Data Shield

An open-source component for detecting and replacing sensitive information before external models, preserving enough structure for downstream processing without exposing the original value.

Protection before the provider

Data Shield applies a simple rule: if a model does not need the real value to perform its task, that value should not leave the controlled environment. Protection occurs before the provider call, not after.

Type-aware detection

The layer can distinguish categories and apply different policies according to data type. Names, identifiers, accounts and other values do not have to receive the same treatment when the process needs to preserve part of the context.

Utility-preserving tokenization

Replacement is designed to reduce exposure without destroying document structure. Downstream components can continue relating repeated appearances and processing protected text without necessarily receiving the original value.

Open and auditable code

Source code and documentation are available on GitHub. The implementation can be audited, adapted and integrated without relying on an OrvixLabs black box.

Scope relative to Varexis

Data Shield provides a lightweight open boundary. When an operation requires enterprise policy, governed rehydration, separated permissions, signed evidence and broader fail-closed controls, Varexis occupies the higher architectural layer.

Not a regulatory certification

Reducing data exposure is a relevant technical control, but GDPR, HIPAA and other frameworks also depend on purpose, role, legal basis, contracts, retention, configuration and human operations.

// FAQ

Frequently asked questions

Does Data Shield replace Varexis?+

No. Data Shield is a free, open layer. Varexis adds broader enterprise governance, permissions, evidence and controls.

Is it enough to claim GDPR or HIPAA compliance?+

No. Reducing data exposure is one design control, not a regulatory certification.
