OT Cyber Security for Industrial Environments


Protect production without disruption.

OT-SEcurity-1

Secure 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

Establish what exists, how it connects, and where exposure concentrates.

2. Attention to unique OT challenges

Availability and safety priorities, legacy realities, and constrained change windows.

 

3. Structured outcomes

Baseline, prioritised remediation, and a pragmatic roadmap.

 

4. Standards alignment where it matters

Use IEC/ISO 62443 to support compliance-led decisions.

 

5. Bridge IT and OT

Reduce friction and enable faster, safer decision-making.

 


 

6. Ensure business continuity

OT security succeeds when it’s production-safe and works across IT and OT.

 


 

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.

Get a Clear View of Your OT Risks

You can’t protect what you don’t see. Our OT security assessment for ICS environments creates a clear security baseline and prioritised roadmap for improvement. Most importantly, it’s designed to reduce risk without disrupting production lines. Your teams can implement improvements in real operational conditions.

What you gain:

  • Improved OT visibility that includes assets, connectivity, and high-risk pathways
  • Prioritised risk view focused on safety, availability, and realistic exploit paths
  • Pragmatic remediation guidance that respects OT constraints and change windows
  • Clear, achievable roadmap aligned to recognised practices, including IEC/ISO 62443
  • Shared alignment between IT and OT stakeholders to speed up improvements and reduce friction

 
Start with visibility. Book an OT Security Assessment to establish your baseline and define the safest next steps.

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?
Where relevant, we reference IEC/ISO 62443 concepts to support standards-driven, compliance-led decision-making and structured outcomes.

 

4. What happens after the assessment?
You receive a prioritised remediation path and a pragmatic roadmap. Our consultancy can support implementation in an incremental, operationally realistic way.
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
