Privace.ai vs Philter
A self-hosted, open-source REST API that redacts PII and PHI at scale in your own VPC.
What Philter does
Philter (by Philterd) is a turnkey, self-hosted redaction API in production since 2017. It redacts PII and PHI from text at scale inside your own cloud or data center, is multi-cloud and on-prem capable, and uses configurable policies (filter profiles) with custom dictionaries, ignore lists and checksum-validated identifiers — a strong fit for healthcare, finance and government batch workloads.
How Privace.ai differs
Philter excels at server-side, self-hosted batch redaction. Privace.ai targets interactive public-LLM use: a browser extension that intercepts prompts in-tab, restores originals in the answer, enforces admin sector policies, scores output with an LLM-as-a-Judge and brokers strict BYOK — a managed GCP-native gateway rather than a redaction API you run.
Privace.ai vs Philter: capability comparison
A fair, side-by-side look at the seven dimensions that define an LLM redaction gateway.
Reversible redaction — restore originals in the LLM response
Admin-owned sector PII / PHI / PCI libraries
In-LLM-input interception (browser extension, before submit)
Strict BYOK — your own LLM key, keys never shared
Single-perimeter, GCP-native data sovereignty
LLM-as-a-Judge output scoring
Token-only, fully auditable trail
Comparison reflects publicly documented capabilities at time of writing and each product's primary design intent; vendors evolve quickly — verify specifics for your use case.
