Intro call
A 30-minute call about what you need to protect and which regulations apply. No pitch, and if the open source toolkit alone is enough, we will say so.
Consulting
PII redaction, designed for your stack. You own it.
Bring in the team that built the software. We assess what you need and deliver an implementation plan, then either build it inside your own cloud or hand it to your engineers to build. Either way you end up with a system you own outright.
Our engagement process
Four steps, from the first call to a system you own.
Discovery
A few working sessions on your data, systems, and obligations. You keep the assessment and the implementation plan, whether or not we build it.
Implementation
We build the plan inside your own cloud, so your data never leaves your perimeter. Your engineers can work alongside us.
Handoff
You get the policies, the configuration, and a runbook to run it without us. We are here when you want us back.

Selected work
A few engagements we have delivered.
Bankruptcy filing redaction for a law firm
A law firm with no in-house engineers needed PII removed from federal bankruptcy filings under Rule 9037. We designed the redaction, stood up the AWS deployment, and handed back a system that redacts documents automatically as staff save them.
Read the case study →Multilingual patient chatbot
Embedded real-time PII redaction into a bilingual (English/French) patient chatbot so sensitive information is stripped before messages reach human agents or analytics storage.
Read the case study →EHR-to-database data pipeline
Deployed Philter inside an AWS data pipeline to de-identify clinical narrative text flowing from an EHR into an analytics database, enabling research access without HIPAA restrictions.
Read the case study →How we plug in
A few common ways we plug in, from a full build to training models on your data. They are not the only shapes an engagement can take.
Setup and handoff
We stand up PII redaction in your own cloud, configure and validate it on your data, then hand you a running system you own. No in-house engineering team required. If you would rather build from the Discovery plan yourself, that works too.
Privacy architecture
We design end-to-end PII protection for your data and AI workloads: data flows, redaction layers, audit trails, and the guardrails that keep generative-AI features aligned with HIPAA, GDPR, and CCPA.
Custom detection models
Off-the-shelf models miss the identifiers that matter most in your domain. We train specialized PII and PHI detectors on your data, measured against precision and recall you can put in front of an auditor.
