Data flows across organizations, borders, and systems at an unprecedented rate. It doesn’t matter if you're a startup sharing customer insights with a marketing partner or a multinational corporation transferring employee records between subsidiaries, understanding how to handle personal data legally is non-negotiable. Two critical frameworks govern this territory: the General Data Protection Regulation (GDPR) and Data Sharing Agreements (DSAs). While GDPR sets the legal foundation for data protection across the European Union, DSAs serve as the contractual mechanisms that make compliant data sharing possible. Yet confusion persists about how these two elements relate, where they overlap, and where they diverge.
This comprehensive guide demystifies both concepts, exploring their relationship, similarities, and key differences. If you're a privacy officer drafting your first data sharing agreement, a business leader evaluating partnership opportunities, or simply someone trying to navigate the complex world of data protection, this article will equip you with the clarity you need.
The General Data Protection Regulation (GDPR) represents one of the most significant pieces of privacy legislation in modern history. Enacted by the European Union in May 2018, GDPR establishes comprehensive rules governing how organizations collect, process, store, and share personal data of individuals within the EU.
GDPR is about empowerment and accountability. It grants individuals unprecedented control over their personal information while imposing strict obligations on organizations that handle this data. The regulation applies to any entity processing EU residents' data, regardless of where that organization is physically located, making it truly global in reach.
The regulation also empowers individuals with rights including access to their data, the right to rectification, erasure (the "right to be forgotten"), data portability, and the right to object to certain types of processing. Non-compliance carries severe consequences. Organizations can face fines up to €20 million or 4% of annual global turnover, whichever is higher. Beyond financial penalties, GDPR violations can damage reputation, erode customer trust, and result in operational disruptions.
A Data Sharing Agreement (DSA) is a legally binding contract between two or more parties that establishes the terms, conditions, and responsibilities for sharing data. While GDPR provides the regulatory framework, DSAs translate those requirements into practical, actionable commitments between specific organizations.
A comprehensive DSA typically addresses:
Scope and purpose: What data will be shared and why? The agreement clearly defines which datasets are covered and the specific purposes for which they can be used.
Roles and responsibilities: Who is the data controller? Who is the processor? What are each party's obligations?
Data protection measures: What security standards must be maintained? How will data be encrypted, stored, and accessed?
Duration and termination: How long will the data sharing arrangement last? What happens to the data when the agreement ends?
Compliance requirements: How will both parties ensure adherence to GDPR and other relevant regulations?
Liability and indemnification: Who bears responsibility if something goes wrong?
Data subject rights: How will individuals' rights under GDPR be honored throughout the data sharing process?
DSAs are essential risk management tools. A well-drafted agreement protects all parties involved, ensures legal compliance, and provides clear procedures for handling issues that may arise.
The relationship between GDPR and Data Sharing Agreements is foundational. GDPR mandates that whenever personal data is shared between organizations, appropriate safeguards must be in place and DSAs serve as one of the primary mechanisms for establishing those safeguards.
GDPR functions as the regulatory bedrock upon which all data sharing activities must be built. It establishes the "what" and "why" of data protection, what constitutes personal data, what rights individuals possess, what obligations organizations bear, and why these protections matter.
The regulation explicitly addresses data sharing scenarios through its provisions on data controllers and processors. When Organization A (the controller) shares personal data with Organization B (the processor) for processing activities, GDPR Article 28 requires a written contract or legal act binding the processor. This is where DSAs enter the picture.
While GDPR provides the rules, DSAs provide the playbook. They take broad regulatory requirements and transform them into specific, enforceable commitments tailored to particular data sharing relationships.
For instance, GDPR requires that personal data be processed securely. A DSA translates this into concrete terms: "The receiving party shall encrypt all shared data using AES-256 encryption, maintain access logs for a minimum of 12 months, and conduct quarterly security audits."
Similarly, GDPR grants individuals the right to access their data. A DSA specifies: "Upon receiving a data subject access request, the receiving party shall provide all requested information to the disclosing party within 15 days to enable compliance with the 30-day GDPR deadline."
