Laguna Technopark is home to over 270 locator companies, the majority of them Japanese-owned manufacturers in automotive parts and electronics assembly. Honda, Isuzu, Toshiba, Hitachi, Fujitsu, Futaba, Shin-Etsu, and dozens of their Tier 1 and Tier 2 suppliers operate production lines here, all of them connected to the same global supply chains now under increasing pressure to demonstrate OT cybersecurity compliance.

ISA/IEC 62443 is the international standard for securing industrial automation and control systems (IACS). It covers the people, processes, and technology protecting the programmable logic controllers, SCADA networks, distributed control systems, and manufacturing execution systems that run automotive and electronics production in the 471-hectare estate spanning Binan City and Santa Rosa City.

Global Quality Services provides ISA/IEC 62443 certification services for manufacturers and system integrators in Laguna Technopark. We assess your current OT security posture, identify gaps against the applicable standard parts, and build a certified industrial cybersecurity framework that meets the supply chain and regulatory expectations your buyers are already placing on you.

Why Laguna Technopark Manufacturers Need ISA/IEC 62443 Certification

The push for OT cybersecurity in Laguna Technopark is not coming from Philippine regulators first. It is coming from the Japanese and American original equipment manufacturers at the top of the supply chains these locators supply into.

  • Japanese automotive OEM supply chain requirements. Japanese automakers have begun rolling IEC 62443 compliance requirements into Tier 1 and Tier 2 supplier qualification frameworks. A Laguna Technopark supplier producing rocker arm assemblies, wiring harnesses, or automotive stamped parts for a Japanese OEM is now being asked to demonstrate that its production control systems are protected to a defined security level, not just that its finished parts meet dimensional tolerances.
  • Electronics sector qualification. Electronics manufacturers in Laguna Technopark supplying into hard disk drives, computer peripherals, and consumer electronics production chains face similar expectations from buyers in Japan, the US, and Europe who are under their own supply chain cybersecurity obligations.
  • IT/OT convergence on the production floor. Automotive and electronics manufacturers in Laguna Technopark have been adding manufacturing execution systems, IoT sensors, remote monitoring dashboards, and ERP connections to production lines that were originally designed as isolated OT environments. Every one of those connections between an older OT environment and a new IT layer is a potential attack surface that IEC 62443’s zones-and-conduits model is specifically designed to assess and control.
  • PEZA and regulatory context. PEZA registered locators in Laguna Technopark are export-oriented manufacturers whose operational continuity directly affects their PEZA registration standing. A successful cyberattack on a production control system that halts output is a regulatory and commercial problem simultaneously.

What ISA/IEC 62443 Covers

The standard is a series of 14 documents organized into four parts.

  • Part 1: General. Establishes the vocabulary, concepts, and zones-and-conduits security model used throughout the series, along with the Security Level framework for defining protection requirements.
  • Part 2: Policies and Procedures. Defines how asset owners must build an IACS cybersecurity management program, covering patch management, supplier security requirements, and ongoing monitoring.
  • Part 3: System. Covers security risk assessment methodology and the system-level security requirements a deployed control system must meet against its target Security Level.
  • Part 4: Component. Defines technical security requirements for individual IACS components and secure product development lifecycle requirements for component suppliers.

For a Laguna Technopark automotive or electronics manufacturer, the most immediately relevant parts are typically Part 2-1 for building a cybersecurity management program, Part 3-2 for a structured security risk assessment, and Part 3-3 for verifying system security requirements against target Security Levels.

Who ISA/IEC 62443 Applies to in Laguna Technopark

Asset Owners

Asset owners are the manufacturers running production facilities in the park. They are responsible for establishing an IACS cybersecurity management program, conducting security risk assessments across their control system zones and conduits, and defining target Security Levels for each zone based on operational risk profile and buyer requirements.

System Integrators

System integrators design, install, and commission the control system solutions that run production in Laguna Technopark. This includes the automation contractors responsible for PLC programming, SCADA configuration, and MES integration for the park’s manufacturers. IEC 62443 Part 2-4 sets out the cybersecurity requirements that asset owners are entitled to place on their integrators.

Product Suppliers

Product suppliers develop and sell the IACS components, controllers, sensors, drives, switches, and industrial software that run Laguna Technopark production lines. Part 4-1 and Part 4-2 define secure development lifecycle and technical security requirements for these components, and ISASecure third-party certification provides independent verification that a product meets the applicable requirements.

Security Levels in an Automotive and Electronics Context

Security Level requirements in Laguna Technopark vary by production zone and the criticality of the process it controls.

  • Security Level 1. Protection against casual or unintentional violations. Appropriate for low-criticality support zones such as facility management networks or non-production administrative systems.
  • Security Level 2. Protection against intentional violation using simple means with low resources and generic skills. The level most commonly targeted for general production networks in automotive parts and electronics assembly facilities.
  • Security Level 3. Protection against intentional violation using sophisticated means with moderate resources and IACS-specific skills. Appropriate for higher-criticality control zones in precision component manufacturing, cleanroom environments, or facilities where a production halt causes significant supply chain disruption.
  • Security Level 4. Protection against sophisticated, well-resourced, highly motivated attacks. Reserved for control systems where a breach could cause significant safety, environmental, or operational consequences beyond the facility itself.

