Why piisafe.eu Stands Out

🌐 Web-First Design

Only tool purpose-built for website scanning. Discovers pages via sitemap.xml, automatically chunks 50KB+ content, tracks findings per-page. Competitors focus on documents/APIs; we specialize in web.

🏆 Most Entity Types

320+ entity types via cloak.business (SSN, IBAN, credit cards, driver's licenses, tax IDs) vs. Presidio's 50, Strac's 120, or PII Tools' scattered coverage.

🌍 48 Languages

Only scanner with region-specific patterns for GDPR (EU), HIPAA (US), PCI-DSS (payments), CCPA (CA), and country-specific formats (IBAN, NINO, Steuer-ID, DNI, etc.).

🔒 Zero-Knowledge

Results stream directly to your browser. No server-side database, no logs, no admin access. Even our team cannot see your scan data—it's architecture, not marketing.

💰 Completely Free

No credit card, no registration, no freemium limits. Full access to 320+ entities, all 48 languages, unlimited scans. PII Tools costs $800+/mo; PII Crawler costs $497; we cost $0.

⚡ Instant Setup

No installation, no Docker, no Python setup. Open scanner.html in a browser and start scanning. Competitors require 10-30 minutes of DevOps work; we take 10 seconds.

📊 Dual APIs

Choose cloak.business (320+ entities) or anonym.legal (285+ entities, MCP Server). Independent providers = vendor lock-in prevention. Competitors lock you into single platform.

📈 Automatic Chunking

Large pages >50KB? Automatically splits into chunks, analyzes all content, aggregates findings. Competitors truncate or error; we analyze 100% of your site.

Comparison Questions

Can I use piisafe.eu offline like PII Crawler? →

No. piisafe.eu is web-based and requires an internet connection. If you need offline, air-gapped scanning, PII Crawler ($497) is the right choice. For maximum privacy with internet, piisafe.eu's zero-knowledge architecture ensures data never touches our servers.

How does piisafe.eu compare to Microsoft Presidio for developers? →

Presidio is a Python library—great for custom training and integration into CI/CD. piisafe.eu is web-first and REST API-based. Choose Presidio if you need to train custom models; choose piisafe.eu for quick website audits without setup. They complement each other.

Why is piisafe.eu free while others charge? →

piisafe.eu is part of the curta.solutions PII ecosystem. We offer it free to establish market presence and gather feedback. The API providers (cloak.business, anonym.legal) are the revenue model—we're the free interface. Other tools charge because scanning is their only product.

What if I need document scanning, not just web? →

piisafe.eu is web-only. For documents, consider: anonym.plus (desktop app, 200+ entities), PII Tools (enterprise, 400+ entities), or Presidio (open-source, Python). All three handle PDFs, Word, Excel, and other file formats.

Is piisafe.eu truly zero-knowledge compared to Strac? →

Yes. piisafe.eu's zero-knowledge means data never leaves your browser—results stream directly to your local machine. Strac is SaaS DLP, meaning your data is processed on their servers and they have access. Different architectures for different needs: piisafe for privacy, Strac for enterprise policy enforcement.
