Data Processing Agreement

A Data Processing Agreement (DPA) is a contract between a data controller and a data processor that governs how the processor handles personal data on the controller’s behalf. It typically supports compliance with privacy and data protection laws by defining the scope, purpose, and conditions of the processing activities.

Key elements

While exact requirements differ by jurisdiction and regulation, a DPA commonly:

• Identifies the roles of the parties (controller, processor, and any sub-processors).
• Describes the categories of personal data and data subjects involved.
• Defines the purposes and duration of the processing.
• Specifies technical and organizational measures to protect personal data.
• Addresses data breach notification procedures and timelines.
• Sets conditions for using sub-processors and for international data transfers.
• Describes support for data subject rights requests where applicable.
• Outlines rules for returning or deleting data at the end of the engagement.

Use in industrial and manufacturing environments

In industrial operations and regulated manufacturing, a DPA commonly applies when:

• A cloud or hosting provider stores MES, ERP, laboratory, or quality data that includes personal data about employees, operators, or customers.
• An external analytics or IIoT platform processes machine, batch, and event logs that are linked to identifiable personnel.
• A third party provides support services (for example, remote maintenance of OT systems) with access to logs or tickets containing personal information.

In these settings, the DPA complements master service agreements and data security schedules. It focuses specifically on how personal data is processed, separate from general cybersecurity or operational controls for production systems.

What a Data Processing Agreement is not

• It is not a general non-disclosure agreement, although it may reference confidentiality.
• It is not a complete information security policy for OT or IT systems, but it may reference required security controls.
• It is not a product specification or system design document for MES, ERP, or plant systems.

Common confusion

• DPA vs. Data Sharing Agreement: A DPA regulates processing on behalf of a controller, while a data sharing agreement often covers data exchange between independent parties determining their own purposes.
• DPA vs. Master Service Agreement (MSA): An MSA covers overall commercial and service terms; the DPA focuses on processing of personal data within that relationship.
• DPA vs. Security Addendum: A security addendum sets technical and security requirements for systems and services; a DPA sets legal and procedural rules for personal data processing and may reference the security addendum.

Operational implications

For OT/IT, MES, and quality system stakeholders, a DPA often drives:

• Requirements on logging, access control, and data retention for personal data in production and quality systems.
• Documentation of data flows from plant systems to external service providers or cloud platforms.
• Procedures for breach detection, notification, and incident response where personal data is involved.

These operational controls are usually implemented through internal policies, system configurations, and vendor management processes that align with the commitments made in the DPA.
