Securing a Leading Manufacturing Enterprise in Asia with MSSP 5D Model

A leading manufacturing enterprise in Asia, specializing in automotive and electronic components, faced a surge in cyber threats as it expanded its operations and connected production lines across multiple factories. With the rise of smart manufacturing and IoT automation, the company’s systems became increasingly exposed to attacks such as ransomware, phishing, and data theft. Frequent disruptions caused by malware infections and unauthorized access attempts highlighted the need for a robust cybersecurity framework that could protect operational technology (OT) and IT environments alike. The client required a comprehensive MSSP 5D Model to ensure 24×7 monitoring, rapid incident response, and awareness across all levels of the organization, while maintaining compliance with ISO 27001 and regional data protection standards.

The enterprise adopted a holistic Managed Security Services Provider (MSSP) framework built around the 5D Model; Discover, Detect, Defend, Disseminate, and Dissect. Each layer provided a focused approach to proactive security, combining technology, people, and processes into a unified defense system.

Discover: Vulnerability Assessment & Penetration Testing (VAPT)

• Conducted full internal and external VAPT across IT, OT, and IoT networks.
• Identified 70+ critical vulnerabilities including outdated firmware and weak credentials.
• Simulated real-world attacks to validate system resilience.
• Provided a detailed remediation roadmap with patch verification.
• Hardened infrastructure by isolating vulnerable systems and enforcing password policies.

Detect: Security Operations Center (SOC)

• Established a 24×7 SOC for centralized visibility across all factory sites.
• Integrated WAZUH SIEM to collect and correlate logs from servers, firewalls, and endpoints.
• Built 120+ correlation rules to detect insider threats and suspicious network behavior.
• Deployed AI-based analytics to reduce false positives by 65%.
• Achieved a Mean Time to Detect (MTTD) under 15 minutes for critical alerts.

Defend: Incident Response (IR)

• Created Incident Response playbooks for ransomware, phishing, and insider threats.
• Deployed forensic tools for evidence collection and root-cause analysis.
• Defined escalation procedures with on-site and SOC-level collaboration.
• Conducted quarterly cyber drills simulating real attack scenarios.
• Reduced Mean Time to Respond (MTTR) from 6 hours to under 45 minutes.

Disseminate – Information Security Awareness (ISA)

• Launched bilingual (English/Thai) awareness training for all departments.
• Conducted phishing simulations and hands-on learning sessions.
• Trained over 1,200 employees within four months.
• Reduced phishing click rate from 36% to 5% in six months.
• Embedded security awareness into onboarding and annual HR evaluations.

Dissect – Threat Intelligence (TI)

• Integrated global and regional threat intelligence feeds into the SOC.
• Correlated data with the MITRE ATT&CK framework for accurate threat mapping.
• Identified and blocked 23 malicious IPs and phishing domains proactively.
• Delivered monthly intelligence reports highlighting ransomware and sectoral threats.
• Enabled predictive defense, shifting from reactive alerts to preemptive action.

The MSSP 5D Model delivered a measurable transformation: Operational Continuity: Avoided estimated downtime losses worth over $1.2 million per year. Brand Trust: Strengthened customer and OEM confidence through improved data integrity. Compliance: Achieved full alignment with ISO 27001, NIST, and PDPA requirements. Culture Shift: Moved from reactive security to a proactive, resilient, and educated workforce. The organization now operates with round-the-clock visibility, predictive intelligence, and faster recovery capability essential for sustaining production reliability and business continuity.

“Implementing the MSSP 5D Model completely transformed our cybersecurity posture. We now have full visibility across all manufacturing sites, faster detection and response to threats, and a workforce that understands its cyber responsibilities. Our production and data are secure, allowing us to focus on innovation and growth without interruption.”
