Does this shrink our PCI scope?

It stops cardholder data reaching external models, reducing your AI tools' exposure. It's a strong control, not a scope guarantee — confirm treatment with your QSA.

How does it protect privilege?

Privileged content is caught locally and never disclosed to a third-party model, avoiding an inadvertent waiver.

Can compliance review what was blocked?

Yes. Every decision is written to a signed, timestamped audit trail you can export for SOC 2, PCI DSS and bar-association reviews.

Does it work with our existing AI tools?

Yes — any OpenAI-compatible research or drafting tool routes through HoundShield with a single base-URL change.

Privileged and cardholder data shouldn't train someone else's model.

Lawyers and analysts paste privileged matters, deal terms and account data into AI to move faster. HoundShield scans every prompt locally and blocks privileged, PII and PCI data before it leaves — protecting attorney-client privilege and your PCI scope at the same time.
