Industrial control systems (SCADA, PLCs, HMIs) were not designed with cybersecurity in mind — and connecting them to corporate networks creates serious vulnerabilities. At the same time, manufacturers need real-time visibility across both environments. Group 4 Networks designs OT/IT architectures that provide that visibility without exposing production systems to enterprise threats — and without requiring you to manage two separate IT providers.
Many industrial control systems run on Windows XP, Windows 7, or proprietary embedded OS versions that cannot be patched or updated without disrupting production. We isolate these systems using network segmentation and compensating controls — firewalls, unidirectional gateways, and network monitoring — so they cannot be reached from the corporate network without removing the risk of patching.
Engineers, OEM vendors, and remote technicians frequently need access to production systems for maintenance and troubleshooting. We implement purpose-built industrial remote access solutions (Claroty, Secomea, Tosibox) that provide time-limited, session-recorded, auditable access to specific OT assets — without using the same VPN that provides general corporate access.
Ransomware that encrypts corporate IT can propagate to production networks if segmentation is inadequate — stopping production lines entirely. We design network architectures where a corporate IT incident cannot propagate to the factory floor, and document incident response playbooks that prioritize production restoration even if corporate systems remain encrypted.
Manufacturers need real-time production data flowing from Manufacturing Execution Systems (MES) on the factory floor into ERP systems in the corporate office. We design and implement secure integration architectures using DMZ data brokers that allow data to flow in one direction — from OT to IT — without creating a pathway attackers can exploit in reverse.
Manufacturing became one of the most attacked sectors globally due to low OT security maturity and high willingness to pay ransoms to restore production. A single attack that stops a production line for 24–72 hours can cost more than an entire year of managed IT services.
Manufacturing operations run shifts that start at 5 AM and end at midnight. Our Self-Healing IT platform monitors your production systems around the clock — detecting and remediating issues before your production line feels them.
