Operational Technologies & Cybersecurity Support

We focus on practical, engineering-driven cybersecurity that fits how your operations actually run, not just how a policy document is written.

Your control systems are critical—and increasingly connected. CueBid Automation helps utilities, industries, and infrastructure owners secure their Operational Technology (OT): PLCs, RTUs, SCADA, networks, remote access, and field devices.

OT Cybersecurity Services

CueBid Automation provides a range of OT-focused security services, from quick health checks to full architecture design.

1. OT Security Assessments

  • High-level and detailed reviews of SCADA, PLC/RTU, and network architectures

  • Identification of external connections, remote access paths, and “shadow IT” risks in control systems

  • Gap analysis against common OT security best practices (e.g., zoning, segmentation, remote access, backups)

  • Prioritized recommendations that consider both risk and operational reality

2. Network & Architecture Hardening

  • Design and refinement of OT network segments (control LANs, DMZs, and interfaces to IT)

  • Switch, router, and firewall rule recommendations for OT environments

  • Network zoning and conduits for plants, remote sites, and enterprise connections

  • Standard patterns for adding new sites or systems without weakening the overall posture

3. Secure Remote Access

  • Design of VPN and remote access solutions for plants, remote stations, and vendor access

  • Role-based access concepts and least-privilege approaches for OT

  • Procedures for provisioning, changing, and revoking remote access

  • Guidance for logging, monitoring, and auditing remote sessions

4. System Hardening & Asset Protection

  • Basic hardening steps for SCADA servers, HMIs, historian, engineering workstations, and PLC/RTU programming laptops

  • Guidance on patching/upgrade strategies that respect uptime requirements

  • Backup and restore strategies for SCADA configurations, PLC/RTU logic, and HMI projects

  • Improved password/credential handling for OT systems and devices

5. Policies, Procedures & Training

  • Practical OT procedures for:

    • Remote access

    • Change management (logic changes, configuration changes)

    • Backup/restore

    • Vendor access and field service support

  • Awareness sessions for operators, maintenance staff, and engineers (how security issues show up in daily work)

  • Collaboration with IT to align OT practices with corporate security policies

6. Incident & Recovery Preparedness

  • High-level incident response runbooks tailored for OT environments

  • Guidance on what to log, where to log it, and who reviews it

  • Playbooks for restoring control systems from known-good baselines after an incident

  • Integration of OT-specific considerations into broader corporate incident response plans

Working With Your IT & Security Teams

OT security cannot live in a silo. We work alongside your IT and security teams:

  • Translate plant and operations requirements into network and security design constraints

  • Help IT understand which systems are truly “critical” for operations and what can/cannot be interrupted
  • Provide diagrams, asset lists, and context needed for broader enterprise security efforts
  • Support alignment with corporate standards while maintaining safe and reliable operations

Traditional IT security focuses on confidentiality and data. In OT, the priorities are:

  • Safety – People and environment

  • Reliability & uptime – Pumps, valves, breakers, and processes must keep working

  • Integrity of control – Commands must be trustworthy and predictable

That means security controls in OT must be designed so they do not break operations—and they must be understood by operators, maintenance staff, and IT alike.

Why CueBid Automation for OT & Cybersecurity?

  • OT-first mindset – We understand pumps, valves, PLCs, and SCADA screens—not just ports and protocols.

  • Vendor-neutral – We design security measures around your existing platforms and constraints.

  • Integrated with controls – Security decisions are aligned with control logic, HMI, and telemetry designs, not bolted on afterward.

  • Practical and phased – We focus on achievable steps and phased roadmaps instead of all-or-nothing redesigns.
