Legacy systems, fragmented OT visibility and weak segmentation are increasing operational risk across manufacturing environments

WHY THIS “OT CYBERSECURITY CHALLENGES IN MANUFACTURING” CHALLENGE?

OT resilience is now a business continuity priority

Manufacturing leaders must secure aging industrial environments while maintaining uptime, safety and operational efficiency at scale.

Key benefits

From reactive security to operational resilience

Protecting continuity across industrial operations

Visibility into critical OT environments

Identify assets, vulnerabilities and hidden dependencies impacting production continuity and cyber exposure

Risk-driven investment prioritization

Align cybersecurity initiatives with operational impact, production risk and regulatory obligations

Secure integration between IT and OT

Reduce exposure created by interconnected systems, remote access and unmanaged industrial assets

A practical roadmap toward ISA 62443

Translate assessments into phased actions that strengthen resilience without disrupting operations

How NTT DATA helps

01

OT cybersecurity maturity assessments

Evaluate governance, risk, operations and continuity capabilities against ISA 62443 and industry best practices

• ISA/IEC 62443 cybersecurity posture assessments

02

Technical OT compliance assessments

Assess network architecture, device configurations and technical controls across the seven foundational requirements

• Industrial risk analysis aligned to operational continuity

03

Industrial risk analysis aligned to operations

Transform technical vulnerabilities into operational risk scenarios tied to safety, production and business impact

• Defensible OT architecture and secure segmentation

04

Secure OT architecture and segmentation

Design defendable industrial environments with secure zones, conduits, monitoring and controlled remote access

• Continuous monitoring and OT threat visibility

05

Prioritized remediation and implementation

Build phased execution plans focused on governance, visibility, segmentation and incident response capabilities

• Governance, compliance, and operational resilience programs

Greater visibility. Faster detection. Stronger operational continuity

Proven impact

Industrial cybersecurity assessments that turn uncertainty into measurable operational resilience

Results that matter

Real OT cybersecurity outcomes that improve visibility, resilience and operational continuity

Up to 73% ISA 62443 compliance improvement

Findings converted into prioritized action plans

82.7% of OT attacks target manufacturing

OT remains the top target, increasing segmentation needs

100% of OT environments had critical misconfigurations

Assessments revealed hidden risks and unmanaged assets

Higher OT maturity reduced operational disruptions

Better governance and monitoring improved resilience

Shape a more resilient future for industrial operations

Start the strategy that secures continuity
