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.

Fireworks AI: US-only data centres. No EU data residency available. Personal data inference requires GDPR SCCs and transfer impact assessment.

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.

1/5

US-only data centres. No EU data residency available. Personal data inference requires GDPR SCCs and transfer impact assessment.

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.

Fireworks AI: California incorporation, subject to US law and CLOUD Act. GDPR DPA available for enterprise customers. No EU legal 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.

2/5

California incorporation, subject to US law and CLOUD Act. GDPR DPA available for enterprise customers. No EU legal 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.

Fireworks AI: Inference data not used for shared model training per privacy policy. Minimal logging for API requests. Reasonable baseline for a developer-focused inference API.

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

Inference data not used for shared model training per privacy policy. Minimal logging for API requests. Reasonable baseline for a developer-focused inference API.

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.

Fireworks AI: No published ISO 27001 or SOC 2 Type II certifications as of early 2026. Early-stage company with self-attested security posture. Not yet suitable for enterprise regulated-industry procurement.

2/5

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

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.

Fireworks AI: Suitable for development, prototyping, and non-personal-data inference workloads. US jurisdiction and lack of certifications make it unsuitable 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

Suitable for development, prototyping, and non-personal-data inference workloads. US jurisdiction and lack of certifications make it unsuitable for regulated EU industries without significant additional controls.
