OT Cyber Security for Industrial Environments
Protect production without disruption.
Secure Operational Technology (OT) Without Disrupting Production
Improved OT visibility, including assets, connectivity, and high-risk pathways
Prioritise risks, with a focus on safety, availability, and realistic exploit paths
Align IT and OT to speed up improvements and reduce friction
Gain a clear improvement roadmap that follows industry best practices, including IEC/ISO 62443
Industrial environments run on availability and safety. But legacy systems, visibility gaps, and expanding connectivity have made OT a high-value target for cybercriminals.
With our OT Security Assessment for ICS environments, companies gain a clear baseline of risk and practical priorities for improvement.
What is Northwave’s Approach to OT Security?
OT security succeeds when it’s production-safe and works across IT and OT.
We first help organisations gain visibility, then implement a structured path to improvement.
1. Visibility first
2. Attention to unique OT challenges
3. Structured outcomes
4. Standards alignment where it matters
5. Bridge IT and OT
6. Ensure business continuity
What Are the Main Threats to OT Security?
OT environments face distinct threats, especially when remote access, suppliers, and IT connections expand the attack surface.
- IT incidents escalating into operational disruption
- Nation-state and geopolitical threats to critical sectors
- Vulnerabilities in remote access and supply-chain connectivity
- Missing segmentation between IT and OT
- ICS-specific malware and emerging AI-driven attacks
Northwave’s Cyber Threat Intelligence closely monitors threats to OT security in Europe. Our free Global Threat Landscape Report details how a crossover between nation-state threat actors and cybercriminals are increasing risks in the manufacturing sector and what you can do about it.

Turn Recommendations into Defence
OT security doesn’t improve by report alone. Your teams need help translating priorities into changes that are safe and operationally realistic. Take the next, practical steps with the support of Northwave’s OT Security Consultancy.
We guide organisations through:
- Segmentation and hardening to stop attackers from using IT to access OT environments
- Remote access risk reduction and supplier connection governance
- Practical remediation planning that fits maintenance windows and production needs
- Bridging IT/OT decision-making, reducing delays and misalignment

OT Security FAQs
1. Is OT security the same as IT security?
No. OT environments prioritise availability and safety, often rely on legacy systems/protocols, and operate under strict production constraints.
2. Will an assessment disrupt production?
The assessment is designed around a non-negotiable principle: production must not be disrupted.
3. Do you align to IEC/ISO 62443?
4. What happens after the assessment?
5. What's driving OT Risk in Europe?
Many organisations are managing OT with outdated protocols, technical debt, limited monitoring, and a shortage of OT security skills. Meanwhile, attackers increasingly pivot from IT into OT, and regulatory demands are rising.
Common OT security challenges we see:
- Production pressure limits downtime for patching and change windows
- Legacy systems and protocols weren’t designed with cyber security in mind
- Visibility gaps prevent good oversight of asset ownership and network paths
- Skills shortage and talent scarcity keep teams running at capacity
- Regulatory pressure is rising as OT is in scope for NIS2 and the Cyber Resilience Act
- Siloed IT and OT creates governance and decision-making bottlenecks
