Trusted across critical infrastructure and OT environments
Supporting organisations operating distributed, high-dependency infrastructure where operational resilience and secure data transfer are essential.
Cybersecurity threats in the manufacturing industry
Ransomware, compromised supplier connections and poorly governed IT-OT links can disrupt production. The practical challenge is to make operational data available without giving a compromise an unnecessary route into critical systems. This starts with controlling what data crosses each boundary, where it goes and whether a return path is needed.
THE MANUFACTURING SECURITY CHALLENGE
Make production data available without increasing cyber risk
Cloud analytics, automation, centralised monitoring, remote engineering and connected supply chains all rely on data from the plant. At the same time, manufacturers need to prevent cyber threats from travelling in the opposite direction.
The security question is not whether manufacturing data should move. It is what should cross the production boundary, in which direction and under what policy.

WHY MANUFACTURERS ARE ACTING NOW ON CYBERSECURITY
Connectivity is expanding. The trust boundary should not.
01
Cloud, automation and Industry 4.0
Production telemetry is increasingly required for analytics, AI, automation, digital twins and enterprise platforms. However, every new connection can introduce another vulnerability or pathway into operational technology if not properly governed.
Cybersecurity for manufacturing must therefore support digital transformation while controlling how data moves between OT, IT and cloud environments.
02
Centralised operations
Monitoring, engineering, and security teams need consistent visibility across multiple plants, which means manufacturing cybersecurity strategy must scale across sites, not just protect one.
Connecting relevant logs, events and telemetry to SOC and SIEM environments can help security teams detect suspicious activity, generate alerts and investigate security incidents before they develop into major operational disruptions. Combining real-time monitoring with threat intelligence can help manufacturers identify suspicious activity and respond to emerging cyber threats more effectively.
03
OEM and supplier support
OEMs and suppliers may need equipment status, diagnostics, logs or files to support a plant. Give them the approved information they need, while limiting unnecessary exposure of production systems and sensitive details.
04
Legacy and regulated estates
Older assets may not support modern security tools, security agents or conventional patching processes, which can create vulnerabilities that cyber criminals can exploit.
Rather than forcing disruptive changes to critical equipment, cybersecurity controls can be applied around the asset through segmentation, policy enforcement and protocol-aware inspection.
MANUFACTURING CYBERSECURITY USE CASES
Secure the data flows that support modern manufacturing.
Effective cybersecurity for manufacturing is about more than protecting individual devices. It requires control over how data, users and systems interconnect across the production environment. 4Secure helps manufacturers reduce unnecessary exposure while maintaining the connectivity needed for automation, monitoring, analytics and modern manufacturing operations.
OT data into IT and cloud
Release approved production data to MES, ERP, historians,
maintenance platforms, digital twins, AI and cloud analytics
without extending trust back into the plant.
Support automation and digital manufacturing while maintaining
separation between zones of trust.
OT visibility for SOC and SIEM
Send relevant events, logs and telemetry to monitoring teams
while keeping operational systems isolated from unnecessary
enterprise access.
Improve real-time visibility and help security teams detect
potential cyber threats without creating an unnecessary route
into OT.
Controlled OEM and supplier exchange
Share diagnostics, files and equipment status without broad
inbound access or unnecessary exposure of recipes, set points,
production volumes, plant identifiers or intellectual property.
Give third parties the information they need, without exposing
more of the plant than necessary.
Protection for legacy production systems
Place modern policy enforcement and protocol handling at the
trust boundary so older PLC, DCS, SCADA, CNC and laboratory
systems can remain isolated.
Exchange operationally required data without forcing
wholesale replacement.
Secure site-to-site data transfer
Apply repeatable connectivity and security controls across
mixed-vendor plants, acquired estates and factory-to-factory
data flows.
Reduce exposure across interconnected manufacturing operations
and help mitigate lateral-movement risk.
Secure IoT and edge-to-cloud connectivity
Process and buffer data locally, then move only approved telemetry
or outputs from distributed production sites into cloud
environments.
Support the Internet of Things and smart manufacturing while
controlling what leaves the production environment.

SECURE DATA MOVEMENT IS MORE THAN CONNECTIVITY
Control the data, the direction and the route between zones of trust
4Secure defines the exchange requirement first, then designs the architecture around data sensitivity, production criticality, and required assurance.
THE 4SECURE APPROACH TO MANUFACTURING CYBERSECURITY
The right level of assurance for each data flow
One manufacturing environment can require several control patterns. We select around the flow and operational risk, rather than forcing every requirement into one product.
Policy controlled
01
Inspect and transform approved data
TrustedFilter
For supported structured data flows, TrustedFilter® can validate approved data and remove, mask, generalise or redact sensitive fields before release.
BEST CONSIDERED FOR
Reporting, analytics and controlled partner sharing
Edge to cloud
02
Process at the edge. Control what moves to the cloud.
CloudExchange + AWS IoT Greengrass
AWS IoT Greengrass supports local processing and messaging for distributed production sites, including buffering where connectivity is intermittent. CloudExchange and the wider 4Secure solution provide a controlled route for approved telemetry or outputs to reach cloud environments.

Frequently Asked Questions
What is cybersecurity in the manufacturing industry?
It’s the practice of protecting the systems, data and connections used across production environments, including operational technology (OT) such as PLCs, SCADA and DCS, alongside IT, cloud platforms and third-party connections, from unauthorised access, disruption or compromise, while still allowing the data flow the business depends on.
Why is manufacturing such a common target for cyberattacks?
Manufacturing combines a high reliance on continuous operations with legacy technology that often can’t be patched or updated like standard IT systems. Downtime has an immediate financial cost, which makes manufacturers attractive targets for ransomware, and complex supplier networks create multiple entry points that are harder to monitor and control.
What's the difference between OT security and IT security?
IT security primarily protects data confidentiality and integrity. OT security prioritises availability and safety: a control system going offline can halt production or create a safety incident, so OT security focuses on isolation, monitored data exchange and minimising any return path into the plant, rather than just patching and endpoint protection.
What are the most common cybersecurity threats facing manufacturers?
The most frequent risks include ransomware spreading from IT into OT networks, compromised remote access used by OEMs or suppliers, unsecured IoT and edge devices, and lateral movement between poorly segmented zones. Legacy equipment that can’t run modern security agents is also a persistent weak point.
How can manufacturers secure legacy OT systems that can't be patched?
Rather than modifying the legacy asset itself, protection is typically applied at the boundary around it, using policy enforcement, protocol-aware inspection, and segmentation to control what data can enter or leave that zone. This allows older PLC, SCADA, DCS and CNC systems to stay in service without being exposed to modern network risk.
Does improving manufacturing cybersecurity mean restricting access to production data?
Not necessarily. The goal is controlled access rather than no access: deciding what data crosses the production boundary, in which direction, and under what governance, so cloud analytics, SOC monitoring and supplier diagnostics can still function without creating uncontrolled routes back into the plant.
What should a manufacturer do first to improve their cybersecurity posture?
Start by mapping the data flows that already exist or are planned: what needs to move, where it needs to go, which systems are involved, and whether a return path is acceptable. This makes it possible to apply a proportionate level of control to each flow, rather than a single blanket policy across the whole environment.
