The record

Purpose: Inferwall describes itself as an AI firewall that scans LLM app inputs and outputs against signatures for threats including prompt injection, jailbreaks, data leakage, and unsafe content.
Detection layers: It combines heuristic, machine learning, semantic, and configurable LLM judge detection layers.
Deployment: Inferwall can be deployed as a Python SDK, standalone HTTP server, or transparent reverse proxy.
Integrations: The site lists first party wrappers for OpenAI, Anthropic, LangChain, and FastAPI.
Additional ecosystem support: The site lists Ollama, Hugging Face, LlamaIndex, Pydantic, vLLM, and Mistral among supported stack integrations.
Performance: The site says its Rust heuristic engine runs in under 0.3 ms at p99 and requires no GPU in the Lite profile.
Install profiles: The site describes Lite as about 8 MB, Standard as including about 730 MB of models, and Full as including those models plus LLM credentials.
Policy controls: Users can set allow, flag, or block thresholds per route and extend or override signatures under ~/.inferwall/.
Security mapping: The site says its prompt injection, jailbreak, prompt extraction, and data leakage signatures map to MITRE ATLAS techniques AML.T0051, AML.T0054, AML.T0056, and AML.T0057.
Licensing: The engine is licensed under Apache 2.0 and community signatures under CC BY-SA 4.0.
Limitations: The site states that no detection system is perfect and presents Inferwall as one layer of a defense in depth strategy.
