## Redaction policies

A redaction policy is the JSON file that tells [Philter](https://philterd.ai/philter/), [Phileas](https://philterd.ai/phileas/), and [Philter Desktop](https://philterd.ai/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](https://philterd.ai/guides/measure-redaction-accuracy-with-philter-scope/) 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](https://philterd.ai/policies/)
- ### 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](https://philterd.ai/guides/writing-your-first-redaction-policy/)
- ### 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](https://philterd.ai/guides/redaction-policy-schema/)
- ### Other ways to write one
   
   Build a policy in a form with the [Redaction Policy Editor](https://philterd.ai/redaction-policy-editor/), or write it as readable [PhiSQL](https://philterd.ai/phisql/) that compiles to the same JSON.

## Ways to get support

Free · Open source

## 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](https://philterd.ai/guides/) covers how-tos and troubleshooting across the toolkit, and [products and packages](https://philterd.ai/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](https://github.com/philterd). We triage weekly.

Free to use, with no support contract required.