Determining the right target Security Level for each zone in your Laguna Technopark facility is the foundation of every IEC 62443 assessment we conduct.

Our ISA/IEC 62443 Certification Process for Laguna Technopark

All assessment work is scoped around your production schedule. No step in our process requires halting a running production line.

Step 1: OT Asset Inventory and Network Mapping. We document your IACS architecture, identify all control system components, and map the zones and conduits that define your production environment’s security boundaries.

Step 2: Security Risk Assessment (Part 3-2). We conduct a structured risk assessment across your defined zones and conduits, identifying threats, vulnerabilities, and consequences specific to your sector, your production process, and your position in the automotive or electronics supply chain. Target Security Levels are determined for each zone based on this assessment.

Step 3: Gap Assessment Against Target Security Levels. Your current technical controls, access management practices, patch management processes, and incident response capabilities are reviewed against Part 2-1 and Part 3-3 requirements. A written gap report documents findings in order of remediation priority.

Step 4: Remediation and Hardening. We work with your engineering and operations teams to close identified gaps, including network segmentation between IT and OT environments, access control improvements, patch management adapted to OT constraints, and incident response protocols that do not require production shutdown to execute.

Step 5: IACS Cybersecurity Management Program Build. Your program documentation is built or updated to meet Part 2-1 requirements, covering policies, procedures, roles, responsibilities, and monitoring activities.

Step 6: Certification Audit Support. We coordinate your third-party certification audit with your chosen accredited body and provide technical support through to certificate issuance.

Benefits of ISA/IEC 62443 Certification for Laguna Technopark Manufacturers

Qualifying for Japanese and American OEM Supply Chains

A certified IACS cybersecurity management program gives your procurement and quality teams documented proof of OT security compliance that satisfies the supplier qualification requirements now coming down from automotive and electronics OEMs at the top of the supply chain.

Protecting Production Continuity

<cite index=”3-1″>Ransomware in OT environments has evolved: today’s OT ransomware actors understand production pain points, and threats to disrupt batch runs, leak proprietary process recipes, or trigger emergency shutdowns have replaced or supplement traditional encryption-based extortion.</cite> A structured IEC 62443 framework reduces the attack surface and strengthens your ability to detect and respond before production is disrupted.

A Framework Built for Manufacturing, Not IT

Standard enterprise cybersecurity tools prioritize confidentiality. Industrial cybersecurity must prioritize availability and process integrity, because a halted production line in Laguna Technopark has real commercial and PEZA compliance consequences. IEC 62443 is built on that priority.

Stronger Supply Chain Security Documentation

A certified program gives your procurement team a documented, standardized framework for placing and verifying cybersecurity requirements on your own equipment suppliers and system integrators.

Integration With ISO 9001 and ISO 14001

IEC 62443 addresses OT cybersecurity. ISO 9001:2026 quality management and ISO 14001:2026 environmental management address quality and environmental performance. Running all three gives a Laguna Technopark manufacturer a unified management system picture that covers the full range of what Japanese OEM buyers and PEZA registration expect.

Frequently Asked Questions

What is ISA/IEC 62443 certification?

ISA/IEC 62443 is the international series of standards for securing industrial automation and control systems. Certification demonstrates that an asset owner’s cybersecurity management program, a system integrator’s processes, or a product supplier’s components meet the security requirements for their defined target Security Level.

Why are Japanese automotive OEMs pushing IEC 62443 requirements down to Philippine suppliers?

Japanese automakers are subject to their own national and industry cybersecurity frameworks that require them to manage cyber risk across their full supply chain, not just within their own facilities. Tier 1 and Tier 2 suppliers in Laguna Technopark are now receiving cybersecurity questionnaires and qualification requirements that reference IEC 62443 because their OEM customers are accountable for supply chain cybersecurity at the top of the chain.

How is IEC 62443 different from ISO 27001?

ISO 27001 covers information security management broadly and is designed primarily for IT environments. IEC 62443 is built specifically for operational technology environments where availability and process integrity must take priority over confidentiality. The two standards are complementary, and many Laguna Technopark manufacturers benefit from holding both.

Does IEC 62443 apply to older production lines that are not connected to IT systems?

Yes. Part 2-1 applies to any facility with industrial automation or control systems regardless of IT connectivity. However, the urgency and complexity of the assessment increases significantly when legacy OT environments are being connected to IT systems, which is the transition underway for many Laguna Technopark manufacturers as they add MES, ERP connectivity, and remote monitoring to existing production lines.

How long does ISA/IEC 62443 certification take for a Laguna Technopark facility?

Most facilities complete certification in six to twelve months, depending on the complexity of the IACS architecture, the number of defined zones and conduits, and the current maturity of OT security controls. Facilities with established ISO 9001 or ISO 27001 management systems typically move faster due to existing documentation and process discipline.
