The Challenge: Securing Industrial Control Systems in Live Offshore Environments


The client sought to harden its offshore Operational Technology (OT) cyber security posture. However, the company faced limited inventory visibility, legacy operating systems, restricted offshore access, and the risk that intrusive activities could cause production shutdowns.

  1. Unmapped Legacy Devices: Control networks contained legacy devices without consolidated inventory records or verified backups
  2. Live Production Risk: Offshore systems run continuous industrial processes; intrusive security interventions risk tripping systems and causing costly downtime
  3. Ingrained Cultural Practises: Offshore engineering teams were often hesitant about security protocols that might interfere with daily platform operations

The Solution: Systematic OT Asset Discovery


Sword implemented a structured, non-disruptive discovery and remediation programme across offshore assets, auditing more than 90% of devices, creating recovery backups, scanning for malware, and hardening ports against unauthorised access.

Non-Intrusive Asset Inventorying

Identified and verified over 90% of previously untracked OT assets, reviewing Windows event logs without interrupting operations.

Threat Eradication & Backup Creation

Executed targeted malware scans, generated system recovery backups, and applied CIS security benchmarks.

Cultural Collaboration & Network Hardening

Worked closely with offshore engineers to explain the rationale behind security controls, while locking unused physical ports to prevent accidental or malicious breaches.

Measurable Business Outcomes


Commercial / Efficiency Gain

Created verified disaster recovery backups across critical devices, eliminating potential multi-million-pound production halts

Operational Resilience / Risk Mitigation

Inventoried >90% of offshore control systems, scanned for malware, and applied rigorous CIS benchmark controls

Speed, Agility & User Experience

Non-disruptive discovery protocols ensured comprehensive device inspection with zero downtime to operations

Future Proof Scalability & Independence

Cultural education and port-blocking controls empowered platform staff

"Sword’s expertise improved the client’s cyber security posture, ensuring compliance, operational resilience, and educating personnel on critical security measures effectively."

More Information

Automated IT vulnerability scanners can overwhelm sensitive serial connections and programmable logic controllers (PLCs), causing emergency shutdowns. Sword uses non-intrusive methods to ensure systems run safely.

Physically and logically locking unneeded USB and Ethernet ports on platform consoles stops unauthorised flash drives from introducing malware into isolated control networks
