Polymer is a well-priced, transparent SaaS DLP with good SMB UX. But it's cloud-routed general DLP — it isn't built to keep CUI on-prem, and it doesn't produce a CMMC-mapped assessment artifact.
| Dimension | HoundShield | Polymer |
|---|---|---|
| Where data is scanned | Locally (Mode B/C) | Polymer's cloud |
| Pricing transparency | $499 report + published plans | Transparent, low per-user |
| CMMC / NIST 800-171 evidence PDF | Yes | No |
| Air-gapped deployment | Yes (Mode C) | No |
| General SaaS DLP breadth | AI-prompt focused | Broad SaaS DLP |
| Regulated-industry fit | CMMC/HIPAA-first | General-purpose |

Polymer provides low-cost, transparently priced SaaS DLP with a self-serve model, focused on scanning data in cloud SaaS apps and some AI surfaces. Inspection runs in Polymer's cloud.
HoundShield Mode B keeps prompt content on-prem. Polymer inspects in its cloud — fine for general data, not for CUI/PHI that can't leave the boundary.
HoundShield ships a $499 NIST 800-171-mapped report. Polymer is DLP tooling, not a compliance-evidence deliverable.
Mode C runs offline for IL-5+ networks — beyond a cloud SaaS DLP's reach.
16 detection engines tuned for CUI/PHI/ITAR/CAGE/clearance markers in prompts, plus a SHA-256 hash-chained audit trail.
Who this matters most for: Healthcare (Rachel) and legal (Marcus) teams that liked Polymer's price but need regulated-data guarantees and an evidence artifact.
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.
