Understanding the Difference Between DPAs and NDAs: What You Need to Know

Subscribe to our Newsletter

Imagine your company is about to share sensitive information or personal data with a vendor, partner, or service provider. Perhaps you’re onboarding a cloud service for customer management or collaborating with a research institution handling health data. Before you finalize any exchange, there are two important contracts you might consider: a Data Processing Agreement (DPA) and a Non-Disclosure Agreement (NDA). While both relate to handling information, they serve very different purposes and come with distinct obligations.

Understanding when and why to use a DPA versus an NDA can help avoid costly missteps, tightly manage compliance risks, and protect your organization’s valuable data assets—especially as data privacy regulations become increasingly strict worldwide.

What Is a Data Processing Agreement (DPA), and How Does It Differ from an NDA?

A Data Processing Agreement (DPA) is a specialized contract focused on governing how personal data is processed, particularly when a third party processes data on behalf of a company.

By contrast, a Non-Disclosure Agreement (NDA) is a contract designed to protect confidential information from unauthorized disclosure. NDAs can be unilateral or mutual, but they do not inherently cover how data must be processed, secured, or managed under data privacy laws.

While sometimes confused or treated interchangeably, DPAs and NDAs have unique roles:

DPA Focus: Ensuring lawful and compliant handling of personal data, specifying obligations related to security, breach notification, audits, cross-border transfers, and data subjects’ rights.
NDA Focus: Protecting any kind of confidential information, including trade secrets, business plans, or proprietary technology, without specifically addressing legal data protection requirements.

There is also the Confidential Disclosure Agreement (CDA), sometimes used similarly to NDAs but generally emphasizing mutual confidentiality obligations. CDAs rarely address data processing compliance unless custom-tailored.

To see practical examples and detailed definitions, you can explore Sirion’s overview of Data Processing Agreements and the guide on Non-Disclosure Agreements.

Why Are DPAs Necessary When Working with Third-Party Processors?

If your business relies on third-party vendors to handle your data, especially personal information, data privacy regulations such as GDPR and CCPA require clear contractual terms governing data processing activities. DPAs serve as that legal and operational foundation.

Here’s why DPAs are important:

Clarify Roles: Define controller vs. processor responsibilities.
Specify Scope: Describe what data is processed and why.
Impose Security Measures: Require appropriate safeguards.
Set Breach Protocols: Establish reporting obligations.
Control Cross-Border Transfers: Address global data movement.
Allow Audits: Enable verification of compliance.
Address Sub processors: Govern subcontractor involvement.
Allocate Liability: Define accountability for non-compliance.

Without a DPA, your company risks regulatory penalties and data breaches. NDAs alone cannot replace the compliance safeguards required in a DPA.

To understand specific elements in CLM context, see Sirion’s detailed explanation on DPAs.

What Are the Key Components of a DPA?

A typical DPA includes:

Purpose and Scope of Processing: Types of data and processing activities.
Roles and Responsibilities: Controller and processor duties.
Security Measures: Required technical and organizational controls.
Sub processor Management: Approval and oversight conditions.
Breach Notification: Reporting timelines and procedures.
Data Subject Rights Assistance: Support for access or deletion requests.
Data Transfers: Cross-border compliance requirements.
Audit Rights: Inspection and verification rights.
Data Retention and Deletion: Terms for secure deletion post-contract.
Liability and Indemnification: Responsibilities if obligations are breached.

When Is an NDA Still Important?

While DPAs govern personal data processing, many relationships involve other confidential information such as business strategies or proprietary technology. NDAs protect this information and prevent unauthorized disclosure.

An NDA can complement a DPA but cannot replace it where data privacy compliance is legally required.

For examples of NDA clauses, see Non-Disclosure Agreements.

How Do DPAs Fit Into the Bigger Picture of Data Privacy Regulations?

DPAs apply across global data privacy laws:

EU GDPR: Requires DPAs for controller–processor relationships.
CCPA (California): Requires contractual limits on personal data use.
Other Jurisdictions: Brazil, Canada, Australia, Japan have similar expectations.

DPAs are also essential for cross-border transfers, often used alongside Standard Contractual Clauses.

What Happens If You Confuse or Misuse DPAs and NDAs?

Many organizations mistakenly believe an NDA alone covers data privacy and protection needs, leading to potential pitfalls:

Insufficient Legal Compliance: NDAs rarely meet detailed regulatory expectations, risking fines and legal actions.
Inadequate Security Requirements: NDAs don’t typically specify technical or organizational security measures necessary to protect personal data.
Breach Response Gaps: NDAs usually don’t define breach notification timelines or procedures.
Ambiguous Responsibilities: NDAs may not clarify subprocessors’ use or audit rights, exposing organizations to hidden risks.

