Securing the Future of Critical Infrastructure with Rigorous ISA/IEC 62443 Conformity Assessments  

For Original Equipment Manufacturers (OEMs) and Product Suppliers

The ISASecure certification applies to the development lifecycle processes of suppliers for control system products and the physical components they manufacture. The assessment effort determines whether OEM's and Product Supplies maintain structurally integrated secure engineering practices and whether the resulting software applications, embedded devices, host devices, or network devices align with international ISA/IEC Cybersecurity requirements. 

The ISASecure assessment yields distinct operational advantages for product suppliers by replacing self-attestation with independent, empirical validation. This common, standards-based set of requirements drives component security, thereby simplifying product assurance, reducing post-deployment defect remediation cycles, and fulfilling strict procurement mandates for critical infrastructure supply chains.

As an Industry recognized Certification Body, Palindrome Technologies conducts rigorous conformity assessments to validate that hardware, firmware, and software meet the requirements of the IEC 62443 series towards a recognized certification. Conformity assessment for product suppliers include:

• Security Development Lifecycle Assurance (SDLA): Validates the structural integration of secure engineering processes by evaluating the documented development lifecycle against IEC 62443-4-1.
• Component Security Assurance (CSA): Certifies the fundamental security parameters of components exhibiting the characteristics of a software application, embedded device, host device, or network device against IEC 62443-4-2.  
• IIoT Component Security Assurance (ICSA): Certifies Industrial Internet of Things (IIoT) devices and gateways designed to support direct connection to an untrusted network against specific extensions of IEC 62443-4-2. 

For Asset Owners and Facility Operators

The ISASecure certification applies also to asset owners by validating the integrated control systems and site-specific operational technology (OT) deployed within their facilities. Asset owners define procurement criteria, establish acceptable risk tolerances, and approve the overarching protection concepts for complex Industrial Automation and Control Systems (IACS).

The certification provides an objective, standards-based framework that simplifies procurement and ensures systemic risk mitigation across deployed assets. By explicitly requiring ISASecure certification, asset owners ensure that acquired systems provide necessary security capabilities natively, verifying operational continuity and demonstrating adherence to global critical infrastructure mandates. 

Palindrome conducts assessments of facility-level implementations and integrated subsystems to evaluate operational environments and ensure that the intersection of IT, OT, and telecommunications meets structural security requirements. Asset owner Conformity Assessments include: 

• System Security Assurance (SSA): Evaluates integrated control systems consisting of multiple components, assessing defined security zones against IEC 62443-3-3 capability security level requirements.

• Automation Control System Security Assurance (ACSSA): Evaluates operational technology (OT) assets at the facility level to verify site-specific security management systems, integration procedures, and continuous environmental monitoring against IEC 62443-2-1, 2-4, 3-2, and 3-3 standards.
