Cybersecurity Assessment

FOX delivers structured industrial cybersecurity evaluations aligned with IEC 62443 to identify risks, strengthen defenses, and enhance operational resilience across turbomachinery and automation systems.

  • Risk Assessment (IEC 62443): Threat modeling, zone/conduit analysis, and risk prioritization

  • Vulnerability Assessment: Identification of misconfigurations, outdated systems, and exposure points

  • Security Level Identification: Determination of current and target security levels (SL-C / SL-T)

  • Maturity Level Identification: Evaluation of governance, monitoring, incident response, and lifecycle readiness

  • Penetration Testing: Controlled validation of security controls under simulated attack scenarios

Cybersecurity Design

FOX engineers secure-by-design industrial cybersecurity frameworks tailored for turbomachinery, automation systems, and OT environments — integrating governance, compliance, and resilient network architecture from the ground up.

  • Creation & Implementation of Security Policies & Procedures: Development of OT-aligned policies covering access control, remote access, change management, incident response, and compliance with IEC 62443, ISO 27001, and NIST standards.

  • Network Architecture Design: Secure OT/IT segmentation, zone & conduit modeling, DMZ implementation, and standards-based architecture design to protect critical control systems while maintaining operational reliability.

Cybersecurity Maintenance

Cybersecurity is an ongoing lifecycle process. FOX provides structured maintenance services to ensure industrial automation and turbomachinery systems remain protected against evolving threats while maintaining operational continuity.

  • Periodic System Verification: Routine reviews to identify new vulnerabilities, validate security controls, and apply critical updates aligned with emerging threat intelligence.

  • OS & Antivirus Updates (HMI / Historian): Controlled patch management and antivirus updates for HMI, historian, and supporting systems — executed without disrupting operations.

  • Remote Access Security Hardening: Implementation and maintenance of secure remote access controls, including data-diodes, encrypted VPNs, intrusion prevention systems (IPS), and read-only access with user-level authentication.

FOX ensures your OT environment remains secure, compliant, and resilient over the long term.

01 — Network Protection

Network & Infrastructure Protection

Industrial environments require strict separation between business IT systems and control networks. FOX designs secure, segmented architectures that protect critical control systems from external and internal threats.

✅ Segmentation of control and business networks

02 — Secure Access

Secure Remote Access

Remote access is essential for diagnostics, troubleshooting, and performance optimization — but unsecured access is one of the largest cyber risks in industrial facilities. FOX deploys hardened remote access solutions designed for industrial control systems.

✅ Encrypted VPN connections (site-to-site & client)

✅ Multi-Factor Authentication (MFA) for all remote users

✅ Role-based access control (RBAC)

✅ Time-bound session access with auto-expiry

✅ Encrypted communication tunnels
