anomaly detection
- Cloud manufacturing platform security: Securing data flows between factory floor systems and cloud analytics platforms (Azure IoT, AWS IoT, Siemens MindSphere) with cloud security posture management
- AI and ML model protection: Securing AI and machine learning systems used in quality control, predictive maintenance, and process optimization from adversarial manipulation and data poisoning
- Digital twin security: Protecting digital twin environments that mirror physical production systems, preventing attackers from using digital twins to plan attacks against physical infrastructure
Manufacturing Compliance Frameworks
Manufacturing compliance requirements vary based on your industry, customers, and the type of data you handle. We align your security program with the frameworks that apply to your specific operation.
CMMC / NIST 800-171
Required for defense manufacturers handling CUI. CMMC Level 2 requires implementation of 110 security controls from NIST 800-171. We have deep expertise in manufacturing-specific CMMC implementation.
DFARS 252.204-7012
The Defense Federal Acquisition Regulation Supplement clause that requires adequate cybersecurity for covered defense information. This is the current contractual requirement while CMMC rulemaking is finalized.
IEC 62443
The international standard for industrial automation and control system (IACS) security. We use IEC 62443 as the framework for OT security assessments and network segmentation design in manufacturing environments.
NIST CSF
The NIST Cybersecurity Framework provides a flexible, risk-based approach suitable for manufacturers of all sizes. We use NIST CSF as the foundation for security programs at non-defense manufacturers.
ISO 27001
International standard for information security management systems. Often required by automotive (TISAX), aerospace, and pharmaceutical customers as a condition of supplier qualification. We support certification readiness.
ITAR / EAR
International Traffic in Arms Regulations and Export Administration Regulations impose cybersecurity requirements on manufacturers handling defense articles or dual-use technology. We implement the technical controls required for ITAR/EAR compliance.
Protecting Manufacturing Operations
Scenario: Precision Manufacturer Achieves CMMC Level 2
A 150-employee precision machining company in the Research Triangle Park area had been a Tier 2 defense supplier for 15 years. With CMMC requirements approaching, they needed to achieve Level 2 certification to retain their DoD contracts — contracts representing 60% of their revenue.
The challenge: CUI flowed through their engineering CAD workstations, CNC machine controllers (via G-code files containing technical specifications), their ERP system (Epicor), and email. Their OT network had no segmentation from IT, and vendor VPN connections provided direct access from the internet to production systems.
Over six months, we deployed network segmentation creating a proper industrial DMZ, migrated their email and file sharing to an enclave environment for CUI processing, implemented endpoint detection on all workstations and servers, established 24/7 monitoring through our SOC, and developed the required security documentation. They passed their C3PAO assessment on the first attempt and secured a new five-year DoD contract within three months of certification.
Scenario: Food Manufacturer Stops Ransomware at the IT/OT Boundary
A food processing facility received a phishing email that installed ransomware on an accounting workstation. The ransomware began encrypting files and scanning the network for additional targets. Because we had deployed network segmentation between IT and OT, the ransomware could not reach production line controllers, batch management systems, or food safety monitoring equipment. Our SOC detected the lateral movement within eight minutes and isolated the affected IT segment. Production continued uninterrupted while the IT environment was cleaned and restored from backups within 18 hours. Without segmentation, the entire facility — including HACCP monitoring systems — would have been compromised.
