1.1 Million Calls, None of Them Leaving the County
One of the largest counties in California, serving over 3 million residents, wanted to analyse its health and human services call recordings to understand caller satisfaction. The recordings were full of PII, and California law meant they could not leave the county's possession to be analysed.
The Constraint
The county wanted to use an experience management platform to analyse call quality. The recordings contained names, phone numbers and Social Security numbers.
Under CCPA and CPRA, those recordings could not be shared with third-party providers outside the state. The only route forward was to redact every recording before it left county hands.
That set two hard requirements, and most redaction tools fail at least one of them:
- Volume. The county receives 1.1 million call recordings a year. Any per-file, operator-driven workflow was arithmetically impossible.
- Locality. The software had to run inside the county's own four walls, so no PII crossed the jurisdiction at any point — including during processing.
A cloud redaction service fails the second requirement by definition, because the content leaves to be processed.
What Was Deployed
Redactor was deployed into the county's own private cloud — the same environment already holding the call recordings. Processing happened where the data already lived, so nothing crossed the jurisdictional boundary.
Bulk audio redaction handled the volume: queue-based processing running unattended against the archive rather than one file at a time, with spoken PII detected and removed automatically.
The redacted recordings could then be shared with the analytics provider without infringing state privacy law, while the originals stayed in county custody.
Results
- 1.1 million recordings a year processed through bulk audio redaction
- No PII left the jurisdiction, because processing ran inside the county's own infrastructure
- The analytics programme went ahead, which without redaction was not legally possible
Why It Worked
The deciding factor was not detection quality. It was where the software could run.
For a jurisdiction-bound workload the question is whether content crosses the boundary at all, and a hosted redaction API answers that question the wrong way. Redactor runs in shared SaaS, dedicated cloud, private cloud, on-premises and fully air-gapped, with the same engine in each.
