Needs an Azure subscription with a card, a resource and a region that has the feature, before the first call.\n\n**LlamaFirewall.** One `scan()` call runs several checks on the owner's machine and returns a short typed result. The last PyPI release is 1.0.3 from 29 May 2025, and its Prompt Guard loader imports a `huggingface_hub` class that current versions no longer export, so a fresh install needs older pins. The classifier weights also need Meta's manual approval.\n\n## Before you call either\n\n### Azure AI Content Safety (Prompt Shields)\n\n1. Send retrieved pages and tool results in the documents array of shieldPrompt, not in userPrompt, so document attacks are reported separately\n2. Call text:shieldPrompt over REST with api-version=2024-09-01. The Python SDK 1.0.0 has no method for it\n3. Keep each request under 10,000 characters across prompt and documents, and split long tool results\n4. Create the resource in a region that lists Prompt Shields, since not every region has it\n5. On F0 you get 5 requests a second. Queue checks or move to S0 before load testing\n\n### LlamaFirewall\n\n1. Pin `huggingface_hub` below 1.0 and a matching `transformers` 4.x before importing the Prompt Guard scanner from the 1.0.3 wheel, or install from main\n2. Get access to `meta-llama/Llama-Prompt-Guard-2-86M` and set a Hugging Face token first. Without one the loader prompts for a login and a headless run stalls\n3. Call `scan_async` inside a running event loop. `scan()` wraps `asyncio.run` and fails there. `scan_async` returns score 0.0 and reason `default` on every allow\n4. Split text longer than 512 tokens yourself before a Prompt Guard scan. The library truncates and does not chunk\n5. Do not feed a block `reason` back to the model. The Prompt Guard reason quotes the full scanned text, and the hidden ASCII reason decodes the hidden payload\n\n## Questions\n\n### Which is better for AI agents, Azure AI Content Safety (Prompt Shields) or LlamaFirewall?\n\nAzure AI Content Safety (Prompt Shields) scores 60.7 (C) on agent readiness against LlamaFirewall's 50.8 (D), and leads in 6 of 7 scored categories. LlamaFirewall leads on payments \u0026 pricing.\n\n### Can an agent call Azure AI Content Safety (Prompt Shields) and LlamaFirewall without installing anything?\n\nAzure AI Content Safety (Prompt Shields) has a hosted endpoint at https://{resource}.cognitiveservices.azure.com/contentsafety/text:shieldPrompt. No hosted endpoint is listed for LlamaFirewall.\n\n### Are Azure AI Content Safety (Prompt Shields) and LlamaFirewall open source?\n\nNo open-source release is listed for Azure AI Content Safety (Prompt Shields). LlamaFirewall is open source (MIT (library). The Prompt Guard 2 weights it downloads are under the Llama 4 Community Licence).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/azure-ai-content-safety-vs-llamafirewall.json, and with the fewest tokens: https://www.anchorterminal.com/compare/azure-ai-content-safety-vs-llamafirewall.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"azure-ai-content-safety\", \"b\": \"llamafirewall\"}`.
