Data Residency

Where is your data stored and processed?

Nscale: Norwegian data centres offer EEA data residency with renewable hydropower. UK facilities planned. Customer workloads stay on Nscale infrastructure. Norway option provides strong EU data residency.

Groq: All inference processed in US data centres. No EU data residency option available as of early 2026. European businesses processing personal data via the Groq API must implement GDPR transfer mechanisms.

Legal Jurisdiction

Which laws govern the company and your data?

Nscale: UK incorporation provides GDPR adequacy but UK CLOUD Act equivalent (Investigatory Powers Act) applies. Norwegian data centres under EEA law offer stronger protection for EU workloads.

Groq: Groq Inc. incorporated in California, subject to US law including the CLOUD Act. GDPR-compliant DPA available contractually, but US legal jurisdiction is the governing framework. No EU parent company or subsidiary structure.

UK incorporation provides GDPR adequacy but UK CLOUD Act equivalent (Investigatory Powers Act) applies. Norwegian data centres under EEA law offer stronger protection for EU workloads.

2/5

Groq Inc. incorporated in California, subject to US law including the CLOUD Act. GDPR-compliant DPA available contractually, but US legal jurisdiction is the governing framework. No EU parent company or subsidiary structure.

Data Retention & Training

Is your data used for model training?

Nscale: Infrastructure provider only—Nscale does not access, process, or retain customer workload data. Customers have full control over their compute environments.

Groq: Groq's privacy policy states that inference request data is not used for model training. Minimal data retention for API calls. Suitable for non-personal-data inference use cases; personal data processing requires GDPR transfer mechanism.

5/5

Infrastructure provider only—Nscale does not access, process, or retain customer workload data. Customers have full control over their compute environments.

4/5

Certifications

ISO 27001, SOC 2, Cyber Essentials, etc.

Nscale: No publicly listed certifications yet. Expected for a fast-growing infrastructure company at this stage. Data centre certifications likely in progress.

Groq: No published ISO 27001, SOC 2 Type II, or other independent security certifications as of early 2026. Privacy and security practices are self-attested. This is a significant gap for enterprise procurement in regulated industries.

2/5

Regulatory Fit

Suitability for regulated industries and professional services

Nscale: Strong for organisations needing European GPU compute sovereignty. Norwegian facilities particularly suitable for EU regulated workloads. UK incorporation is adequate but not optimal for strict EU sovereignty requirements.

Groq: Not suitable for GDPR-regulated personal data processing without appropriate SCCs and transfer impact assessment. Good option for non-personal-data use cases (e.g., inference on internal documents with no personal data). Not recommended for regulated EU industries without significant additional controls.

3/5

Strong for organisations needing European GPU compute sovereignty. Norwegian facilities particularly suitable for EU regulated workloads. UK incorporation is adequate but not optimal for strict EU sovereignty requirements.

2/5

Not suitable for GDPR-regulated personal data processing without appropriate SCCs and transfer impact assessment.
