Rebuff
Protect AI
Open source prompt injection detector that layers heuristics, a classifier prompt, a vector store of known attacks and canary tokens.
AI Security
Test and defend models, prompts, agents and the infrastructure around them.

How it differs Tests and guards models, LLM applications and agents against prompt injection, jailbreaks and data leakage. Scanning an AI app's own code is still SAST or SCA.

Alter
Commercial product in the AI security category addressing identity and access control for AI agents.
Lakera
Detection API that classifies prompts and model outputs for injection, jailbreak attempts, sensitive data and policy violations before they land.
Arize AI
LLM and ML observability platform that captures application traces and runs evaluations over them, with an open source tracing and evaluation component.
