Data Processor
A data processor is an organization or third party that processes personal data on behalf of a data controller, following documented instructions and required safeguards.
What is a Data Processor?
A data processor is a vendor, service provider, or partner that handles personal data strictly according to the instructions of a data controller. Processors perform activities such as storage, hosting, analytics, support services, and infrastructure management while maintaining contractual and legal obligations to secure the data. Under the General Data Protection Regulation (GDPR), processors must implement appropriate technical and organizational measures, support rights requests, assist with compliance reporting, and notify controllers of incidents without undue delay.
Why Data Processors matter
Data processors enable organizations to outsource operations without compromising security or regulatory compliance. Their practices directly influence vendor risk, oversight obligations, and accountability requirements.
Controllers rely on processors to maintain strong security, adhere to contract terms, limit processing to approved purposes, and escalate incidents promptly. Reliable processor management strengthens governance and reduces exposure across the privacy and security ecosystem.
How Data Processors are used in practice
Organizations commonly use data processors such as cloud hosting platforms, CRM systems, IT support vendors, email service providers, monitoring tools, and marketing technology platforms.
Controllers evaluate processors through vendor assessments, data protection agreements (DPAs), and continuous monitoring to ensure compliance with legal and contractual expectations. Processors also support governance programs by providing audit reports, assisting with DPIAs, and participating in breach response workflows.
