SOC 2 vs GDPR: What Each Covers and Where They Overlap

SOC 2 and GDPR: Different Frameworks, Related Goals

Organizations pursuing compliance often encounter both SOC 2 and GDPR. While they serve different purposes and originate from different parts of the world, they share a common goal: protecting data. Understanding how they relate -- and where they diverge -- helps organizations build efficient compliance programs that address both.

What Is SOC 2?

SOC 2 (System and Organization Controls 2) is an auditing framework developed by the American Institute of Certified Public Accountants (AICPA). It evaluates how well a service organization manages data based on five Trust Services Criteria:

The Five Trust Services Criteria

Criteria	Focus	Required?
Security	Protection against unauthorized access	Yes (always included)
Availability	System uptime and operational reliability	Optional
Processing Integrity	Accurate, complete, and timely data processing	Optional
Confidentiality	Protection of confidential information	Optional
Privacy	Collection, use, and disposal of personal information	Optional

SOC 2 Report Types

Type I -- evaluates the design of controls at a single point in time
Type II -- evaluates the design and operating effectiveness of controls over a period (typically 6-12 months)

Type II is significantly more valuable because it demonstrates that controls actually work over time, not just that they exist on paper.

Key Characteristics of SOC 2

Voluntary framework (not legally required)
US-centric but increasingly recognized globally
Assessed by independent CPA firms
Report scope is defined by the organization
No prescribed set of controls -- organizations design their own
Market-driven: customers and partners often require it

What Is GDPR?

The General Data Protection Regulation is an EU law governing the processing of personal data of individuals in the European Union:

Key GDPR Principles

Lawfulness, fairness, and transparency -- processing must have a legal basis
Purpose limitation -- data collected for specified purposes only
Data minimization -- collect only what is necessary
Accuracy -- keep data accurate and up to date
Storage limitation -- retain data only as long as needed
Integrity and confidentiality -- protect data with appropriate security
Accountability -- demonstrate compliance

Key Characteristics of GDPR

Legally mandatory for organizations processing EU resident data
Applies regardless of where the organization is based
Enforced by Data Protection Authorities with significant fining power
Prescriptive in many areas (data subject rights, breach notification, DPIAs)
Focuses on individual rights and organizational accountability
No certification or audit framework (compliance is self-assessed and regulator-reviewed)

Where They Overlap

Security Controls

Both frameworks require organizations to implement security measures to protect data:

Security Area	SOC 2 (Security Criteria)	GDPR (Article 32)
Access controls	Required	Required ("appropriate technical measures")
Encryption	Common control	Explicitly mentioned as appropriate measure
Monitoring	Required (detect anomalies)	Required (accountability principle)
Incident response	Required	Required (72-hour breach notification)
Vendor management	Required (sub-service organizations)	Required (processor obligations)
Risk assessment	Required	Required (DPIA for high-risk processing)

Organizational Controls

Both expect documented policies and procedures:

Written security and privacy policies
Employee training on data handling
Clear roles and responsibilities
Regular review and updates of controls
Change management procedures

Data Processing Integrity

Both care about data accuracy and integrity:

SOC 2's Processing Integrity criteria addresses data accuracy
GDPR's accuracy principle requires keeping personal data correct
Both require mechanisms to detect and correct errors

Where They Differ

Scope and Applicability

Aspect	SOC 2	GDPR
Legal status	Voluntary standard	Mandatory law
Geographic focus	US-originated, globally adopted	EU law, global reach
Applies to	Service organizations (by choice)	Any organization processing EU personal data
Enforcement	Market pressure (customer requirements)	Regulatory enforcement (fines up to 4% of global turnover)
Verification	Independent CPA audit	Self-assessment, regulator investigation

Individual Rights

GDPR grants specific, enforceable rights to data subjects. SOC 2 has no equivalent:

Right to access personal data
Right to rectification
Right to erasure ("right to be forgotten")
Right to data portability
Right to restrict processing
Right to object to processing
Rights related to automated decision-making

SOC 2's Privacy criteria addresses some privacy practices, but it does not create enforceable individual rights.

Data Transfer Restrictions

GDPR imposes specific restrictions on transferring personal data outside the EU/EEA. SOC 2 has no data residency or transfer requirements -- a SOC 2 report does not address where data is stored or whether cross-border transfers are lawful.

Breach Notification

GDPR -- mandatory 72-hour notification to supervisory authorities, plus individual notification if high risk
SOC 2 -- requires incident response procedures but does not mandate specific notification timelines

Consent and Legal Basis

GDPR requires a lawful basis for every processing activity. SOC 2 does not evaluate whether an organization has legal authority to process data -- only whether it protects the data it does process.

Can SOC 2 Help with GDPR Compliance?

Yes, but it is not sufficient on its own. Here is how SOC 2 supports GDPR compliance:

What SOC 2 Contributes to GDPR

Demonstrates security measures (GDPR Article 32)
Provides evidence of organizational controls
Shows vendor management practices
Documents incident response procedures
Demonstrates a culture of compliance

What SOC 2 Does Not Cover for GDPR

Lawful basis for processing
Data subject rights management
Cross-border data transfer mechanisms
Data Protection Impact Assessments
Data Protection Officer requirements
Specific breach notification timelines
Data minimization and purpose limitation
Data residency and sovereignty

Mapping SOC 2 to GDPR

GDPR Requirement	SOC 2 Coverage
Article 5 (Principles)	Partial (security principle covered, others not)
Article 6 (Lawful basis)	Not covered
Articles 12-23 (Data subject rights)	Not covered
Article 25 (Data protection by design)	Partially covered through security controls
Article 28 (Processor obligations)	Partially covered through vendor management
Article 30 (Records of processing)	Not covered
Article 32 (Security of processing)	Well covered
Article 33-34 (Breach notification)	Partially covered (detection, not notification timelines)
Article 35 (DPIA)	Not covered
Articles 44-49 (International transfers)	Not covered

Building an Efficient Compliance Program

For Organizations Needing Both

If you need both SOC 2 and GDPR compliance, build them together rather than separately:

Start with GDPR -- it is broader and legally required
Layer SOC 2 on top -- many GDPR security controls satisfy SOC 2 criteria
Use a unified control framework -- map controls to both requirements
Conduct combined assessments -- review controls against both frameworks simultaneously
Maintain shared documentation -- policies and procedures that serve both purposes

Technology Requirements

Both frameworks benefit from:

Robust access controls and authentication
Comprehensive audit logging
Encryption at rest and in transit
Data classification and handling procedures
Incident detection and response capabilities
Vendor risk management tools

Platforms like GlobalDataShield support both SOC 2 and GDPR compliance by providing the security controls, audit trails, and data residency capabilities that both frameworks value -- helping organizations address multiple compliance requirements through a single infrastructure choice.

Practical Tips

Do not treat SOC 2 and GDPR as separate projects
Assign a single team or individual to coordinate both programs
Use evidence from SOC 2 audits to demonstrate GDPR security measures
Use GDPR documentation to inform SOC 2 privacy criteria scope
Review both programs together during annual compliance reviews

Conclusion

SOC 2 and GDPR are complementary rather than redundant. SOC 2 provides third-party assurance of security controls that support GDPR compliance, while GDPR adds the legal framework, individual rights, and data governance requirements that SOC 2 does not address.

Organizations that understand where these frameworks overlap and diverge can build more efficient, comprehensive compliance programs. The goal is not to check two separate sets of boxes but to build a unified data protection program that satisfies both market expectations (SOC 2) and legal requirements (GDPR).
