Determining Your Role under GDPR

GDPR distinguishes between two key roles that determine your responsibilities: the data controller and the data processor. Understanding which role your organization plays is fundamental to implementing the appropriate measures for compliance.

Data Controller vs. Data Processor

The differences between Data Controllers and Data Processors are highlighted below in the table –

AspectData ControllerData Processor
DefinitionAn entity that determines the purposes and means of processing personal data.An entity that processes personal data on behalf of the data controller.
Responsibilities– Determines why and how personal data is processed.
– Ensures processing activities comply with GDPR.
– Responsible for data protection impact assessments.
– Must implement data protection principles effectively.
– Processes data only as instructed by the controller.
– Assists the controller in ensuring processing complies with GDPR.
– Must keep records of processing activities.
– Implements appropriate security measures.
Legal Obligations– Must have a legal basis for data processing.
– Obliged to protect data subjects’ rights.
– Needs to appoint a Data Protection Officer (if required).
– Reports directly to supervisory authorities.
– Not directly responsible for legal bases of processing but must follow the controller’s instructions.
– Required to ensure technical and organizational measures for data security.
– May need to appoint a Data Protection Officer, depending on the processing activities.
Liability– Directly liable for non-compliance with GDPR.
– Must ensure that any processors they use also comply with GDPR.
– Liable for non-compliance with the instructions from the controller or GDPR provisions related to processing security.
Relationship with Data Subjects– Direct interaction, including handling requests for data access, correction, and deletion.
– Must inform data subjects about the processing activities.
– Generally has no direct interaction with data subjects.
– Acts under the controller’s guidance for any requests from data subjects.
Data Controller vs. Data Processor

Understanding these roles is critical because it defines your legal obligations under GDPR. Controllers must implement effective measures to ensure and demonstrate compliance, including data protection policies, data protection impact assessments (DPIA), and relevant documentation on processing activities. Processors, meanwhile, are required to maintain records of personal data and processing activities, implement security measures, and keep data confidential.

  • Data Controller: The entity that determines the purposes and means of processing personal data. If your organization decides why and how personal data is processed, it is a data controller. Controllers are responsible for ensuring their processing activities comply with the GDPR Compliance Checklist, regardless of whether the processing is carried out by the organization itself or a third party.
  • Data Processor: The entity that processes personal data on behalf of the data controller. Processors are usually third parties external to the company of the data controller. While processors are not directly subject to the same breadth of legal obligations as controllers, they must still ensure their processing activities comply with GDPR and the controller’s instructions.

The GDPR mandates that organizations must have a valid lawful basis to process personal data. Understanding these bases is crucial for compliance and for maintaining transparency and trust with data subjects.

Obtaining explicit consent from data subjects before processing their data is one of the most straightforward bases. Consent must be freely given, specific, informed, and unambiguous. It requires a positive opt-in; silence, pre-ticked boxes, or inactivity does not constitute consent. Organizations must also allow data subjects to withdraw consent at any time easily.

If processing is necessary for compliance with a legal obligation to which the controller is subject, this basis applies. It covers obligations under EU or Member State law.

Vital Interests

This basis applies when processing is necessary to protect someone’s life. It’s most relevant in emergency health situations or life-and-death scenarios and cannot be invoked for health data processing under employment contexts.

Public Task

Processing based on public interest or in the exercise of official authority vested in the controller applies here. This basis is typically relevant to public authorities and organizations performing tasks in the public interest or exercising official authority.

Legitimate Interests

Organizations may process data if they have a legitimate interest, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject. The legitimate interests basis requires a careful assessment to ensure that the processing is necessary and that data subject interests do not override the organization’s interests.

Rights of Data Subjects

GDPR strengthens individuals’ rights regarding their data. Organizations must ensure mechanisms are in place to facilitate these rights effectively.

  • Right to Be Informed
  • Right to Access
  • Right to Rectification
  • Right to Erasure (‘Right to be Forgotten’)
  • Right to Restrict Processing
  • Right to Data Portability

Implementing GDPR Principles

The GDPR is built around several key principles that form the foundation of data protection laws in the EU. Adhering to these principles is not just about compliance; it’s about demonstrating a commitment to data privacy and security.

Data Minimization

Organizations must ensure that only personal data that is necessary for each specific purpose of the processing is collected and processed. This means limiting the personal data to what is directly relevant and necessary to accomplish a specified purpose.


Personal data must be accurate and, where necessary, kept up to date. Every reasonable step must be taken to ensure that personal data that is inaccurate, considering the purposes for which they are processed, is erased or rectified without delay.

Storage Limitation

Personal data should be kept in a form that permits identification of data subjects for no longer than is necessary for the purposes for which the personal data are processed. Personal data may be stored for longer periods insofar as the personal data will be processed solely for archiving purposes in the public interest, scientific or historical research purposes, or statistical purposes, subject to the implementation of the appropriate technical and organizational measures required by the GDPR to safeguard the rights and freedoms of the data subject.

