Healthcare & NHS

Patient data doesn't stop at the ward boundary.

VestraData discovers and anonymises regulated patient data across clinical databases, NHS network segments, and research repositories — entirely within your air-gapped environment.

Regulatory context

The frameworks your auditors will cite.

NHS DSPT

Data Security and Protection Toolkit obligations for NHS organisations handling patient data.

HIPAA §164

Safe harbour and expert determination standards for de-identification of protected health information.

ICO AI in Health Guidance

Information Commissioner expectations for lawful basis and data minimisation when deploying AI in healthcare.

UK GDPR Special Category Data

Health data requires explicit lawful basis and a higher standard of technical protection.

In practice

What Healthcare & NHS teams actually use it for.

01Clinical database PII discoveryScan patient record systems, clinical databases, and research repositories. Field-level PII findings with confidence scores and row counts. No schema knowledge required. Air-gapped: scans run entirely within your NHS network.

02Air-gapped deployment inside NHS network segmentsVestraData and VestraShield run entirely inside your NHS network. No internet dependency at runtime. ML models bundled in the install package. NHS DSPT compliant from the ground up. Zero data egress.

03Patient record anonymisation for research data handoffsGenerate synthetic datasets that preserve statistical distribution for research use, without exposing real patient identifiers. Differential privacy mode for UK GDPR compliant outputs.

04DSPT audit evidence from scan findingsEvery field discovered, every anonymisation applied, and every data processing decision is written to a hash-chained, tamper-evident audit record. DSPT evidence submissions are generated directly from scan findings — not assembled manually.

Platform capabilities

How VestraData maps to this environment.

Air-gap, no internet at runtime

Entire ML stack runs offline inside your NHS network. No phone-home. No data egress to vendor infrastructure. Required for NHS networks with strict data residency.

NHS DSPT alignment

Deployment architecture designed to satisfy DSPT requirements. Audit log provides evidence for annual DSPT submissions.

Differential privacy for research exports

GDPR and HIPAA compliant synthetic data generation. Statistical distribution preserved. Real patient identifiers never appear in research outputs.

Clinical entity types

NHS number, patient identifier, ward reference, and custom clinical codes handled by zero-shot GLiNER. No model retraining required.

On-premises Helm / Kubernetes

Helm chart deployment for larger NHS environments. Docker Compose for ward or trust-level deployments. LDAP and SAML for NHS identity integration.

Immutable DSPT audit evidence

Hash-chained audit record for every data processing activity. Exported directly into DSPT evidence submissions.

Companion tool · VestraShield

Clinical staff are using AI tools. Patient identifiers shouldn't be going with them.

VestraShield intercepts every prompt from clinical documentation tools, decision support AI, and admin applications. Patient identifiers are replaced before any request leaves your network.

Clinical AI tool interceptCovers AI tools used for clinical documentation, decision support, and administrative tasks. Typed prompts and file uploads intercepted before they leave your network.
Patient identifier transformationNHS number, patient name, date of birth, and ward identifiers replaced with consistent surrogates before any prompt reaches an external LLM. Restored in the response.
Air-gap operationVestraShield intercepts within your NHS network segment. No prompt content or patient data egresses to vendor infrastructure during interception.
Policy engine for clinical usersDifferent rules for clinical staff, administrative staff, and IT teams. Per-ward and per-role policy configuration. No coding required.
