PII Redaction for Government
Redact personal information from records before they are released, inside your own environment or on a single PC. FOIA expects each deletion to be marked with the exemption behind it, such as (b)(6) for personal privacy, at the place in the record where it was made when that is technically feasible.
For agencies and departments
What Philterd does with public records
A reviewer makes the call
Automated detection proposes the redactions. In Philter Workspace, a reviewer accepts or overrides each one with a structured exemption code, such as (b)(6) or (b)(7)(C), and every decision is recorded with the reason behind it.
Open source you can inspect
The software is open source under the Apache license. Your security team can read the code, and you can explain in writing how a redaction decision was made.

- Deploy Philter inside your boundary, from your cloud’s marketplace or on your own servers. See the air-gapped deployment walkthrough for networks with no internet access.
- Start from a policy in the library, and add patterns for your own case, report, and permit number formats.
- Measure it on records you have already released. Compare the policy’s output with your past redactions using Philter Scope, and adjust it where your records officers would have decided differently.
- Add Philter Workspace when releases need a reviewer to sign off on each redaction with an exemption code.