The interplay between GDPR and DSAs is symbiotic. GDPR gains practical enforceability through DSAs, while DSAs gain legal legitimacy by aligning with GDPR requirements. Neither is sufficient alone.
Consider international data transfers; one of GDPR's most complex areas. The regulation prohibits transferring personal data outside the EU unless adequate protections exist. Standard Contractual Clauses (SCCs), a form of DSA, provide one approved mechanism for lawful international transfers. The SCCs incorporate GDPR principles into binding contractual terms, enabling data flows while maintaining protection standards.
This dynamic also creates accountability mechanisms. When both parties sign a GDPR-compliant DSA, they create contractual obligations that can be enforced in court, separate from regulatory enforcement. If a data processor breaches security requirements specified in the DSA, the controller can pursue contractual remedies in addition to any regulatory action.
While GDPR and DSAs operate at different levels; one as regulation, the other as contract, they share fundamental objectives and principles. Understanding these commonalities helps organizations build coherent data protection frameworks.
Both GDPR and DSAs exist primarily to protect personal data and the privacy rights of individuals. This shared purpose creates natural alignment. GDPR establishes that data protection is a fundamental right, while DSAs operationalize this principle in specific relationships.
If you're reading through GDPR articles or reviewing a DSA, you'll find consistent themes: data should be handled carefully, individuals should maintain control over their information, and organizations should be transparent about their practices.
GDPR's accountability principle requires organizations to demonstrate compliance through documented policies, procedures, and records. Similarly, DSAs create formal documentation of data sharing arrangements, establishing clear audit trails.
Both frameworks reject "trust us" approaches in favor of "show us" standards. Organizations can't simply claim they protect data properly, they must produce evidence. DSAs serve as crucial documentation demonstrating that data sharing relationships incorporate appropriate safeguards as GDPR requires.
GDPR mandates transparency in how organizations collect and use personal data. Individuals must receive clear, understandable information about data processing activities.
DSAs mirror this transparency requirement by documenting the terms of data sharing arrangements explicitly. While DSAs are contracts between organizations rather than notices to individuals, they support overall transparency by creating clear records of how and why data moves between entities.
Both GDPR and DSAs place significant emphasis on technical and organizational security measures. GDPR Article 32 requires appropriate security measures based on risk assessment, including encryption, pseudonymization, and regular security testing.
Well-crafted DSAs incorporate these requirements, specifying exactly what security measures both parties must implement. The agreement might reference GDPR's security requirements directly or detail specific technical controls, creating contractual obligations that reinforce regulatory mandates.
GDPR grants individuals extensive rights over their personal data; access, rectification, erasure, portability, and objection. DSAs must accommodate these rights, establishing procedures for how parties will cooperate when individuals exercise their rights.
For example, if someone requests deletion of their data from the original controller, the DSA should specify how quickly the processor must also delete that information and how deletion will be verified.
GDPR's principles of data minimization (collect only what's necessary) and purpose limitation (use data only for specified purposes) appear prominently in DSAs. Effective agreements explicitly state what data will be shared, why it's necessary, and how it may be used.
A DSA might specify: "Party B shall receive only customer email addresses and purchase histories for the sole purpose of sending order confirmations. Party B shall not use this data for marketing purposes or share it with third parties."
GDPR carefully regulates international data transfers, recognizing that data protection risks increase when information crosses borders. DSAs for international data sharing must incorporate additional safeguards, such as Standard Contractual Clauses or adequacy assessments.
Both frameworks acknowledge that data protection shouldn't stop at geographical boundaries. Whether through GDPR's transfer restrictions or DSA provisions addressing international data flows, the goal is consistent protection regardless of location.
Despite their complementary relationship, GDPR and DSAs differ fundamentally in nature, scope, and application. Understanding these distinctions is essential for proper implementation.
GDPR: A binding regulation with the force of law across all EU member states. It derives authority from the European Union's legislative process and applies automatically without requiring consent from regulated entities.
DSA: A contractual agreement requiring mutual consent between specific parties. It derives authority from contract law and binds only the signatories.
This difference has profound implications. You can't opt out of GDPR compliance if you process EU residents' data; it applies whether you like it or not. But you can choose whether to enter a particular DSA, and its terms can be negotiated between parties.
