Why healthcare teams pick Philter

HIPAA Safe Harbor, end-to-end

All 18 protected identifiers under 45 CFR § 164.514 - from names and SSNs to dates, biometric IDs, and full-face photos - handled in a single configurable pipeline. See the blueprint.

Clinical models, not generic NER

Specialized NLP lenses trained on clinical text - recognizes medical terminology, drug names, and clinical context, not just emails and phone numbers. Why this matters.

BAA stays clean

PHI never leaves your VPC - no third-party API endpoints, no multi-tenant service, no new vendor BAA to sign. Your existing AWS / GCP / Azure BAA still covers everything.

Audit-ready by design

Stateless processing, immutable policy versioning, structured audit logs, and a benchmarking harness (Philter Scope) that scores every policy change against precision and recall on gold-standard datasets.

Sized for clinical-pipeline volume

Bulk EHR exports, real-time clinical NLP at the message bus, or HL7 / FHIR streams - same engine, horizontally scalable. Deployment patterns cover the common shapes.

Open source - review the code, not the marketing

Your security and clinical-informatics teams can audit the actual logic, fork it, or run it air-gapped - no closed-source ML, no “trust our HIPAA black box.”

What we’ll cover on the call

Your current pipeline: where PHI flows, what’s already redacted, what’s been deferred.
HIPAA Safe Harbor coverage: a real gap analysis against all 18 identifiers, not a generic checklist.
Deployment shape: VPC architecture, BAA implications, integration points (HL7, FHIR, CSV exports, S3, Kafka).
Cost picture: per-instance economics vs. per-character SaaS APIs at your actual volume. Most teams cross the break-even sooner than they expect.
A concrete next step: marketplace deploy, embedded engineering, or a no-go - whichever fits.

No NDA needed for the conversation. We won’t ask you to send sample data - we’ll walk you through how Philter would handle the patterns you describe.
