The same rule processor runs twice: once over the request, once over the answer. Every match returns three things — the action, the condition that fired, and a confidence — and that triple is what lands in the event record an examiner will ask for.

Where a financial assistant is exposed

  1. 01

    Cardholder Data Controls

    Controls that support your PCI DSS obligations: automatic detection and redaction of card numbers, CVVs, and financial account data.

  2. 02

    Financial PII Protection

    Detect and protect account numbers, routing numbers, SSNs, and other sensitive financial identifiers before they reach your LLM.

  3. 03

    Fraud Detection

    Identify suspicious patterns in user interactions. Block social engineering attempts and manipulation tactics targeting financial systems.

  4. 04

    Transaction Guardrails

    Enforce limits on AI-assisted transactions. Require human approval for high-value operations and flag unusual activity.

  5. 05

    Disclaimer and Advice Policies

    Write an output policy that blocks an answer offering specific investment guidance without the disclaimer your compliance team requires. PromptGuard evaluates the response against your rule; it does not rewrite it.

  6. 06

    Audit Trail for Regulators

    Complete logging of all AI interactions. Export-ready reports for regulatory audits and compliance reviews.

Why PromptGuard for fintech?

  • Purpose-built PCI-DSS controls
  • Financial PII detection out of the box
  • Transaction-aware guardrails
  • Regulatory audit support
  • Audit-ready logging

Securing financial AI assistants

python
from promptguard import PromptGuard

pg = PromptGuard(
    api_key="your-api-key",
    project_id="banking-assistant"
)

# Configure financial-specific protections
pg.configure({
    "pii_detection": {
        "enabled": True,
        "types": ["credit_card", "ssn", "account_number", "routing_number"],
        "action": "redact"  # or "block"
    },
    "financial_guardrails": {
        "require_disclaimer": True,
        "block_investment_advice": True,
        "transaction_limit": 10000,
        "require_approval_above": 5000
    }
})

# Your AI interactions are now protected
response = pg.guard(
    prompt=user_message,
    context={"user_id": user.id, "account_type": "retail"}
)
