Strac is a capable SaaS DLP with strong redaction UX across email, ticketing, and AI surfaces — but like other cloud DLPs, its published architecture inspects content in Strac's cloud. For a buyer whose problem is regulated data leaving the network, the inspection path is the exposure.
| Dimension | HoundShield | Strac |
|---|---|---|
| Where content is scanned | Locally, inside your network (Mode B/C) | In Strac's cloud |
| CUI/PHI leaves your boundary to be checked? | No | Yes — sent to their service to scan |
| CMMC / NIST 800-171 evidence PDF | $499 one-time, control-mapped | Not a deliverable |
| SaaS app coverage beyond AI | AI endpoints via proxy | Email, Slack, Zendesk, storage, and more |
| Redaction UX | Block/quarantine with audit trail | Inline masking of the sensitive element |
| Air-gapped deployment | Yes (Mode C) | No (cloud-native) |

Strac provides SaaS and endpoint DLP with automatic detection and redaction of sensitive data (PII, PHI, payment data) across tools like email, Slack, Zendesk, and generative AI apps. Content is scanned by Strac's cloud service, which then redacts or blocks per policy.
HoundShield Mode B (self-hosted Docker) inspects every AI-bound prompt on your own infrastructure in <10ms. A cloud DLP must receive your content to scan it — for CUI under DFARS 7012, that transit is the exposure you were trying to prevent.
The $499 CMMC AI Risk Assessment maps every prompt event to NIST 800-171 Rev 2 controls in a SHA-256-signed PDF — a deliverable your assessor reads. General DLP dashboards don't translate to assessor evidence.
Any OpenAI-compatible endpoint — ChatGPT, Copilot, Claude, Gemini — is covered by one URL change at the network level, rather than per-app SaaS integrations.
Mode C runs with no external connectivity at all. Cloud-native DLP architectures cannot follow you into an isolated network.
Who this matters most for: Defense subcontractors and healthcare privacy officers whose core requirement is that regulated content never transits a vendor cloud — and who need assessor-grade evidence, not just prevention.
HoundShield scans prompts locally in under 10ms. That CUI-safe property holds only when the scanner runs inside your own boundary. Pick the deployment mode that matches your data:
A · Hosted trial
On Vercel — not FedRAMP-authorized. Demo and non-CUI evaluation only.
B · Self-hosted Docker
Your own infrastructure. CUI-safe — prompt content never leaves your boundary. Right for CUI-handling contractors.
C · Air-gapped
Isolated network. CUI-safe. For enterprise / IL-5+ environments.