Conversely, over-relying solely on DPAs without an NDA may leave confidential business information vulnerable.

Clear understanding and appropriate contract use help avoid misunderstandings, regulatory issues, and damage to business reputation.

How to Start Drafting or Reviewing a DPA

If your organization processes personal data through vendors or partners, consider these practical steps:

1. Identify Roles: Determine who is the data controller and who will act as processors.
2. Map Data Flows: Understand what data is processed, why, and where.
3. Evaluate Risks: Assess the sensitivity and regulatory landscape of your data.
4. Use Proven Templates: Start with standard clauses tailored to your context.
5. Clarify Responsibilities: Define clear rights on breach notifications, audits, sub processors, and liability.
6. Involve Legal and Compliance Teams: Ensure contract terms satisfy local and global data protection laws.
7. Integrate Into Contract Lifecycle Management (CLM): Manage DPAs systematically alongside other contracts using platforms like Sirion CLM to maintain visibility, compliance, and renewal tracking.

Beyond Basics: Industry-Specific DPA Considerations

Though the core DPA principles apply broadly, some industries face unique challenges:

Healthcare: Patient data handling often requires HIPAA alignment in the U.S. and additional breach reporting.
FinTech: Financial data processing must incorporate stringent security controls and compliance with PCI DSS.
Education and Research: Data sharing for academic collaboration involves careful attention to consent and purpose limitations.
SaaS Providers: Managing multi-tenant environments with subprocessors demands robust subprocessor clauses and data segregation.

Real-world industry scenarios emphasize the importance of tailoring DPAs while preserving essential compliance.

Conclusion: Aligning Data Protection and Confidentiality Through the Right Agreements

While both Data Processing Agreements (DPAs) and Non-Disclosure Agreements (NDAs) play roles in safeguarding information, their functions are fundamentally distinct. A DPA is a regulatory necessity—ensuring lawful handling of personal data under frameworks like GDPR, CCPA, and HIPAA—while an NDA is a business safeguard, protecting broader confidential information such as intellectual property, trade secrets, or strategic insights.

Organizations that understand when to deploy each agreement—and how they complement one another—can strengthen both compliance and trust. Used together, they create a layered defense: NDAs secure confidentiality, and DPAs ensure data privacy compliance across vendors, partners, and subprocessors.

By managing these agreements within an AI-native Contract Lifecycle Management (CLM) platform like Sirion, businesses can centralize oversight, automate compliance checks, and maintain visibility into their evolving data obligations. This proactive approach not only minimizes regulatory risk but also builds operational resilience in an increasingly privacy-driven world.

Frequently Asked Questions (FAQs)

Can an NDA replace a DPA if I want to protect my company’s data?

No. While an NDA protects confidential information from disclosure, it doesn’t meet the specific legal and operational requirements related to personal data processing set by regulations like GDPR or CCPA. A DPA is necessary when a third party processes personal data on your behalf to ensure compliance.

Who typically signs a DPA?

A DPA is signed between the data controller, who determines the purposes and means of processing personal data, and the data processor, who processes data on behalf of the controller. Sometimes, subprocessors may also need DPAs with the primary processor.

Are DPAs only relevant for companies operating in Europe?

No. Although the GDPR popularized DPAs, data privacy laws worldwide increasingly require such agreements whenever personal data is shared with third parties. This includes the U.S. (CCPA), Canada (PIPEDA), Brazil (LGPD), and others.

What happens if a processor breaches the terms of a DPA?

The DPA typically outlines breach notification timelines and liability. If a breach occurs, the processor must notify the controller promptly. Liability provisions may include financial damages or indemnification depending on contract terms.

How do DPAs handle cross-border data transfers?

DPAs usually incorporate safeguards such as Standard Contractual Clauses or rely on adequacy decisions to ensure personal data transferred internationally complies with privacy laws. This is critical for global companies with vendor ecosystems across countries.

Can I use standardized DPA templates for all vendors?

Standard templates are a great starting point but should be customized based on specific data flows, risks, regulatory requirements, and vendor roles. Working with legal and compliance teams to tailor clauses ensures adequacy.

How often should DPAs be reviewed or renewed?

DPAs should be reviewed:

When there are changes in processing activities
Upon regulatory updates or new guidance
At contract renewal intervals, to reassess risk and compliance posture
