Secure every AI interaction
FastPII brings Detection Engine, Protection Engine, AI Gateway, Policy Engine, and Audit into one operating layer so teams can detect, protect, govern, and audit AI traffic without stitching together point tools.
Integrated modules
One control plane for AI data security
Core verbs
Detect, protect, govern, and audit.
Gateway path
OpenAI-compatible proxy with streaming and BYOK.
Five modules, one operating model
Each module handles a different control point, but they work as one system across prompt, response, agent, and workspace traffic.
Detect
Detection Engine
Run 33 detectors across Czechia, Poland, Germany, and France with checksum-aware validation for high-signal identifier coverage.
Protect
Protection Engine
Apply redact, mask, anonymise, or hash before any sensitive data reaches a model, log, or downstream workflow.
Govern
Policy Engine
Match policies by entity type, country, provider, model, workspace, confidence, and sensitivity, then enforce the right action.
Audit
Audit
Capture 20+ fields per event, export JSON or CSV, and generate review-ready report templates for compliance teams.
Connect
AI Gateway
Route OpenAI-compatible traffic through /v1/chat/completions with streaming, provider routing, BYOK, and central policy checks.
How FastPII moves through every AI request
The platform is designed to sit in the path of live AI traffic so controls happen before data leaves your application boundary.
Step 1
Application request enters
Application request enters FastPII
Step 2
Detection Engine identifies
Detection Engine identifies sensitive data
Step 3
Protection Engine transforms
Protection Engine transforms what should not leave the organisation
Step 4
Policy Engine decides
Policy Engine decides ALLOW, WARN, MASK, BLOCK, ESCALATE, LOG, or QUARANTINE
Step 5
AI Gateway forwards
AI Gateway forwards the safe payload to the selected provider
Step 6
Audit records the
Audit records the decision and exportable evidence
Start with one use case, expand to every model path
Teams usually begin with prompt inspection, then roll out the same policies to chat, agents, SDK workloads, and central gateway traffic.