Integrity and Confidentiality

Personal data must be processed in a manner that ensures appropriate security, including protection against unauthorized or unlawful processing and accidental loss, destruction, or damage. Using appropriate technical or organizational measures, this principle is closely tied to the concepts of confidentiality and integrity of data.

Technical and Organizational Measures

To comply with GDPR, organizations must implement suitable technical and organizational measures to ensure a level of security appropriate to the risk of the data processing activities. This includes measures to protect against unauthorized access, alteration, disclosure, or destruction of personal data.

Security Best Practices

  • Encryption and Anonymization: Implementing data encryption and anonymization techniques can help protect personal data.
  • Access Control: Ensure that only authorized personnel have access to personal data, based on their roles and responsibilities.
  • Data Backup and Recovery: Establishing regular data backup procedures and recovery plans to respond to data breaches or loss.
  • Network Security: Utilizing firewalls, intrusion detection systems, and anti-malware software to protect against external threats.

Data Protection by Design and by Default

  • Data Protection by Design: Incorporate data protection into the development and operation of IT systems, networked infrastructure, and business practices.
  • Data Protection by Default: Ensure that, by default, only personal data that is necessary for each specific purpose of the processing is processed. This applies to the amount of personal data collected, the extent of their processing, the period of their storage, and their accessibility.

Data Transfers Outside the EU

The GDPR imposes restrictions on the transfer of personal data outside the European Union, to ensure that the level of protection of individuals afforded by the GDPR is not undermined. Organizations must ensure that transfers of personal data to countries outside of the EU/EEA are lawful and secure.

Adequacy Decisions

  • The European Commission can decide if a non-EU country ensures an adequate level of data protection. Transfers to such countries may occur without the need for any further safeguards.

Standard Contractual Clauses (SCCs)

  • In the absence of an adequacy decision, organizations may use Standard Contractual Clauses adopted by the Commission or a supervisory authority to provide adequate safeguards for data protection.

Ongoing Compliance Strategies

Ensuring continuous compliance with the GDPR Compliance Checklist requires a proactive and structured approach h. Organizations must regularly review and update their data protection practices to keep pace with legal, technological, and organizational changes.

Regular GDPR Audits

  • Conducting regular audits of data processing activities helps identify compliance gaps and areas for improvement. Audits should cover all aspects of GDPR, including data handling practices, consent records, data protection impact assessments, and breach response plans.

Employee Training and Awareness

  • Regular training programs for employees can significantly reduce the risk of data breaches and non-compliance. Training should cover the organization’s data protection policies, the importance of the GDPR Compliance Checklist, and the role employees play in ensuring compliance. It’s also crucial to foster a culture of data privacy within the organization.

Engaging with Data Protection Authorities (DPAs)

DPAs are independent public authorities responsible for monitoring the application of data protection regulations within their respective jurisdictions.

Interaction with Data Protection Authorities (DPAs) is a critical aspect of GDPR compliance. These authorities are tasked with enforcing data protection laws, offering guidance to organizations, and protecting individuals’ rights concerning their data.

Engaging with DPAs involves:

Consultation and Notification Procedures

  • Organizations may need to consult with the relevant DPA in certain circumstances, such as when conducting a Data Protection Impact Assessment (DPIA) that indicates high risk. Additionally, organizations must be prepared to notify DPAs of personal data breaches within the stipulated timeframe and provide all necessary information to assist in the investigation.

Compliance and Enforcement

  • DPAs have the authority to investigate complaints, conduct audits, issue warnings, and impose fines for non-compliance. Organizations should establish procedures for responding to inquiries from DPAs and demonstrate their commitment to compliance through transparent and cooperative engagement.

Consultation and Notification Procedures

Organizations are required to engage with DPAs in several scenarios, including but not limited to:

  • Pre-consultation: Before processing that is likely to result in a high risk to the rights and freedoms of individuals, organizations may need to consult with the relevant DPA, especially when a Data Protection Impact Assessment (DPIA) indicates significant risks that cannot be mitigated.
  • Breach notification: GDPR mandates prompt notification to the relevant DPA in the case of a personal data breach, typically within 72 hours of becoming aware of it, unless the breach is unlikely to result in a risk to the rights and freedoms of individuals.
  • Annual reports: Some organizations might be required to submit annual reports or records of processing activities to DPAs, especially those involved in large-scale processing of sensitive data or regular and systematic monitoring of individuals on a large scale.

Compliance and Enforcement

DPAs have a range of powers and responsibilities under the GDPR, including:

  • Investigations: Conducting investigations into compliance, either as part of regular checks or in response to complaints.
  • Audits: Performing audits to assess compliance with the GDPR Compliance Checklist, including examining processes, records, and IT security measures.
  • Guidance: Providing guidance and advice to organizations on GDPR compliance, including best practices and compliance checklists.
  • Fines and sanctions: Imposing fines and other sanctions for non-compliance with GDPR. The severity of penalties depends on the nature, gravity, and duration of the infringement.
