Data Exfiltration Prevention for Manufacturing: Stopping Industrial Espionage and IP Theft
The 2024 Verizon DBIR confirmed that 30% of manufacturing breaches involved espionage-motivated attacks — the highest of any sector — with intellectual property theft as the primary objective. When Norsk Hydro suffered the LockerGoga ransomware attack in 2019, the cost exceeded $75 million and forced the company to switch 35,000 employees to manual operations. UK manufacturers hold trade secrets, process designs, customer specifications, and supply chain data that competitors and nation-state actors actively seek to steal.

The Industrial Espionage Threat to UK Manufacturing
Manufacturing intellectual property — process designs, engineering drawings, tooling specifications, formulation data, and supplier pricing — represents decades of competitive advantage compressed into files that can be exfiltrated in minutes. The NCSC has repeatedly warned that UK manufacturers are targeted by nation-state actors seeking to acquire advanced manufacturing techniques, defence-related technologies, and proprietary processes. Criminal ransomware groups target manufacturers because operational disruption creates extreme urgency to pay. The convergence of OT/IT systems means that a single compromised endpoint can provide access to both corporate data and production systems.
OT/IT Convergence Creates New Exfiltration Pathways
Modern manufacturing environments increasingly connect operational technology (OT) systems — PLCs, SCADA, HMIs, and industrial IoT sensors — to IT networks for monitoring, analytics, and remote management. This convergence creates data exfiltration pathways that did not exist when OT was air-gapped. An attacker who compromises a corporate endpoint can potentially reach production data, quality control records, and process parameters. BlackFog addresses this by preventing data from leaving endpoints regardless of where it originated — whether the source is a corporate file server, an ERP system, or a connected OT data historian.

- Process parameters and manufacturing recipes
- Quality control data and testing records
- Supply chain pricing and supplier contract details
- Customer specifications and order data
- ERP system data including financial and operational records
NIS2 and Regulatory Obligations for Manufacturers
The EU NIS2 Directive classifies many manufacturing sub-sectors as essential or important entities, requiring enhanced cybersecurity measures including data protection controls. UK manufacturers operating in EU markets or supplying EU customers must comply. The UK's own NIS Regulations apply to operators of essential services, and the forthcoming Cyber Security and Resilience Bill will extend obligations further. Defence manufacturers face additional requirements under DEFSTAN 05-138 and the MOD Cyber Security Model. BlackFog provides the data exfiltration prevention control that satisfies the data protection requirements across all of these frameworks.
- NIS2: data protection and incident reporting for essential and important entities
- UK NIS Regulations: cybersecurity measures for operators of essential services
- DEFSTAN 05-138: MOD cyber security requirements for defence supply chain
- Cyber Essentials Plus: baseline certification increasingly required by procurement frameworks
- ISO 27001: information security management expected by enterprise customers
- ITAR/EAR: export control compliance for manufacturers handling controlled technologies
How BlackFog Protects Manufacturing Operations
BlackFog deploys on all IT endpoints across manufacturing organisations — engineering workstations, administrative systems, remote-access laptops, and any device connected to the corporate network. It monitors outbound data flows in real time, blocking any unauthorised transfer of design files, process data, or corporate information. For manufacturers with mixed OT/IT environments, BlackFog protects the IT-side endpoints that serve as the bridge between corporate networks and production systems, preventing attackers from exfiltrating data acquired through OT/IT convergence points.
Frequently Asked Questions
Does BlackFog protect against industrial espionage?
Yes. BlackFog prevents the exfiltration phase of any espionage attack. Whether the attacker is a nation-state actor, a criminal group, or a malicious insider, BlackFog blocks the unauthorised transfer of intellectual property, design files, and trade secrets from company endpoints.
Can BlackFog be deployed on OT systems?
BlackFog is designed for IT endpoints (Windows, Mac, etc.). It does not deploy directly on OT systems like PLCs or SCADA controllers. However, it protects the IT endpoints that connect to OT networks, preventing data from being exfiltrated via the IT/OT convergence pathway that attackers exploit.
How does BlackFog handle large CAD file transfers that are part of normal business?
BlackFog distinguishes between legitimate business data transfers and exfiltration attempts using AI-driven analysis. Approved destinations — such as customer portals, supply chain platforms, and cloud storage — are whitelisted. Only transfers to unauthorised or suspicious destinations are blocked.
