THE ASYMMETRIC ADVANTAGE

Every other tool makes
the problem worse.

Nightfall, Strac, and Microsoft Purview all send your CUI to their cloud to scan it. That's itself a DFARS 7012 spill. HoundShield scans locally. Nothing leaves Jordan's network.

Frequently asked

No. HoundShield runs entirely on your infrastructure. The scanning engine, detection patterns, and audit logs all stay local. Only a license key hash and prompt count (no content) go external for billing.

Under 10 minutes for most organizations. Change one environment variable to point AI tools at your HoundShield endpoint. Docker deployment is 3 commands. No agents, no firewall rules, no code changes.

Any tool using an OpenAI-compatible API: ChatGPT, Copilot, Claude, Gemini, Cursor, Codeium, and open-source models. It operates at the network layer, so it's model-agnostic.

HoundShield maps all 110 NIST 800-171 Rev 2 controls and generates C3PAO-ready PDF evidence. Because it's local-only, CUI never crosses your control boundary — satisfying NIST 3.13.1 and supporting CMMC Level 2 certification.

The prompt is blocked and the user receives a policy violation message. A tamper-proof, SHA-256 signed log entry is created with the timestamp, matched pattern, and affected framework. Webhook notifications are available on Pro and above.
