Operational technology (OT) security
What if a cyberattack were to paralyze your plant, causing financial losses, operational disruption and negatively impacting your reputation?
Operational technology, including equipment, devices and systems, are at the heart of critical industries. And yet, its security is often put on the back burner. At VARS, we understand the specific challenges of these complex systems.
That’s why we offer tailored solutions to protect your operations, ensure production continuity and improve the efficiency and reliability of your infrastructure.
Our expertise is recognized in a wide range of sectors

A favourable environment for threats
Main influencing factors
- Digital convergence: Integrating IT and OT systems increases the attack surface.
- Lack of specialized resources: Over 50% of OT security professionals have less than five years of experience.
- Geopolitical conflicts: Approximately 60% of OT/ICS incidents are blamed on foreign state-affiliated groups.
The conclusion is clear: threats are rapidly increasing, and your organization is on the front line.
Intelligent monitoring and advanced detection for your OT environments
OT-specific expertise, protection that’s both passive and intelligent
At VARS, we understand that operational technology (OT) requires expertise that is distinct from that of IT systems. That’s why we have developed solutions specifically designed for critical industrial environments. Our monitoring systems are both passive and intelligent, ensuring that they will never interfere with your factory equipment, while providing advanced threat detection for optimal security.
Around-the-clock protection for your operational technology
24/7 emergency response by OT specialists
Benefit from specialized protection using high-performance tools designed to monitor, detect and remediate any threat to your critical OT systems.
Our team of OT cybersecurity experts, available 24/7, acts as an extension of your first line of defence. In the event of an incident, we assess the situation, identify its impacts and immediately implement the necessary measures to minimize risk. Our OT experts use specialized tools to ensure proactive monitoring and ultrafast response.
Direct consequences of attacks on OT systems
- Unexpected production stoppages
- Deterioration in product quality
- Supply chain disruptions
- Loss of trust among customers and partners
- Growing customer dissatisfaction
- Long-term strategic ramifications
- Risk of regulatory sanctions
- Potential legal action
- Damage to brand image and loss of market value
- Environmental risk
- On-site injuries
- Serious physical consequences
Our strategic priorities for your security
Operational technology security plays a key role in the efficiency, reliability and resilience of your operations. This requires a proactive and targeted approach to reduce risk and ensure business continuity.
At VARS, our team has identified five strategic priorities to enhance your security posture.
Have a robust action plan in place to protect system integrity and ensure rapid recovery in the event of an incident.
Design robust systems that integrate security principles, such as segmentation, industrial demilitarized zones (IDMZs) and increased visibility.
Implement a continuous monitoring solution to detect threats in their early stages.
Apply rigorous controls, such as multifactor authentication, to protect your critical environments.
Regularly assess your systems to implement optimal and appropriate security measures.
The figures speak for themselves: we face a growing threat.
The conclusion is clear: threats are rapidly increasing, and your organization is on the front line.
-
+87%
increase in ransomware attacks targeting industrial organizations compared to 2023.
-
69%
of the attacks analyzed targeted the manufacturing sector, with 25% resulting in a total shutdown of production among the 1,171 attacks recorded.
-
+50%
growth in groups of malicious actors targeting OTs, 50% of which are focusing their attacks on the manufacturing sector exclusively.
FAQs
Protecting your OT requires robust and adapted solutions. At VARS, we recommend a comprehensive approach: strict access control, advanced intrusion detection and prevention tools (IDS/IPS), specialized firewalls and real-time monitoring.
Operational technology (OT) is at the heart of critical infrastructure, such as factories, power grids and transport systems. A cyberattack on any of these systems can cause major disruptions, financial losses and impacts on public safety. OT security is therefore vital to ensure business continuity and protect critical assets.
OT is exposed to several types of threats, including:
- Ransomware, which can paralyze systems.
- Unauthorized access, often due to weaknesses in security protocols.
- Third-party (suppliers or partners, for example) compromise.
- Human error, which remains one of the main causes of vulnerability.
IT security protects digital data and networks, whereas OT security focuses on availability and integrity of physical equipment.
Regular risk assessment, network segmentation, priority updates and rigorous policies. VARS offers tailored solutions to strengthen your defences.
