### How-tos

How-to Policy authoring

#### [Authoring Redaction Policies with PhiSQL](https://philterd.ai/guides/authoring-redaction-policies-with-phisql/)

PhiSQL is a readable query language that compiles to a Phileas redaction policy. An introduction to the syntax and how it maps to the policy JSON.

How-to Policy authoring

#### [Redacting National and Financial ID Numbers](https://philterd.ai/guides/redacting-national-and-financial-id-numbers/)

A how-to for redacting national and financial IDs (SIN, CPF, DNI, IBAN, BIC, and more) with checksum-validated patterns that reject look-alikes.

How-to Integrations

#### [Redacting PII in Apache Kafka](https://philterd.ai/guides/redacting-pii-in-apache-kafka/)

Redact PII and PHI in Apache Kafka with the philter-kafka-connect Single Message Transform, on source, sink, or MirrorMaker connectors.

How-to Integrations

#### [Redacting PII in Logs with log4j2 and logback](https://philterd.ai/guides/redacting-pii-in-logs-with-log4j2-and-logback/)

How to redact PII from Java logs before they are written, with a Phileas-backed log4j2 rewrite policy and a logback converter, recursion guard included.

How-to Integrations

#### [Redacting PII in Spark and Databricks](https://philterd.ai/guides/redacting-pii-in-spark-and-databricks/)

Redact PII column by column in Apache Spark and Databricks with a Phileas UDF: a verified PySpark example, plus the performance tradeoffs to plan for.

How-to Integrations

#### [Redacting PII in Trino with the Phileas Connector](https://philterd.ai/guides/redacting-pii-in-trino-with-the-phileas-connector/)

How to install the open source Phileas connector for Trino, configure a redaction policy, and mask PII column by column in SQL, with a runnable demo.

### Reference

Reference Policy authoring

#### [The Phileas redaction policy schema](https://philterd.ai/guides/redaction-policy-schema/)

What a redaction policy is, how the JSON schema is structured, and how to use it to control exactly which PII is detected and how each type is redacted.

### Concepts

Concept Self-hosting

#### [Self-Hosted PII Detection on Your Own Hardware](https://philterd.ai/guides/self-hosted-pii-detection-on-your-own-hardware/)

Run PII detection entirely inside your own boundary: serve the models with PhEye, embed Phileas, or run local ONNX inference, with no data egress.

Concept Detection

#### [Span Disambiguation: What It Does and When to Enable It](https://philterd.ai/guides/span-disambiguation/)

When two Phileas filters claim the same text with different types, span disambiguation picks one. When it helps, what it costs, and how to run it.