GDPR: Applies broadly to any organization processing personal data of EU residents, regardless of the organization's location. Its provisions cover all aspects of data processing, collection, storage, analysis, sharing, and deletion.
DSA: Applies narrowly to specific data sharing arrangements between defined parties. Each DSA covers only the particular data sharing relationship it addresses.
While GDPR establishes baseline requirements affecting millions of organizations globally, each DSA is unique to its parties and circumstances. An organization might comply with GDPR once but require dozens of different DSAs for various data sharing relationships.
GDPR: Relatively inflexible. Its requirements are fixed by law, and organizations must comply with them regardless of their specific circumstances or preferences. While interpretation may vary, the core obligations remain constant.
DSA: Highly flexible and customizable. Parties can negotiate terms, adjust provisions to fit their specific needs, and include additional protections beyond GDPR minimums.
This flexibility makes DSAs practical tools for diverse scenarios; from simple one-time data transfers to complex ongoing collaborations. Parties might establish more stringent requirements than GDPR mandates if their risk tolerance or business needs demand it.
GDPR: Enforced by data protection authorities (supervisory authorities) in each EU member state. These regulators can investigate complaints, conduct audits, and impose administrative fines. Individuals can also bring legal actions under GDPR.
DSA: Enforced through contract law mechanisms. If one party breaches the agreement, the other can pursue contractual remedies including damages, specific performance, or termination. Enforcement typically requires one party to initiate legal action.
A GDPR violation might trigger regulatory investigation and fines even without any party filing a complaint, while DSA breaches typically require one party to actively pursue enforcement through courts or arbitration.
GDPR: Establishes principles and high-level requirements, providing frameworks rather than detailed specifications. For example, GDPR requires "appropriate technical and organizational measures" but doesn't dictate specific encryption algorithms or security protocols.
DSA: Provides detailed, specific terms tailored to particular data sharing arrangements. A DSA might specify: "All data shall be transmitted via SFTP using TLS 1.3 or higher, stored in encrypted databases using AES-256 encryption, and accessed only through multi-factor authenticated connections."
This difference reflects their different purposes, GDPR must apply across countless scenarios, while DSAs address specific situations where precise requirements are both possible and necessary.
GDPR: Ongoing and indefinite. The regulation remains in force until amended or repealed through legislative processes. Organizations must maintain continuous compliance as long as they process relevant personal data.
DSA: Defined duration. Each agreement specifies its term; perhaps one year, five years, or until a specific project concludes. When the DSA expires or terminates, its terms no longer govern the relationship (though obligations regarding previously shared data may continue).
GDPR: Applies based on the location of data subjects (individuals) or the organization's establishment in the EU. An Australian company processing French residents' data must comply with GDPR.
DSA: Governed by whatever jurisdiction the parties specify in the contract. Parties might choose UK law, New York law, or any other jurisdiction to govern their agreement, regardless of where data subjects reside.
This means a DSA between two US companies sharing EU residents' data might be governed by California law for contractual disputes, while still needing to comply with GDPR for data protection requirements.
GDPR: Can interact with other privacy laws, sometimes creating complex compliance scenarios. Organizations might need to comply with GDPR, California's CCPA, Brazil's LGPD, and other regulations simultaneously.
DSA: Must comply with GDPR and other applicable laws but can also address additional requirements beyond legal minimums. A DSA might incorporate industry-specific standards, company policies, or security frameworks that exceed GDPR requirements.
GDPR: Can only be amended through formal EU legislative processes involving the European Parliament and Council. Changes occur infrequently and apply automatically to all covered organizations.
DSA: Can be amended whenever both parties agree, subject to any amendment provisions in the contract itself. Parties can quickly adapt their agreement to changing circumstances, new risks, or lessons learned.
This difference provides DSAs with agility that GDPR lacks, allowing data sharing arrangements to evolve as technology, business models, and risk landscapes change.

Q: Is a Data Sharing Agreement legally required under GDPR?
