PII Detection
Identify personally identifiable information in text, documents, and data streams before they reach an AI model.
Privacy infrastructure for AI.
FastPII is an AI data security and privacy platform that helps developers detect, validate, protect, mask, redact, and control sensitive information before or while it interacts with AI systems - with PII detection, deterministic identifier validation, an AI gateway, policy enforcement, and developer SDKs.

FastPII
What it does
Protect sensitive data before AI touches it.
AI systems are only as safe as the data they see. FastPII gives developers and organizations the infrastructure to make sure sensitive information is detected, protected, and controlled - before or while it interacts with AI.
From PII detection to policy enforcement to an AI gateway that mediates every interaction, FastPII makes secure AI practical rather than aspirational.
Capabilities
What FastPII includes.
The components that let developers build AI systems that handle sensitive data responsibly.
PII Protection
Mask, redact, and protect sensitive fields so AI systems never see data they shouldn't.
Deterministic Identifier Validation
Validate identifiers deterministically - know exactly what's sensitive and what isn't, every time.
AI Gateway
A gateway that mediates every interaction between your application and AI models - inspecting, filtering, and enforcing policy.
Policy Enforcement
Define what's allowed and what isn't. FastPII enforces your policies on every request, consistently.
Developer SDKs
SDKs that let developers integrate PII protection into their applications without becoming security experts.
Secure AI interactions
Make AI safe for sensitive data.
Whether you're building with AI or operating systems that handle PII, FastPII gives you the infrastructure to do it responsibly.
