OpenAI Moderation API vs Prisma AIRS AI Runtime Security API

OpenAI Moderation API

Free, on any OpenAI project key. No prompt-injection, jailbreak or PII detection.

Prisma AIRS AI Runtime Security API

A public OpenAPI document, ten detection types in one call, tool-call scanning, a remote MCP server, rotating API keys and OAuth roles suit teams already on Strata Cloud Manager. Access needs Software NGFW credits bought through sales, with no public price, trial or self-serve signup, and payloads flagged malicious are kept for up to 10 years.

OpenAI Moderation API

1. Read category_scores rather than flagged alone. The default thresholds are OpenAI's
2. Pin omni-moderation-2024-09-26 if the scores feed a decision you audit. The latest alias will move
3. Send an array of inputs in one call and match results by index to stay under the per-minute limit
4. Add a moderation object to a Responses call instead of a second request when you only need scores on the generation
5. Pair it with a separate injection detector. A clean result says nothing about a hidden instruction in a tool result

Prisma AIRS AI Runtime Security API

1. Send x-pan-token and an ai_profile with profile_name or profile_id on every scan. Both come from Strata Cloud Manager, and a key works only in its own region
2. Put earlier turns first in contents. Only the last element is scanned, and the rest is context
3. Read action (allow or block) and category, then check timeout and error, because a detector that failed is reported in errors with a 200
4. Keep synchronous requests under 2 MB and asynchronous ones under 5 MB and 25 items, and fetch at most 5 scan or report IDs a call, 10 calls a minute
5. For MCP, connect to /mcp on the regional host with x-pan-token and x-pan-profile headers, and call pan_inline_scan yourself before and after generation