A: GDPR doesn't explicitly require a document titled "Data Sharing Agreement" in all circumstances. However, Article 28 requires a written contract or legal act when a controller engages a processor. Additionally, joint controllers must arrange their responsibilities through a contract (Article 26). Standard Contractual Clauses serve as DSAs for international transfers. While terminology varies, documented agreements covering GDPR requirements are effectively mandatory for most data sharing scenarios.
Q: Can a DSA override GDPR requirements?
A: No. GDPR represents binding law that cannot be contracted away. A DSA can impose stricter requirements than GDPR mandates, but it cannot reduce protections below GDPR minimums. For example, a DSA might require 24-hour breach notification between parties (stricter than GDPR's 72-hour authority notification requirement), but it cannot extend the 72-hour regulatory deadline.
Q: Who needs to comply with GDPR, just data controllers or processors too?
A: Both controllers and processors have direct obligations under GDPR. Controllers bear primary responsibility for lawful processing, while processors must implement appropriate security measures, maintain processing records, assist controllers with compliance, and only process data on documented instructions. GDPR's dual accountability structure means both parties in a data sharing relationship must comply with relevant provisions.
Q: How long should data be retained under a DSA?
A: GDPR's storage limitation principle requires keeping personal data only as long as necessary for processing purposes. DSAs should specify retention periods aligned with these purposes. For example, "Party B shall retain customer service records for 24 months following case closure to enable quality review and regulatory compliance, then securely delete all records within 30 days." Retention periods should reflect legal requirements, business needs, and GDPR principles.
Q: What happens if a data processor violates both GDPR and the DSA?
A: The controller faces potential regulatory enforcement for failing to ensure processor compliance, while also having contractual remedies against the processor. The processor faces direct GDPR liability (supervisory authorities can fine processors under Article 83) plus contractual liability for DSA breaches. Affected individuals might have claims under GDPR Article 82 for damages. This multi-layered accountability explains why robust DSAs with clear obligations are essential risk management tools.
Q: Do internal data transfers within a company require DSAs?
A: Generally no, if data stays within a single legal entity. However, transfers between different legal entities within a corporate group typically require DSAs, especially if involving different jurisdictions. Additionally, transfers between a parent company and subsidiary often require DSAs since they constitute separate data controllers or controller-processor relationships.
Q: How often should DSAs be reviewed and updated?
A: Best practice suggests annual reviews at minimum, with immediate updates when significant changes occur—new processing activities, different data categories, changed security requirements, regulatory developments, or lessons learned from incidents. DSAs should include provisions specifying review schedules and amendment procedures.
Q: Can individuals see the DSAs that govern sharing of their data?
A: GDPR's transparency requirements mean individuals should understand how their data is shared, though they don't necessarily receive copies of DSAs. Privacy notices should explain data sharing practices in accessible language. Under access rights (Article 15), individuals can request information about recipients of their data, which might include relevant DSA details, though commercially sensitive contract terms may be redacted.
The relationship between GDPR and Data Sharing Agreements represents more than mere legal compliance; it reflects a fundamental shift in how organizations approach data stewardship. GDPR established that personal data protection is a right, not a privilege, while DSAs provide the contractual infrastructure to honor that right across organizational boundaries.
Understanding both frameworks and their interplay is essential for any organization participating in today's data-driven economy. GDPR sets non-negotiable standards that apply across millions of organizations and billions of individuals. DSAs translate those standards into specific, enforceable commitments tailored to particular relationships and circumstances.
The similarities between GDPR and DSAs, shared protective goals, emphasis on accountability, focus on security, and respect for individual rights create natural alignment. Organizations that embrace both frameworks as complementary elements of comprehensive data governance find that compliance becomes more manageable, not more burdensome.
Meanwhile, the differences between GDPR's regulatory authority versus DSAs' contractual nature, broad scope versus specific application, fixed requirements versus negotiable terms, explain why both are necessary. Neither substitutes for the other; each plays an indispensable role.
Ultimately, organizations that master the interplay between GDPR and DSAs tend to build trust with customers, partners, and regulators. They demonstrate through documented commitments that they take data protection seriously. In an era where data is simultaneously one of business's most valuable assets and one of its greatest risks, this combination of legal compliance and contractual clarity provides essential protection.
