Sub-processors are third-party companies that handle data on behalf of another company. In the case of Dast, these sub-processors form the backbone of operations—providers for hosting, analytics, communication, and infrastructure. Each one plays a role in delivering the service, but each one also becomes part of the responsibility chain for data protection and compliance.
Understanding Dast sub-processors means looking beyond the brand and into the vendors that enable it. These services can include cloud providers like AWS, security monitoring tools, logging solutions, and support platforms. They are necessary for scaling, reliability, and security, but they also increase the surface area for risk. The more sub-processors in the list, the more privacy policies, compliance checks, and data transfer rules you must track.
Managing sub-processors is not optional for compliance-heavy environments. Regulations like GDPR require clear disclosure of them, along with customer notification for changes. Security-conscious companies review each sub-processor’s certifications, data-handling processes, and breach history before approving them. And because technology stacks evolve quickly, the processor list is never static—it shifts as tools change.
