REDACT THAT ****!
We build open source redaction software for PII and PHI and help users integrate our open source software into their tech stacks.
Self-managed open source redaction
Philter is open source software that redacts and anonymizes PII and PHI.
Philter runs in your cloud, and your data never leaves your cloud. Philter never sends your data to any third-party.
Philter is for system integrators who are comfortable implementing an API.
Core redaction library
Phileas is an open source redaction library that powers our other redaction software.
Phileas is a high capable redaction library in use by small and large organizations.
Licensed under the Apache License, version 2, you are welcome to use Phileas directly in your applications.
Check it out on GitHub to learn more.
Redaction is so much more than finding words and replacing them with asterisks. Keeping anonymized values consistent across a group of documents? Only redacting zip codes that meet a population threshold? Encrypting data instead of just masking it? Our software is built to handle all of this and more.
