Use Case
Preventing Ransomware from
Shutting Down Production Lines
Industry: Manufacturing
No signup required!
One infected laptop is one network hop away from a stopped line. Shieldworkz closes that gap.
Modern manufacturing runs on connected PLCs, HMIs, historians, and IIoT sensors that were never designed to resist a targeted cyberattack. Shieldworkz gives plant engineering and security leaders full visibility into their OT environment, isolates it from corporate IT, and keeps production running ,without touching the maintenance schedule.
Manufacturing OT Security Challenges
Plant leaders are being asked to secure environments they were never given the tools to see:
No verified inventory of PLCs, HMIs, historians, and workstations on the floor
Vendor remote access running on shared, unmonitored credentials
OEM customers demanding IEC 62443 compliance evidence that doesn't exist
Line PLC firmware and legacy systems that haven't been reviewed in years
IT and OT networks flat and effectively unsegmented
Understanding the Manufacturing OT Risk Landscape
Manufacturing environments blend decades-old programmable logic controllers with newer IIoT sensors, MES integrations, and remote vendor connections, often on the same flat network as corporate IT. That convergence is efficient for operations and attractive to attackers. A single compromised IT endpoint can become the path to production-halting disruption, corrupted recipe data, or safety-relevant control loss. Without independent OT visibility, most plants cannot even quantify their real exposure.
Common Cyber Threats Affecting Manufacturing
Ransomware moving laterally from IT into OT
Compromised or shared vendor remote access sessions
Unpatched, unreviewed legacy PLC and HMI firmware
Industrial protocol abuse (PROFINET, Ethernet/IP, Modbus)
Insecure IIoT and sensor devices as an entry point
Insider misuse of standing administrative credentials
