WitnessAI is a serious enterprise AI security and governance platform with deep observability and a federal-friendly channel (it sells through Carahsoft and has heavyweight security leadership on its board). For a 50–500 person contractor, the gap is fit: enterprise platforms mean enterprise procurement, enterprise pricing, and enterprise deployment timelines. HoundShield is built for the buyer who needs enforcement this week and assessor evidence this month.
| Dimension | HoundShield | WitnessAI |
|---|---|---|
| Target buyer | 5–500 person DIB / healthcare / legal | Large enterprise and federal |
| Time to deployment | Minutes (self-hosted Docker) | Enterprise rollout cycle |
| Entry price | $499 one-time assessment, published plans | Enterprise-quoted |
| CMMC / NIST 800-171 evidence PDF | Yes — control-mapped, signed | Governance reporting, not a CMMC assessment artifact |
| AI governance breadth at enterprise scale | Focused prompt firewall + audit | Broad observability and governance platform |
| Federal channel presence | Direct + RPO/MSP partners | Established Carahsoft channel |

WitnessAI provides an enterprise platform for observing, governing, and securing employee AI usage — visibility into which AI apps are in use, policy enforcement, and protection against prompt-level risks — sold primarily to large enterprises and public-sector buyers through channel partners.
HoundShield deploys as self-hosted Docker (Mode B) in minutes and starts at a $499 one-time assessment — no enterprise sales cycle, no platform rollout. The DIB mid-market can't wait a procurement quarter for AI controls.
The $499 CMMC AI Risk Assessment runs two weeks in your environment and produces a SHA-256-signed PDF mapping every AI prompt event to NIST 800-171 Rev 2 — an artifact you hand your C3PAO, not a dashboard you interpret.
The report is $499. Plans are published on the pricing page. Enterprise platforms are quoted — and quotes gate SMBs out.
In Mode B, prompt scanning happens entirely on your infrastructure; in Mode C it runs air-gapped. Nothing about your AI usage — content or metadata — needs to reach us.
Who this matters most for: Defense subcontractors, clinics, and law firms in the 5–500 person range who need enforced AI controls and assessor-grade evidence now — without an enterprise platform project.
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.
