HIPAA requires covered entities and business associates to safeguard Protected Health Information (PHI) at rest, in motion, and in use. But compliance is about more than policies – it’s about ensuring PHI is never exposed in the first place.
Schedule a Demo
Replace PHI with secure tokens or masked values so raw identifiers never appear in systems.
Locate PHI across structured, unstructured, on-prem, and cloud environments.


Enforce role-based, “minimum necessary” access to PHI.
Deploy on-prem, in the cloud, or hybrid — no application rewrites.

DataStealth replaces sensitive identifiers (e.g., SSNs, medical record numbers) with tokens or masked values. Applications, analytics, and workflows run unchanged, but PHI is never exposed.
Reduce HIPAA compliance risk by protecting identifiers at the source.
Preserve existing applications: no rewrites, no agents.
Extend protection seamlessly across cloud and on-prem systems.
Unstructured notes, databases, logs, and file shares often hide PHI. DataStealth scans, discovers, and classifies sensitive data automatically, so nothing is left unprotected.
Full visibility into PHI locations across your environment.
Simplified audit and compliance reporting.
Reduced breach risk by surfacing unknown data stores.
HIPAA’s “minimum necessary” rule means not every user should see full PHI. DataStealth applies dynamic masking so clinicians, researchers, or support staff only see what they need.
Enforce HIPAA’s least-privilege requirements automatically.
Reduce insider threat and accidental disclosure.
Balance security with operational usability
Whether your systems run on legacy EMRs, on-prem mainframes, or cloud analytics, DataStealth deploys inline – at gateways, sidecars, or service meshes – with no application changes.
Fast deployment with no code changes.
Consistent protection across hybrid environments.

With DataStealth, HIPAA compliance isn’t just about avoiding penalties. It’s about reducing breach risk, simplifying audits, and building patient trust by showing you take data protection seriously.
Get a sessionThe minimum necessary standard is one of HIPAA's core principles — it requires that covered entities limit PHI access, use, and disclosure to the minimum amount needed to accomplish a given purpose. A billing clerk shouldn't see clinical notes. A researcher shouldn't see patient names. A support agent shouldn't see full Social Security Numbers.
Most organizations enforce this through application-level RBAC — i.e., hardcoded role permissions within each system. The problem is that roles are coarse-grained, inconsistent across applications, and expensive to maintain.
DataStealth enforces minimum necessary at the data layer through attribute-based dynamic masking.
On every request, the platform evaluates the user's role, department, location, and device posture — then masks, partially reveals, or grants full access to each PHI field accordingly.
No application code changes are needed, and the same policy applies consistently across every system in the estate — from legacy EMRs to cloud platforms to SaaS applications.
HIPAA provides two methods for de-identifying PHI — the Expert Determination method (§164.514(b)(1)) and the Safe Harbor method (§164.514(b)(2)).
Under Safe Harbor, organizations must remove 18 specific identifiers (names, dates, ZIP codes, SSNs, MRNs, etc.) and confirm that no residual information could re-identify an individual.
Tokenization satisfies Safe Harbor by replacing each identifier with a format-preserving token that has no mathematical relationship to the original value. Unlike encryption — which can be reversed with a key — tokenization produces surrogates that cannot be used to reconstruct the original PHI, meeting HIPAA's standard for rendering data non-identifiable.
DataStealth applies tokenization in-flight at the protocol layer, covering all 18 Safe Harbor identifiers across databases, file shares, and SaaS applications.

HIPAA's Security Rule requires administrative, physical, and technical safeguards for all systems that create, receive, maintain, or transmit ePHI. Every such system is in scope for risk analysis, access control documentation, audit logging, and breach preparedness.
DataStealth reduces the number of systems handling ePHI by tokenizing PHI in-flight — before it reaches downstream databases, test environments, analytics platforms, or partner systems.
Systems that only process tokens are no longer handling ePHI — reducing the number of systems subject to Security Rule safeguards.
The cost impact mirrors what organizations see with PCI DSS scope reduction — fewer systems to assess, fewer controls to document, and faster audit cycles.
For healthcare organizations and insurance companies subject to both HIPAA and PCI, DataStealth provides unified protection from a single platform.
HIPAA (1996) established the foundational privacy and security framework for PHI. HITECH (2009) extended HIPAA's reach in three critical ways — it made business associates directly liable for HIPAA violations, introduced mandatory breach notification requirements, and dramatically increased penalties (up to $1.5M per violation category per year).
For data security, the practical impact is that HITECH raised the cost of non-compliance and expanded the scope of who must comply.
Business associates — i.e., cloud vendors, SaaS providers, analytics partners, and offshore support teams that handle PHI on behalf of covered entities — now face the same penalties as the covered entities themselves.
DataStealth addresses both by ensuring PHI is tokenized or masked before it reaches business associates. The associate's systems process tokens — not ePHI — which fundamentally changes their risk profile.
For cross-border scenarios where PHI flows to vendors in other jurisdictions, tokenization ensures no personal health information ever leaves the mandated boundary.
