PII Firewall Edge – Prevent PII leaks to LLMs with one API call

Summary: PII Firewall Edge is a privacy API that sanitizes text containing over 150 types of personally identifiable information (PII) before it reaches large language models (LLMs). It operates on Cloudflare’s edge network with sub-10ms latency, using regex and validation without storing or logging data.

What it does

It detects and removes PII such as SSNs, passport numbers, and API keys from text via a single API call processed at the edge, ensuring no data is stored or sent to AI models.

Who it's for

Designed for indie hackers, startups, and compliance teams needing fast, affordable protection against data leaks to LLMs.

Why it matters

It prevents sensitive user data from being exposed during API calls to AI services, reducing compliance risks and data breaches.
