Organizations offering these services and software solutions for research purposes include:
Datavant : Specializes in privacy-preserving data matching, tokenization, and de-identification, allowing researchers to link disparate health datasets securely without exposing patient identities.[]()
Yes. There are several types of providers, ranging from specialized privacy consultancies to healthcare data platforms. For research use, I’d distinguish between vendors that actually perform the de-identification and vendors that primarily provide access to already de-identified datasets.
Examples of providers
Datavant — Provides HIPAA de-identification services, including Expert Determination, remediation of datasets, unstructured/free-text de-identification, tokenization, and privacy-risk assessments. It specifically markets these services to researchers and life-sciences organizations.
Privacy Analytics (by IQVIA) : Delivers enterprise software and expert determination services designed to transform sensitive health data into de-identified datasets for secondary research.[](https://guides.library.jhu.edu/protecting_identifiers/software)
Specialized statistical/privacy consultants — HHS notes that Expert Determination can be performed by a qualified person with appropriate knowledge and experience in statistical/scientific methods for rendering health information non-identifiable. There isn't a particular government certification or degree that makes someone an "expert."
Healthcare data/analytics companies — Some firms combine de-identification with data curation, linkage, and research-data delivery. This can be useful if you need more than simply removing identifiers—for example, preserving longitudinal patient relationships or linking records across datasets.
What you should look for
For a research project involving U.S. PHI, I'd specifically ask a vendor whether it provides:
HIPAA Safe Harbor de-identification — removal of the specified identifiers.
HIPAA Expert Determination — a qualified expert assesses whether the re-identification risk is sufficiently small and documents the methodology.
De-identification of free text/clinical notes — important because names, dates, locations, etc. can occur inside narrative notes.
Tokenization/pseudonymization — particularly if you need to maintain patient-level linkage across encounters or datasets.
A formal report/certification documenting the methodology and residual identification risk.
Data-use/research agreements and security controls appropriate to your institution and IRB requirements.
One important distinction: pseudonymization/tokenization isn't automatically the same thing as HIPAA de-identification. Under HIPAA, the dataset needs to satisfy either Safe Harbor or the Expert Determination method. HHS explicitly recognizes both approaches.
If you tell me what kind of healthcare data you have (EHR, claims, clinical notes, imaging, genomics, registry data, etc.) and approximately how large the dataset is, I can give you a shortlist of 5–10 actual vendors that provide the service, including typical use cases and how they differ.
Yes. There are several types of providers, ranging from specialized de-identification vendors to consulting firms and research-focused platforms.
Providers to consider
Info Incognito — Provides outsourced de-identification of healthcare records and medical images, including HIPAA Safe Harbor and Expert Determination approaches. It specifically markets its services to healthcare, pharmaceutical, and research organizations.
Inference Systems — Offers automated de-identification pipelines for clinical text, images, and structured data, aimed at creating research-ready datasets.
Maxiom Labs — Provides engineering services for healthcare de-identification pipelines, including structured and free-text PHI, risk assessment, and audit trails.
SynapseHealthTech / PrivaSure — Offers a platform combining Safe Harbor, Expert Determination, and tokenization for secondary research and external data sharing.
Synthology Healthcare Solutions / XyDromatics — Focuses on clinical reports and medical imaging, with Expert-Determination de-identification, pseudonymization, date shifting, free-text processing, and removal of burned-in image identifiers.
ArcherHall / Philter — A research-oriented clinical-text de-identification approach that has been evaluated for HIPAA de-identification and certification of de-identified clinical notes.
An important distinction for research
If you're preparing PHI for a research study, don't just look for a vendor that says "HIPAA compliant." Under the HIPAA Privacy Rule, there are two recognized de-identification routes:
Safe Harbor — removal of the specified HIPAA identifiers.
Expert Determination — a qualified expert applies statistical/scientific methods and documents that the risk of identification is very small.
For research datasets where you need to retain useful dates, geography, longitudinal information, rare conditions, or detailed clinical text, Expert Determination is often particularly relevant, because Safe Harbor can remove information researchers need. HHS explicitly notes that the appropriate approach depends on the particular dataset and intended use.
If you tell me what kind of healthcare data you have (EHR/claims, clinical notes, DICOM images, genomics, registry data, etc.) and whether you need a service provider to perform the de-identification versus software you can run internally, I can narrow this to the most relevant providers and compare them on research use, HIPAA Expert Determination, BAA availability, data residency, pricing model, and ability to handle free text/images.
