Redaction policies

A redaction policy is the JSON file that tells Philter, Phileas, and Philter Desktop which PII to look for and what to do with each match. A policy from the library is a starting point, not a finished control: measure it on your own documents before you rely on it.

  • Policy library

    Ready-to-use policies for HIPAA, PCI DSS, FRBP 9037, FERPA, GLBA, AI training data, and more, free under the Apache License.

    Browse the library
  • Write your first policy

    A hands-on walkthrough from an empty file to a working policy: detect a type, change how it is redacted, and handle false positives.

    Start the walkthrough
  • Policy schema reference

    What each part of a policy does, how filters and strategies fit together, and the JSON schema every policy follows.

    Read the reference
  • Other ways to write one

    Build a policy in a form with the Redaction Policy Editor, or write it as readable PhiSQL that compiles to the same JSON.

    Write a policy in PhiSQL

Community support

For everyone using the open source toolkit

Development happens in public. When you file an issue, you reach the engineers who wrote the code, with no support-tier triage in between.

  • Documentation Start with your product's support page above, which collects its guides, documentation, and issue tracker. The knowledge base covers how-tos and troubleshooting across the toolkit, and products and packages links every product's docs. If something is wrong or missing, open an issue and we will fix it.
  • Issue trackers Report bugs, request features, and ask questions in each product's repository under github.com/philterd. We triage weekly.

Free to use, with no support contract required.
