Cybersecurity for industry & manufacturing
Industry 4.0 cybersecurity for factories that cannot afford downtime.
The manufacturing industry has been one of the most attacked sectors worldwide for several years. Ransomware figures show that manufacturing is consistently at the top – in some reports accounting for 20–26% of all attacks.
That is no coincidence. Factories are attractive targets:
- everything runs on availability – downtime is direct damage;
- OT systems are often old, poorly documented, and hard to patch;
- Industry 4.0 creates even more connections, sensors, remote access, and cloud – with extra attack surface as a result.
No wonder people search for ransomware manufacturing Netherlands, OT IT convergence security, and industry 4.0 cybersecurity.
> OT/IT convergence: great for efficiency, painful for security
Where production lines used to be more or less “air-gapped”, PLCs, SCADA, MES, and quality systems now sit on the same network as ERP, Office, and cloud. Convenient for data and reporting, but risky when the basics are not in order.
Reports on OT security show:
- manufacturing is a top target for industrial ransomware;
- IT/OT convergence is rarely well designed;
- less than half of manufacturers feel well prepared for OT security.
Meanwhile, the NCSC describes very concretely the need to secure OT/IACS: segmentation, asset inventory, monitoring, and incident preparation. OT IT convergence security is therefore not a buzzword, but often your biggest risk.
> Typical threats in production environments
Ransomware on production networks
First “only” IT, then file servers for recipes and drawings, and eventually systems that control or monitor production lines.
Abuse of remote access
Suppliers who can log in to PLCs, HMIs, or engineering stations with shared accounts – often via old VPNs or appliances with known vulnerabilities.
Shadow connections and temporary solutions
One-off data scripts, shared folders, USB sticks, old FTP servers for machines – all became permanent and rarely well managed.
Human factor on the factory floor
Operators who “just” turn something off, engineers who quickly create a bypass, contractors with admin rights. As the NCSC says: humans are either the problem or the solution.
Supply chain risk
A compromise at a supplier or engineering firm can directly affect your own OT environment and production.
> How Neo Security helps industry & manufacturing
We grew up among patch panels, not in the boardroom. We combine offensive OT/IT knowledge with realistic governance. No generic industry 4.0 cybersecurity slides, but tests and measures that keep your lines running.
1. OT/IT inventory & risk analysis
You cannot secure what you cannot see. Together with your engineers, we map out:
- all OT assets: PLCs, SCADA/DCS, HMIs, robots, sensors, engineering stations;
- connections with IT (ERP, MES, historians, reporting, remote access);
- dependencies per production line or plant.
Result: a practical risk analysis answering:
- what is truly mission critical?
- where is the fastest route for an attacker?
- which measures deliver the most risk reduction per euro?

2. Pentests & red teaming with OT scenarios
We do not just test a website, but the entire chain around it:
- Pentests on remote access, engineering gateways, OT management systems, and supporting IT components (AD, jump servers, VPN). More about pentests: penetration testing
- Red team operations targeting outage or manipulation of production, including lateral movement from IT. More about red teaming: red team operations
Always with strict rules of engagement and in consultation with production & safety, so you do not introduce unnecessary risks.
3. Industry 4.0 cybersecurity: design & hardening
Many industrial environments are in the midst of digitalisation: IIoT, OEE dashboards, predictive maintenance, cloud connections, and data lakes. Great innovations – until one vulnerable sensor or gateway becomes the entry point.
- Design and implementation of segmentation between IT, OT, and cloud.
- Hardening of OT systems and management layers (accounts, logging, patch policy).
- Secure integration of MFT solutions and data flows for production data, for example with GoAnywhere MFT.
- Integration with existing security tooling (SIEM/XDR/Threat Brain) for OT logging and detection. See also Threat Brain.
This way, industry 4.0 cybersecurity becomes not a marketing term, but a concrete design.
4. 24/7 monitoring, incident response & forensics
Ransomware in manufacturing rarely arrives on Monday at 10:00. It happens at night, on weekends, or during maintenance.
- Blue Team-as-a-Service / Managed SOC with OT/industry use-cases: anomalies in remote access, suspicious config changes, data exfil outbound, etc. More about SOC: Blue Team-as-a-Service and managed SOC.
- Incident Response when things go wrong – including collaboration with your own engineers, suppliers, and insurer. More about response: incident response
- Digital Forensics to reconstruct what happened and which locations or lines were affected. See also digital forensics.
Lessons learned are linked back to your OT IT convergence security and risk framework.
5. People & organisation: tabletop & awareness
A good industrial security strategy does not stop at technology:
- Tabletop exercises with management, plant managers, IT/OT, and HSE: what do we do when a line goes down due to ransomware? Which decisions do we make when? More about exercises: tabletop exercises
- Targeted awareness & phishing campaigns for engineers, operators, and contractors – with scenarios from the factory, not from a generic office environment. More about phishing: phishing-as-a-service
> Why industry & manufacturing chooses Neo Security
- We come from engineering.
Not just IT; we have been working for years in environments with OT, SCADA, MFT, and complex chains. We understand that a mistake is not a “bug”, but can mean a production line standing still. - Offense + defense + governance in one story.
Pentests and red teaming provide input for your risk register, CIS/ISO controls, and NIS2 approach – not three separate tracks. - Not with fear, but with facts.
You get an honest picture of your risks, including “this is urgent now” versus “we will address this in the next phase.” No panic, just priority.
Our offensive power, your strongest defence - even when the production line is running.

One conversation is enough to determine whether an OT scan, red team, monitoring, or tabletop exercise is the best first step. We look at your production lines, OT/IT connections, and existing measures.
