Protect AI
Protect AI is an AI/ML security platform (now part of Palo Alto Networks) whose products secure the AI lifecycle from model selection to runtime. Its developer surface centers on LLM Guard, an open-source Python toolkit of prompt and output scanners that ships a self-hostable REST API for real-time input/output sanitization. Commercial products - Guardian (model scanning), Recon (LLM red-teaming), and Layer (runtime protection) - are delivered through a portal under sales-led terms.
Protect AI publishes 6 API contracts indexed on the APIs.io network, including Output API, Prompt API, System API, and 3 more. Tagged areas include Artificial Intelligence, Machine Learning, Security, LLM, and Guardrails.
The Protect AI catalog on APIs.io includes 1 Spectral governance ruleset.
Protect AI’s developer surface includes authentication, documentation, engineering blog, and 9 more developer resources.
Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Cloud Security Attestation and Secure-by-Design | standard | 44.1 | - | - |
| Hugging Face Hub Organisations | standard | 44.1 | - | - |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 1
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
