PII Firewall Edge is a zero-trust privacy API that redacts 150+ types of personally identifiable information before sending data to AI/LLM services.
Key Features: โ 150+ PII types (SSN, emails, phones, passports, API keys, JWTs, etc.) โ Sub 10ms edge latency (Cloudflare Workers) โ Zero storage, zero logs, zero AI โ Two modes: /fast (heuristic pre-scan) and /deep (name detection)
Pricing: โข FREE: 500 calls/month โข PRO: $5/mo (5K calls) โข ULTRA: $10/mo (20K calls) โข MEGA: $25/mo (75K calls)
Competitors: Amazon Comprehend PII, Google Cloud DLP

PII Firewall EdgePII Firewall Edge's answer:
PII Firewall Edge is built on a zero-AI, zero-storage, zero-log architecture - a fundamentally different approach to PII detection.
Key differentiators:
No AI/ML involved: Unlike competitors that use machine learning (and send your data to their models), we use deterministic regex patterns with cryptographic checksums (Luhn, Verhoeff, mod-97). Your data never trains anyone's model.
Edge processing: Runs on Cloudflare's global network (300+ locations) with sub-10ms latency. No cold starts, no queuing.
Zero persistence: Data flows in, gets sanitized, flows out. Nothing is stored, logged, or persisted. Ever.
150+ PII types: From SSN and AADHAAR to API keys, JWTs, crypto wallets, and international IDs across 20+ countries.
Developer-first pricing: $5/mo PRO tier vs $500+/mo enterprise alternatives. Free tier included (500 calls/month).
The result: military grade PII redaction without the enterprise complexity or AI black boxes.
PII Firewall Edge's answer:
vs Amazon Comprehend PII:
10x faster: Sub-10ms vs 100-200ms typical Comprehend latency
10x cheaper: $5/mo vs pay-per-character pricing that scales to $500+/mo
No AWS lock-in: Works anywhere via simple REST API
No AI: Comprehend uses ML - your data trains their models. We use deterministic patterns.
More PII types: 150+ vs Comprehend's ~20 categories
vs Google Cloud DLP:
No GCP required: DLP requires Google Cloud infrastructure. We're platform-agnostic.
Simpler integration: One API call vs complex DLP template configuration
Transparent pricing: Flat monthly fee vs inspection unit pricing that's hard to predict
Zero-log guarantee: DLP can log to Cloud Logging. We never store anything.
Faster deployment: npm install + one API call vs GCP project setup, IAM, service accounts
The bottom line: Enterprise solutions assume you have enterprise budgets and infrastructure. PII Firewall Edge gives indie developers and startups the same protection at 1/100th the cost, with a 10x simpler integration.
PII Firewall Edge's answer:
Core stack:
Cloudflare Workers: Serverless edge compute for sub-10ms global latency. No cold starts, automatic scaling to millions of requests.
JavaScript (V8 isolates): The detection engine runs in Cloudflare's V8 isolates - secure, sandboxed, memory-limited by design.
Deterministic regex + checksums: No ML/AI. We use hand-crafted regex patterns validated with cryptographic checksums:
RapidAPI: API management, authentication, rate limiting, and developer portal.
Zero-dependency architecture: No external databases, no ML model calls, no third-party logging. The entire system fits in a single Cloudflare Worker.
Why this stack? Edge computing ensures data never leaves the region. No AI means no training on customer data. No dependencies means no supply chain risk.
PII Firewall Edge's answer:
Primary audiences:
Indie hackers & solo developers building AI-powered products who need to sanitize user input before sending to OpenAI, Claude, or other LLMs. They need something that "just works" without enterprise complexity.
Early-stage startups (Seed to Series A) adding AI features to existing products. They care about compliance (GDPR, HIPAA, CCPA) but can't afford $500+/mo enterprise contracts or dedicated security engineers.
Mid-size B2B companies processing customer data through AI pipelines. They need audit-friendly, deterministic PII detection - not AI black boxes they can't explain to compliance teams.
Privacy-conscious developers who refuse to send user data to yet another AI service for "analysis." They want zero-trust architecture where data never persists.
Common thread: Teams that move fast but take privacy seriously. They want enterprise-grade security without enterprise-grade budgets or complexity.
PII Firewall Edge's answer:
I was shipping an AI feature for a client project when I had a terrifying realization: every customer message was going straight to OpenAI - names, emails, phone numbers, all of it. No sanitization. No audit trail. Just hope.
I looked for solutions:
Enterprise tools (Google DLP, Amazon Comprehend): $500+/mo, complex setup, and they use AI themselves - so I'd be sending PII to another third party.
Open-source options (Presidio): Required self-hosting, GPU infrastructure, and ongoing maintenance.
Nothing in between: No simple, affordable API that "just worked."
So I built what I wished existed: a sub-10ms edge API that strips 150+ PII types using deterministic patterns - no AI, no storage, no logs. Priced at $5/mo because privacy shouldn't be a luxury only enterprises can afford.
The name "Firewall Edge" reflects the architecture: it's a firewall for PII, running at the edge of the network, before sensitive data ever reaches third-party APIs.
PII Firewall Edge's answer:
We're an early-stage product focused on indie developers and startups, so we don't have Fortune 500 logos (yet!).
Current user base: - Solo developers building AI-powered SaaS products - Early-stage startups (pre-seed to Series A) adding LLM features - Privacy-conscious developers who prioritize zero-log architecture
Use cases we're seeing: - Sanitizing user input before OpenAI/Claude API calls - Redacting PII from customer support logs before AI analysis - Compliance preprocessing for GDPR/HIPAA-regulated applications - Protecting API keys and secrets in developer tool outputs
We're building in public and prioritizing developer experience over enterprise sales. Our "biggest customers" are the indie hackers shipping AI products who can't afford a data breach - but also can't afford $500/mo enterprise tools.

Hmmm... I largely use https://github.com/bailey27/cppcryptfs with dropbox? This would essentially eliminate any possibility of violating any terms of service as far as I can tell? I'm not too comfortable putting any files on dropbox without some sort of encryption fwiw, I've found that cppcryptfs is one of the better implementations of that sort though most (if not all) use the same library which seems to choke on... - Source: Hacker News / about 4 years ago

Not sure if you can use Google Drive as a folder (I can do that in Linux). If you can then cppcryptfs (Windows version of gocryptfs) would work. I use it in Linux for Dropbox and GDrive. Source: over 4 years ago
