How it works

Automated PII redaction with tamper-proof audit trails

1

Request enters gateway

Your app sends prompts through Bastio before they reach the LLM provider.

2

PII automatically redacted

Credit card numbers, SSNs, bank accounts, and other financial data are masked in real-time.

3

Compliant response returned

Clean, audited response with tamper-proof logging for your next compliance review.
