Operational Continuity Assured

Every Minute of Downtime Costs.

Safeguarding your physical industrial assets with 24/7 monitoring and actionable insights.

Cyber threats to operational environments are escalating.

These numbers are already inside your plant!

Tip of the Ice Berg

Why Traditional IT Security
Only Sees the Tip of Your Risk

We secure what's below the surface,
where your physical operations live.
without risking disruption.

What you can't see in your
operations could be the biggest threat to your business.

Level 1

Enterprise IT Systems

The traditional Information Technology (IT) environment uses
centralised, on-premises systems to support core business functions
such as communication, data management, and business applications
for email, planning, and logistics.

These systems are closely monitored, maintained, and updated to
ensure operational continuity.

Level 2

Physical Security &
Site Access Systems

These systems manage physical access to buildings and sensitive
areas through doors, badge readers and security cameras.

They are essential for protecting staff, assets and operations but
responsibility is often split across facilities and security teams.

If compromised, they can allow unauthorised access, creating risk to
both people and critical systems.

THE SHALLOWS Where Physical Meets Digital DANGER LEVEL

Level 3

Building Management
Systems (BMS)

BMS control the environment inside buildings, including heating,
ventilation, air conditioning, and lighting. They ensure operational
stability, safety, and compliance, but are rarely monitored or secured by
IT teams.

Disruption can halt operations, damage equipment, or create health
and regulatory issues.

THE MIDDLE Unseen and unprotected DANGER LEVEL

Level 4

Utilities & Infrastructure
Systems

These systems provide essential services such as power, water and
waste handling across the site. They are critical for operational
continuity but are typically not monitored like IT systems.

Failures or compromise can cause production shutdowns,
environmental damage, and significant financial impact.

Level 5

Industrial & Automated Control
Devices

These devices control critical machinery, robotics, and automation that
power production.

They cannot be easily patched or taken offline, leaving persistent
vulnerabilities in place. If compromised, they directly threaten safety,
halt production and disrupt the supply chain, causing operational and
financial losses.

How we protect OT Environments

Asset Management & Visibility

Know what exists before you can protect it

We establish complete visibility across your OT environment, identifying and classifying connected devices, systems, and communications without disrupting operations. This creates an accurate, real-time inventory of assets that are often unmanaged or undocumented.

Vulnerability & Risk Assessment

Understand exposure and operational impact

We assess device vulnerabilities and environmental risks within the context of OT operations, aligned to IEC 62443 framework for industrial control systems and ISO 27001 for information security risk management. This includes identifying insecure configurations, legacy systems, and potential attack paths, while prioritising risks based on operational, safety, and business impact.

Monitoring & Threat Detection

Detect threats before they become incidents

We provide continuous monitoring and OT-aware threat detection to deliver real-time visibility into network communications across your OT environment. By correlating data from devices, networks, and control systems, we identify anomalous behaviour, unauthorized changes, policy violations, and early indicators of compromise—enabling timely response while maintaining operational continuity and without interfering with real-time processes.

OT Security Operations Center (SOC) & Incident Response

Respond decisively to protect safety and continuity

Our OT-dedicated Security Operations Center provides 24/7 oversight of industrial environments, ensuring threats to operational technology are detected and escalated without delay. In the event of a security incident, our OT-focused response team delivers rapid containment, forensic analysis, and remediation, guided by pre-defined playbooks and validated through tabletop exercises. This approach minimizes operational disruption, safeguards critical assets, and ensures alignment with relevant compliance and regulatory requirements.

Every minute of downtime costs!

Is your OT environment protected?

Most operational environments aren’t protected and downtime is costly. Resilium strengthens your operational environment from the ground up, combining asset security with real-time threat detection and rapid response keeping your critical infrastructure protected.