Academic Medical Centers & Universities : Most major research universities and hospital systems maintain internal Honest Broker groups or Informatics cores (such as CTSAs—Clinical and Translational Science Awards recipients). An honest broker acts as an independent intermediary. They extract identifiable clinical data from Electronic Health Records (EHRs), de-identify it, and pass safe datasets to internal or external researchers without exposing patient identities.[](https://casrai.org/guides/honest-broker-de-identified-data-role-human-subjects-research)
NLM-Scrubber (NIH) : Developed by the U.S. National Library of Medicine at the National Institutes of Health, this is a freely available tool designed specifically to scrub clinical narrative text to meet HIPAA Safe Harbor guidelines.[]()
If you're looking for a service or tool, tell me:
Are you working with structured data (spreadsheets/databases) or unstructured text/imaging?
Do you need an external vendor certification (Expert Determination) or an internal software tool?
Yes. There are several types of providers, depending on whether you need a service to de-identify your own research data, software/API, or already-de-identified datasets.
Providers to consider
Datavant — Provides health-data privacy and de-identification capabilities, including HIPAA Expert Determination and de-identification of unstructured text. It is particularly relevant for organizations working with large-scale real-world data and research datasets.
Microsoft Azure Health Data Services — Offers a cloud/API-based de-identification service for clinical text. It can identify, redact, or replace PHI, including the HIPAA 18 identifiers, and is explicitly intended for healthcare/life-sciences research and data-sharing workflows.
IRI — Provides software for discovering and de-identifying PHI across structured and unstructured healthcare data, including databases, HL7/FHIR, DICOM, PDFs, free text, and other formats. It supports both Safe Harbor and Expert Determination workflows.
Maxiom Labs — Offers engineering services for healthcare de-identification pipelines, including structured data, free text, re-identification-risk assessment, and audit trails aimed at research and AI/analytics use cases.
Synthology / XyDromatics — Offers a dedicated de-identification engine for clinical studies and reports, using an Expert Determination approach and supporting free-text and imaging-related identifiers.
Academic/institutional honest-broker services — Some universities and health systems provide de-identification as part of their research-data services. For example, the University of Cincinnati's Center for Health Informatics acts as an "Honest Broker" and can obtain, manage, de-identify, and release clinical data for IRB-approved research.
UPMC / Ahavi — If you're looking for research-ready de-identified healthcare data rather than de-identification of your own data, Ahavi provides de-identified real-world healthcare data and analytics environments for researchers.
An important distinction
If you're sending an existing patient dataset to a third party for de-identification, I'd look specifically for a provider that can document HIPAA Expert Determination, rather than simply advertising "anonymization." HHS recognizes two HIPAA de-identification methods: Safe Harbor and Expert Determination. Expert Determination involves a qualified expert assessing re-identification risk and documenting the methodology and results.
Also, a BAA and appropriate security controls can matter when the vendor receives PHI before de-identification. HHS specifically notes that a business associate can perform de-identification on behalf of a covered entity when authorized by the applicable business associate agreement.
If you tell me what kind of healthcare data you have (EHR, clinical notes, claims, imaging/DICOM, genomics, registry, etc.) and roughly how large it is, I can narrow this to 5–10 vendors that actually provide outsourced de-identification services, rather than software you would have to implement yourself.
Yes. There are several types of providers, depending on whether you need software/API de-identification, a managed de-identification service, or research-ready datasets.
Notable providers
Microsoft — Azure Health Data Services: Provides a dedicated de-identification API for clinical notes, transcripts, messages, and clinical-trial text. It can extract, redact, or surrogate PHI and is specifically intended for healthcare/life-sciences use cases including research.

RACube: Offers automated de-identification of unstructured clinical notes, aimed at research, AI, analytics, and data partnerships.
LexisNexis — Gravitas for Healthcare: More of a research-ready real-world-data offering than a generic de-identification service. It provides de-identified longitudinal healthcare datasets and uses expert determination for HIPAA de-identification.
What matters for research
If you're working with U.S. patient data, the key question isn't simply whether a vendor says its product is "HIPAA compliant." HHS recognizes two HIPAA de-identification methods: Safe Harbor and Expert Determination.
For a research project, I'd evaluate vendors on:
Data type: EHR tables, claims, clinical notes, pathology, DICOM/images, genomics, etc.
De-identification method: Safe Harbor vs. documented Expert Determination.
Residual-risk assessment: Whether they quantify or document re-identification risk.
Dates: Whether dates are removed, generalized, or consistently shifted.
Longitudinal linkage: Whether patients can remain consistently pseudonymized across records.
Research utility: Whether clinical meaning is preserved.
BAA/security: If the vendor receives PHI before de-identification, determine whether a Business Associate Agreement and appropriate safeguards are required.
