Data Residency

Where is your data stored and processed?

Together AI: All inference and fine-tuning workloads processed in US data centres. No EU data residency option. GDPR transfer mechanisms (SCCs) required for European personal data processing.

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.

1/5

All inference and fine-tuning workloads processed in US data centres. No EU data residency option. GDPR transfer mechanisms (SCCs) required for European personal data processing.

4/5

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.

Legal Jurisdiction

Which laws govern the company and your data?

Together AI: Incorporated in Delaware, US. Subject to CLOUD Act. GDPR DPA available for enterprise customers contractually, but US jurisdiction governs. No EU subsidiary structure.

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.

2/5

Incorporated in Delaware, US. Subject to CLOUD Act. GDPR DPA available for enterprise customers contractually, but US jurisdiction governs. No EU subsidiary structure.

3/5

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.

Data Retention & Training

Is your data used for model training?

Together AI: Clear policy that customer data and fine-tuning datasets are not used to train shared models. Fine-tuned model weights are customer property. Good baseline for data isolation, but residency limitation remains.

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

Certifications

ISO 27001, SOC 2, Cyber Essentials, etc.

Together AI: No published ISO 27001, SOC 2 Type II, or independent security certifications as of early 2026. Security practices are self-attested. Significant gap for enterprise procurement in regulated industries.

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

Regulatory Fit

Suitability for regulated industries and professional services

Together AI: Not suitable for GDPR-regulated personal data processing without SCCs and TIA. Good for development, prototyping, and non-personal-data AI workloads. US jurisdiction and absence of certifications limit suitability for regulated EU industries.

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.

2/5

Not suitable for GDPR-regulated personal data processing without SCCs and TIA. Good for development, prototyping, and non-personal-data AI workloads. US jurisdiction and absence of certifications limit suitability for regulated EU industries.
