| Rank | Model | Price | Summary |
|---|---|---|---|

Paid | The Zero-Day Defense. It uses a dynamic 'Immune System' database that updates hourly with new jailbreak vectors (e.g., 'Do Anything Now' variants). It is the industry standard for preventing prompt injection. | |
|
2
|
Open Source | The Open Standard. A Python framework that wraps LLM calls with 'Validators'. It ensures outputs strictly adhere to Pydantic schemas, effectively preventing the model from hallucinating invalid JSON or SQL. | |
|
3
|
Enterprise | The Model Scanner. Unlike others that scan prompts, HiddenLayer scans the *model weights* themselves. It detects if a downloaded model has been 'poisoned' or contains backdoors before you even load it into memory. | |
|
4
|
Paid | The Compliance OS. Essential for GDPR/HIPAA. It offers 'Data Residency as a Service', allowing you to redact PII and route data through specific geographic gateways to ensure compliance without building your own filters. |