IRB/privacy requirements: HIPAA de-identification doesn't automatically resolve every institutional or research-governance requirement.
If you tell me what kind of healthcare data you have (EHR/clinical notes, claims, imaging, genomics, etc.), approximately how much, and whether you want a vendor to perform the service or an API/software you operate yourself, I can narrow this to the 5–10 best-fit providers and compare pricing, HIPAA methodology, capabilities, and research use cases.
John Snow Labs: Famous for its Spark NLP for Healthcare ecosystem, they provide robust on-premise or cloud-deployable software tools that automatically find and obfuscate PHI across clinical text notes, scanned PDFs, structured database files, and even DICOM medical images (with pixel inpainting) while retaining referential integrity for longitudinal research.

Are you looking to de-identify unstructured clinical text/notes, structured database files , or medical images ? Let me know and I can detail which compliance method (Safe Harbor vs. Expert Determination) fits your specific project.
Yes. There are several types of organizations that provide healthcare data de-identification for research, ranging from specialized privacy firms to large healthcare-data companies and software vendors.
Leading providers
Datavant — One of the strongest options if you need a managed de-identification service, rather than simply software. Its Privacy Hub provides HIPAA de-identification analyses, Expert Determination, remediation, risk assessments, and de-identification of unstructured clinical text. Datavant specifically positions these services for research and data sharing.
IQVIA — Particularly relevant if you need research-ready, non-identified healthcare data as well as research services. IQVIA provides non-identifiable claims and EMR datasets and makes certain datasets available to approved academic researchers.
Optum / Microsoft Azure Health Data Services — Offers a de-identification service that uses machine learning to identify and redact or replace PHI, including the HIPAA 18 identifiers. This is more appropriate when you want a technical de-identification capability integrated into a data platform.
Specialized clinical-text de-identification vendors/tools — For EHR notes, pathology reports, discharge summaries, and other free text, tools such as Philter, NLM Scrubber, CliniDeID, and PhysioNet DeID are used in research workflows. These tend to be software/tools rather than full-service privacy consultancies.

One important distinction: “de-identified” isn't synonymous with simply removing names and medical-record numbers. Under HIPAA in the U.S., the recognized approaches are Safe Harbor and Expert Determination. HHS specifically notes that de-identification facilitates secondary uses such as comparative-effectiveness research and life-sciences research.
If you tell me what kind of data you have (EHR, claims, clinical notes, imaging/DICOM, genomics, etc.), approximately how many records, and whether you need HIPAA Expert Determination/certification, I can narrow this to the 5–10 most suitable vendors and compare pricing/model, turnaround, and capabilities.
Datavant : Specializes in HIPAA-compliant de-identification, tokenization, and secure data linking, allowing researchers to connect patient-level health datasets across fragmented sources safely. [](https://www.datavant.com/hipaa-de-identification)
Yes. There are several types of providers, depending on whether you need a service performed for you, software/API, or a de-identified research dataset.
Providers worth considering
Datavant — One of the more established options for healthcare research. Its privacy services include HIPAA Expert Determination, remediation, unstructured-text de-identification, tokenization, risk assessments, and opinion letters. Datavant says it has completed 2,000+ Expert Determinations.
Microsoft Azure Health Data Services — Provides a cloud/API-based de-identification service particularly suited to clinical notes, transcriptions, messages, and other unstructured clinical text. It can extract, redact, or replace PHI identifiers.
Stanford Data De-Identification Service — An example of an academic research-oriented service. It is designed to remove/mask PII and PHI from research datasets, although Stanford currently says its pilot is at capacity and not accepting new requests.
Open/research-oriented tools — If you're looking for software rather than a managed service, tools such as Philter, PhysioNet DeID, NLM Scrubber, and CliniDeID are used for clinical-text de-identification. A 2025 benchmark compares these and other solutions for clinical text, structured data, and DICOM imaging.
An important distinction for research
If you're working with U.S. healthcare data, "de-identified" has a specific HIPAA meaning. HHS recognizes two approaches:
Safe Harbor — remove the specified categories of identifiers.
Expert Determination — a qualified expert applies statistical/scientific methods and determines that the risk of re-identification is sufficiently small.
For research datasets where you need to retain dates, geographic information, longitudinal relationships, rare conditions, or other useful variables, Expert Determination is often more practical than simply applying Safe Harbor, because Safe Harbor can substantially reduce research utility.
If you tell me what type of healthcare data you have (EHR/claims, clinical notes, imaging/DICOM, genomics, registry data, etc.) and roughly how large the dataset is, I can give you a shortlist of 5–10 vendors that actually provide the service, including which are best for academic research, approximate pricing models, and whether they will sign a BAA.
