A global automotive spare parts manufacturer operating across 18 sites faced the challenge of securing diverse operational technology (OT) environments, including legacy industrial control systems (ICS). The customer needed continuous monitoring, anomaly detection, improved threat visibility, and stronger readiness for compliance assessments and third-party audits. This required a risk-prioritized cybersecurity roadmap to classify assets by criticality, assess security gaps against IEC 62443 standards, and enable phased remediation across its manufacturing landscape without compromising operational security.

OT/ICS Security
A global automotive spare parts manufacturer operated across 18 sites, with diverse technologies and legacy operational technology (OT) environments. Identifying and mitigating cyber risks across these interconnected manufacturing operations required a structured, risk-based approach.
The customer needed continuous monitoring and anomaly detection across OT networks, improved visibility into abnormal network behaviour, and readiness for compliance assessments and third-party audits. A strategically phased cybersecurity roadmap was essential to prioritize remediation based on asset criticality, threat exposure, and potential consequences.
Bosch SDS adopted a risk-based approach to OT/ICS cybersecurity, combining security maturity assessments, asset classification, real-time threat detection, and secure configuration practices. The engagement focused on addressing critical vulnerabilities, improving visibility across OT networks, and establishing a structured roadmap aligned with IEC 62443 standards.
The engagement delivered measurable improvements in OT cybersecurity while establishing a more structured approach to risk management across manufacturing operations.
90% high-risk vulnerabilities mitigated within three months
100% external exposure eliminated in the OT layer
Risk-based remediation guided by asset criticality and threat exposure
Real-time threat visibility through protocol-aware intrusion detection
IEC 62443 compliance framework with mapped controls and audit evidence
Bosch SDS combined OT cybersecurity expertise with a structured, risk-based approach to securing complex manufacturing environments. By aligning security assessments, asset classification, threat detection, and remediation with IEC 62443 standards, the engagement addressed critical vulnerabilities while strengthening visibility across the OT landscape.
The results demonstrate the value of a targeted, standards-aligned approach: 90% of identified high-risk OT vulnerabilities mitigated within three months and 100% of external exposure eliminated in the OT layer. With mapped compliance controls and audit evidence in place, the customer gained a stronger foundation for operational resilience, ongoing risk management, and compliance readiness across its manufacturing operations.
