Operational Technology (OT) Services ICS & IoT

Operational Technology environments are engineered systems designed to deliver physical outcomes under strict constraints of safety availability and process stability.

Unlike enterprise IT ICS and industrial control environments operate with deterministic behavior real time response requirements and tightly coupled dependencies between hardware software networks and physical processes.

In these environments failure has direct physical and operational consequences.

Production downtime safety incidents and loss of process control are often the result of poorly governed change undocumented dependencies or uncontrolled access rather than isolated cyber events.

Many industrial and facility environments rely on legacy controllers proprietary protocols constrained maintenance windows and asset lifecycles that extend well beyond vendor support policies. Securing such systems requires approaches that respect process integrity operational limits and the risks introduced by intervention.

BMO approaches OT security and resilience as an engineering discipline.

By establishing visibility controlled access governance and resilience measures aligned with operational constraints we secure ICS and IoT environments without compromising safety uptime or process stability while supporting alignment with frameworks such as NIS2 and IEC 62443.

(OT) Network & Asset Visibility

What it solves:

Using purpose-built OT visibility platforms such as Nozomi Networks Claroty and Dragos, together with rugged network security appliances from Fortinet Cisco Moxa ABB Honeywell or Hirschmann organizations can uncover hidden assets, unmanaged devices, and insecure communication paths in their production environments and eliminate limited visibility across industrial control networks and legacy systems.

Deliverables:

Comprehensive, automatically generated asset inventory of all OT and ICS endpoints, including PLCs, HMIs, and sensors.
Detailed network topology mapping and protocol-level traffic analysis (Modbus, DNP3, IEC 104, PROFINET, etc.).
Risk classification per device, zone, and communication flow, integrated with SIEM or SOC dashboards.

Results:

Unified visibility across IT and OT domains, creating a verifiable security baseline for continuous monitoring. Operations and cybersecurity teams gain full awareness of critical assets, detect anomalies early, and maintain compliance with frameworks such as ISA/IEC 62443 and NIST CSF strengthening both uptime and safety.

ICS Security Assessment & Hardening

What it solves:

Legacy industrial control systems often operate with outdated firmware, weak segmentation, and default configurations that make them vulnerable to cyber and physical threats. Leveraging solutions from TXOne Networks, Palo Alto Networks Fortinet Check Point Rugged, and Siemens SCALANCE S, organizations can assess vulnerabilities in PLCs HMIs and SCADA networks while enforcing defense-in-depth policies aligned with modern industrial security standards.

Deliverables:

Comprehensive vulnerability and configuration assessment of ICS components including firmware, access control, and communication protocols.
Zoning and segmentation design following ISA/IEC 62443 and NIST SP 800-82 frameworks, supported by rugged firewalls and secure gateways.
Detailed hardening roadmap with prioritized actions for patching, configuration control, and secure remote access.

Results:

A hardened and resilient control environment that minimizes exposure to ransomware and targeted OT attacks. Secure network architecture enables controlled communication between production and corporate zones, ensuring operational continuity safety and regulatory compliance across industrial processes.

IoT Device & Edge Security Governance

What it solves:

The rapid expansion of connected IoT and edge devices introduces unmanaged endpoints, weak authentication, and inconsistent firmware control that create new attack surfaces. By integrating visibility and policy enforcement tools from Armis, Tenable OT Security (Indegy) Cisco IoT Security Microsoft Defender for IoT and Palo Alto IoT Security organizations can secure device onboarding monitor behavioral anomalies, and align IoT assets with enterprise security frameworks.

Deliverables:

Discovery and classification of all IoT and edge assets across production facilities, and remote sites.
Security governance framework for identity management, firmware integrity and lifecycle control.
Integration of IoT telemetry and alerts into centralized SIEM/SOC platforms for unified monitoring and response.

Results:

A consistent and enforceable security posture across IoT and edge ecosystems. Organizations achieve trusted connectivity from device to cloud, protect data integrity at every layer, and enable safe digital transformation while maintaining compliance with international cybersecurity standards.

Operational continuity and safety in industrial and OT environments require more than monitoring alone. They depend on engineered control governed access and resilience designed into systems that support production facilities and critical operations.

This solution integrates with BMO Security Operations and Managed SOC services where continuous monitoring and incident response are required ensuring that detection and response are grounded in well governed OT architectures with clearly defined zones conduits and operational priorities.

Where upgrades or protective controls are required BMO designs supplies and implements the necessary industrial security equipment including rugged network segmentation components secure remote access solutions OT visibility platforms and supporting infrastructure delivering accountable implementation from design to commissioning.

The solution is aligned with applicable regulatory and standards frameworks including NIS2 requirements for essential and important entities as well as industrial cybersecurity standards such as IEC 62443. Where applicable implementation scope documentation and controls are structured to support evaluation under national and EU funding and subsidy programs focused on industrial cybersecurity resilience critical infrastructure protection and operational continuity subject to eligibility and approval.

Can this solution be supported by national or EU funding programs?

Yes. The solution scope technical documentation and implemented controls are structured to support evaluation under national and EU funding programs addressing industrial cybersecurity resilience critical infrastructure protection and operational continuity.

Eligibility and approval depend on the applicable program requirements and the assessment of the responsible authorities.
