This case study shows how Cybeneers helped a large manufacturing plant harden its OT environment, reduce vulnerabilities by 75%, and improve safety — all while keeping production running smoothly.
Client Overview
A major manufacturer producing mission-critical industrial components relied on:
- Complex OT systems
- Legacy ICS devices
- Continuous, high-output production lines
With growing digital connectivity, leadership recognized their attack surface was increasing — and so was the risk to safety and operational continuity.
The Challenge
Before approaching Cybeneers, the plant faced several issues:
- Legacy OT devices riddled with vulnerabilities
- No segmentation between IT and OT
- Limited monitoring in OT networks
- Safety risks tied to compromised controllers
- Compliance pressure mounting
The plant knew the risks were growing — but didn’t know where to start without interrupting production.
Cybeneers’ Solution
OT Security Assessment
- Vulnerability analysis of PLCs, HMIs, and ICS devices
- OT network architecture mapping
- Policy and governance review
- Remote access evaluation
This revealed where the gaps were — and which posed real operational risk.
OT Security Hardening
- Strict network segmentation between IT and OT
- Configuration hardening on ICS devices
- OT-focused intrusion detection systems (IDS)
- Secure remote access with MFA and session logging
- Real-time anomaly monitoring tools
These improvements tightened OT security without disruption.
Security Awareness Training
- OT-specific threats & warning signs
- Safe remote access
- ICS device protection
- Best practices for daily operations
This helped build a strong security culture across teams.
Implementation Approach: Zero-Disruption Security
- All hardening scheduled around production cycles
- Changes tested in controlled segments before rollout
- Clear and continuous operational communication
Result: Not a single production delay or outage.
The Results
Legacy OT weaknesses eliminated.
Zero production disruption.
Detection time cut by 50%.
Reduced cyber-triggered incidents.
Clear asset & anomaly insight.
Long-term roadmap delivered.
Client Testimonial
“Cybersecurity wasn’t top of mind for us — until we realized how exposed our OT systems actually were. Cybeneers secured them without disrupting production.”
