ICS/OT Product Security
Our Product Security service helps OEM manufacturers build security into industrial products from the design phase. We assess development processes, review product architectures, and prepare organizations for IEC 62443 product certification, covering both the development lifecycle (4-1) and the technical security requirements (4-2).
Securing the Product, Not Just the Network
Network segmentation and monitoring protect the environment around a device. They do not fix hardcoded credentials in firmware, weak authentication on management interfaces, or unsigned update mechanisms inside the product itself. As the EU Cyber Resilience Act and customer security requirements tighten, OEMs must demonstrate that their products meet IEC 62443-4-1 and 4-2.
We work with industrial product manufacturers to assess their development lifecycle against IEC 62443-4-1, review product architectures for design-level vulnerabilities, and build the evidence packages required for formal certification. The goal is a product that earns its security level, not one that simply claims it.

Product Lifecycle Security
Building security into industrial products from requirements through certification
Engagement Methodology
Each phase is designed to deliver measurable progress while respecting the operational constraints of live industrial environments.
Secure Development Lifecycle Assessment
Evaluate the current product development process against IEC 62443-4-1 requirements. Identify gaps in security practices across the full lifecycle including requirements, design, implementation, verification, validation, defect management, and end-of-life.
Product Security Architecture Review
Review the product security architecture including authentication mechanisms, access controls, communication protocols, update mechanisms, key management, and data protection. Identify design-level vulnerabilities and recommend architectural improvements aligned with the target security level.
IEC 62443-4-1 and 4-2 Alignment
Map the product development process and product capabilities against IEC 62443-4-1 (secure development lifecycle) and IEC 62443-4-2 (technical security requirements for IACS components). Produce a detailed gap analysis with specific remediation guidance for each requirement.
Secure Coding and Design Practices
Review source code and design patterns for security weaknesses. Establish secure coding guidelines, input validation practices, cryptographic standards, error handling procedures, and threat modeling practices specific to industrial product development.
Compliance and Certification Readiness
Prepare documentation and evidence packages required for IEC 62443 product certification. Conduct pre-certification assessments, identify remaining gaps, and develop a remediation plan to achieve certification readiness within a defined timeline.
Frequently Asked Questions
IEC 62443-4-1 defines the secure development lifecycle requirements for organizations that develop industrial automation products. It covers security management, specification of security requirements, secure design and implementation, verification and validation, defect management, and patch management. Product manufacturers need it because asset owners increasingly require IEC 62443-4-2 certified products, and 4-2 compliance requires a 4-1 certified development process. Certification demonstrates to buyers that your product was built with security embedded throughout the development lifecycle.
