GDPR and SOC 2: How They Overlap and Where They Don't
SaaS companies selling into both EU markets and US enterprise typically need to comply with both GDPR and SOC 2. The two frameworks have significant overlap in some areas and almost none in others. Understanding the difference saves real money and avoids the trap of treating them as one project.
This page covers what each framework actually requires, where the work overlaps, and how to sequence the two efficiently.
What each framework is
GDPR is EU privacy law, applicable from 2018. It is a binding regulation enforced by EU member state supervisory authorities, with maximum fines of 20 million euros or 4 percent of global annual turnover. It applies to any organization processing personal data of EU residents, regardless of where the organization is based.
SOC 2 is a private-sector audit framework developed by the AICPA, the American Institute of Certified Public Accountants. It is not a law. SOC 2 produces a report from an independent CPA firm attesting to the operating effectiveness of an organization's controls against the AICPA Trust Services Criteria. Enterprise buyers, particularly in the US, frequently require a SOC 2 Type 2 report before purchasing.
The two are different categories of compliance: GDPR is a legal obligation, SOC 2 is a market requirement.
What each framework covers
GDPR covers the lawful processing of personal data. The core obligations include having a lawful basis for processing, providing transparent notices to data subjects, honoring data subject rights (access, rectification, erasure, portability, objection), maintaining records of processing activities, conducting Data Protection Impact Assessments for high-risk processing, appointing a DPO where required, implementing appropriate technical and organizational security measures, managing international data transfers, notifying breaches within 72 hours, and managing relationships with processors via Data Processing Agreements.
SOC 2 evaluates controls against the AICPA Trust Services Criteria. There are five Trust Services Categories: Security (required for all SOC 2 reports), Availability, Processing Integrity, Confidentiality, and Privacy. Each category breaks down into specific criteria covering areas like access controls, system operations, change management, risk mitigation, monitoring, and incident response.
A typical SOC 2 Type 2 report covers Security as a minimum, often plus Availability and Confidentiality. The Privacy category is optional and less commonly included.
Where they overlap
The overlap between GDPR and SOC 2 is in the security controls layer. Both frameworks expect:
Access controls. Limiting access to personal data to authorized personnel, with role-based access, multi-factor authentication, and regular access reviews.
Encryption. Encryption of personal data in transit and at rest using appropriate algorithms.
Logging and monitoring. Logs of access to personal data, monitoring for unauthorized access, retention of logs for appropriate periods.
Change management. Documented change management processes for systems that handle personal data.
Vendor management. Documented vendor risk assessment processes, with executed DPAs (GDPR Article 28) and security assessments.
Incident response. Documented incident response procedures, with breach notification capability.
Backup and recovery. Documented backup procedures with periodic testing.
Personnel security. Background checks, training, and confidentiality obligations for personnel handling personal data.
If you build a good SOC 2 Type 2 program, you address most of the security and operational expectations of GDPR. The Trust Services Criteria for Security alone covers a substantial portion of GDPR Article 32 (security of processing).
Where they do not overlap
The non-overlapping parts of GDPR are everything that is privacy-specific rather than security-generic:
Lawful basis for processing. SOC 2 does not require you to have or document a lawful basis. GDPR requires this for every processing activity.
Privacy notices and transparency. SOC 2 does not require GDPR-compliant privacy notices. GDPR Articles 13 and 14 have specific content requirements.
Data subject rights. SOC 2 does not require operational capability to handle DSARs, deletion requests, or other GDPR rights. GDPR Articles 15 through 22 require functional response capability.
Records of Processing Activities. SOC 2 does not require GDPR RoPA. GDPR Article 30 requires it for most organizations.
Data Protection Impact Assessments. SOC 2 does not require DPIAs. GDPR Article 35 requires them for high-risk processing.
DPO appointment. SOC 2 does not address DPO requirements. GDPR Article 37 requires DPO appointment in specific circumstances.
International data transfers. SOC 2 does not require transfer impact assessments or Standard Contractual Clauses. GDPR Chapter V does.
Lawful processing of special category data. SOC 2 does not require explicit consent or other Article 9 grounds for health, biometric, or other special category data. GDPR does.
Children's data. SOC 2 has no specific children's data requirements. GDPR Article 8 has specific requirements for children.
How to sequence the two
For most SaaS companies, the right order is:
Start with GDPR if you have EU customers or plan to. GDPR is a legal obligation; failing to comply can result in fines and enforcement action. Building a privacy program early is significantly cheaper than retrofitting one later.
Add SOC 2 when enterprise sales requires it. SOC 2 is typically driven by US enterprise buyer demand. Most SaaS companies hit the trigger when their first major US enterprise buyer asks for the report.
Use GDPR work as foundation for SOC 2. If your GDPR program includes solid Article 32 security measures (access controls, encryption, logging, incident response), much of the SOC 2 Security category is already built. The remaining work is documentation and audit preparation rather than new controls.
Avoid the reverse path. Building SOC 2 first and then trying to add GDPR usually means significant rework because privacy-specific requirements (consent, transparency, rights, DPO) were not designed into the program.
Realistic timelines and costs
GDPR program build: 3 to 6 months for initial program, then ongoing maintenance. Fractional DPO costs 500 to 5,000 EUR per month depending on tier.
SOC 2 Type 1 (point-in-time): 3 to 6 months from kickoff to report. Total cost typically 50,000 to 150,000 USD including platform (Vanta, Drata, Secureframe), auditor, and consulting.
SOC 2 Type 2 (12-month operational period): 12 to 15 months from kickoff to first report, since the audit covers a 12-month operating period. Total cost similar to Type 1 plus auditor fees for the longer audit.
Combined GDPR + SOC 2 cost: typically 60,000 to 200,000 USD over 12 to 15 months for a mid-stage SaaS company.
Who handles each
GDPR work is typically led by a DPO (full-time, fractional, or outsourced). Legal aspects may involve outside privacy counsel.
SOC 2 work is typically led by a Head of Security, Head of Engineering, or a dedicated Compliance Manager, supported by a SOC 2 automation platform (Vanta, Drata, Secureframe) and a SOC 2 audit firm (one of the AICPA-licensed CPA firms).
The two can be coordinated by a single program manager or by combined privacy plus security consulting firms.
How Engage Compliance fits
Engage Compliance provides the GDPR and privacy compliance side. Most of our SaaS clients pair us with a SOC 2 platform like Vanta or Drata for the security automation side.
We design the GDPR program to support SOC 2 readiness, so the security and operational controls do not need to be redesigned when SOC 2 work begins. We coordinate with your SOC 2 auditor and platform during their audit cycle.
For clients who want privacy plus security bundled in one engagement, we recommend providers like Workstreet that offer combined services. We are specifically focused on privacy.
