In a recent ProFood World article on 2026 cybersecurity trends, E Tech Group was highlighted for our leadership in modern OT security practices, specifically through a real-world case study we published on how proactive IT/OT architecture protected a food and beverage manufacturer from a cyberattack. The article underscores a shift across the industry: OT cybersecurity is no longer a reactive IT concern; it has become a core operational priority for manufacturers navigating digital transformation.
The 2025 SANS State of ICS/OT Security Survey shows that threat detection and visibility tools are making a measurable impact, with nearly half of incidents detected within 24 hours and more than half contained within 48 hours. But the same study reinforces a persistent challenge: visibility gaps deep in the ISA‑95 stack, especially at PLC, SCADA, and HMI layers, where operational disruption is most damaging.
At the same time, IT teams, often managing aging infrastructure, legacy devices never designed for connectivity, and shrinking OT expertise from retirements, are increasingly driving cybersecurity investment. As IT and OT converge, manufacturers must prioritize asset inventory, segmentation, and continuous monitoring as foundational OT security practices.
Industry Challenges: Visibility, Context, and Slow Remediation
Despite progress, manufacturers still face critical obstacles:
- Many plants lack complete, accurate OT asset inventories.
- Teams struggle to understand device criticality, lifecycle status, and vulnerabilities.
- Remediation timelines remain long—some attacks take weeks or months to resolve.
Experts from Claroty, Emerson, Rockwell Automation, and Dragos consistently emphasize:
- Stronger network segmentation and controlled remote access
- Protocol‑aware monitoring for OT networks
- The limits of IT‑centric tools in identifying or classifying OT assets
- The significant operational and financial risk tied directly to cyber recovery timelines
E Tech Group Case Study: Stopping a Cyberattack Before It Reached Operations
The ProFood World article spotlights an E Tech Group case study—also published on our website as “Cybersecurity Best Practices Save Critical Infrastructure” as an example of today’s evolving OT security expectations.
In the incident, a food and beverage manufacturer experienced suspicious lateral movement between an IT domain controller and backup system—an early-stage ransomware tactic. Because of E Tech Group’s IT/OT cybersecurity architecture, the attack never reached OT assets.
What E Tech Group Implemented
- Air‑gapped network design separating IT and OT
- Enhanced OT firewalling with role‑based access restrictions
- Protocol filtering, segmentation, and zoning
- Continuous network monitoring and logging
- Deep-OT threat detection engine watching for abnormal or malicious behavior
This defense-in-depth approach allowed the plant to remain fully operational, isolating the threat to the enterprise network while preventing production impact.
As Solutions Architect, Kevin Romer, noted in the article:
“Without the threat detection engine, attackers could have remained unseen much longer—gaining deeper knowledge of the facility before launching a full‑scale attack.”
This case demonstrates precisely what manufacturers now require: preventive architecture paired with real‑time OT-aware detection.
Looking Ahead: IT‑OT Knowledge Sharing Is Essential
With retirements accelerating and newer IT-trained personnel entering manufacturing environments, cross-training between IT and OT teams is critical. Experts highlight the need for:
- Documented OT security controls
- Identity and access management frameworks
- Consistent segmentation strategies
- Shared response models across IT and OT
Executives increasingly frame OT cybersecurity as both an operational risk and a financial risk—one directly tied to uptime, production continuity, and corporate responsibility.
E Tech Group’s Perspective
ProFood World’s feature reinforces what we experience across customer sites every day: effective OT cybersecurity demands deep domain expertise, IT/OT convergence, and operationally grounded security architecture.
Our case study highlights how thoughtful design, visibility, and OT-first threat detection can make the difference between a contained IT incident and a plant-wide crisis.
E Tech Group remains committed to helping manufacturers:
- Build resilient, segmented OT networks
- Implement advanced detection and response tools
- Strengthen asset inventory and vulnerability visibility
- Train the next generation of IT and OT professionals
- Align cybersecurity strategy with operational outcomes
In 2026, OT cybersecurity isn’t just about protecting data; it’s about protecting production, safety, and profitability. And E Tech Group is proud to be recognized for leading the way.
