Secure Every AI Interaction
FastPII is the AI Data Security Platform that detects, protects, governs, and audits sensitive data before it reaches any LLM.

Secure the flow
Deterministic inspection across every prompt and response.
LLM Providers
Protected delivery
See the risk path and the protected path in one scroll
The before-and-after diptych keeps the anxiety and the answer together: direct LLM delivery exposes sensitive records, while FastPII inspects and protects them before they leave your stack.
Without FastPII
Sensitive data goes directly to LLM
With FastPII
Data is secured before reaching any LLM
[REDACTED] → Secure → LLM
Privacy infrastructure built for AI traffic
These four pillars replace the heavier platform tour while keeping the same design language and trust posture.
AI-Native
Built for prompts, RAG payloads, tool calls, and agent workflows instead of generic text pipelines.
Works where model traffic actually moves.
Privacy-First
Sensitive values are identified before they leave your stack so teams can redact, mask, and route safely.
Protection happens before provider delivery.
Validation-Driven
Country-aware identifiers and structured checks reduce false positives in production review flows.
European records stay precise under messy formatting.
Dev-Friendly
FastPII fits into SDK, API, and framework-based stacks without forcing a platform rewrite.
Start in code, graduate into gateway control.
Install it, detect it, anonymize it, integrate it
A single tabbed block keeps the implementation proof near the homepage narrative without restoring the old developer-experience section.

# or call the hosted BFF from your appCzech Advantage
Built globally. Proven on Czech records first.
FastPII started where structured privacy gets hard: Czech identifiers, local formatting, and production-grade validation. That foundation now carries into broader European AI data protection.
Use Cases
Designed for teams handling sensitive AI inputs
Build privacy into your AI stack
Start with the open-source FastPII foundation, then move into the live app when you are ready to govern production AI traffic.
