GDPR · Art. 28

Data Processing & DPA

As soon as a service provider processes personal data on your behalf – cloud, newsletter tool, payroll – Art. 28 GDPR requires a Data Processing Agreement (DPA). SimpleAct manages all DPAs, evidence and sub-processors centrally.

What is a DPA?

A Data Processing Agreement (DPA) governs the processing of personal data by a service provider (processor) on behalf of and under the instructions of the controller. It is mandatory under Art. 28 GDPR as soon as an external provider has access to personal data. Without a valid DPA, sharing data with the provider is unlawful – no matter how secure the provider is.

Mandatory contents of a DPA

Subject & instructions
Nature, purpose and duration of processing, plus binding to the controller’s documented instructions.
Confidentiality & security
Obligation to confidentiality and to technical and organisational measures under Art. 32.
Sub-processors
Rules for engaging further providers – including authorisation and flow-down of obligations.
Deletion & return
Duty to delete or return data after the service ends, plus support for data subject rights.

Manage DPAs compliantly

  • Identify all providers with data access
  • Conclude a DPA under Art. 28 with each provider
  • Record and authorise sub-processors
  • Obtain the processor’s evidence of security measures
  • Check third-country transfers in the DPA (SCC needed?)
  • Link DPAs to the records of processing
  • Version contracts and keep deadlines in view

Frequently asked questions about data processing

When do I need a DPA?

Whenever an external provider processes personal data on your behalf – e.g. hosting, email marketing, CRM, accounting or support tools.

Is a DPA the same as sharing data with third parties?

No. In processing, the provider acts on your instructions. Transferring data to an independent controller follows different rules and needs its own legal basis.

Who is liable for a breach by the provider?

The controller generally remains responsible. The processor is jointly liable if it breaches specific obligations or the instructions.

Is the provider’s standard DPA enough?

Often yes – but it must cover all mandatory contents of Art. 28 and match your actual usage. Check sub-processors and third-country transfers in particular.
