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.
45 tools profiled
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.

Open source prompt injection detector that layers heuristics, a classifier prompt, a vector store of known attacks and canary tokens.
Runlayer
Commercial control layer for AI agent tool access, mediating connections between agents and the systems they act on.
Straiker
Commercial AI security platform pairing automated adversarial testing of AI applications with runtime inspection of prompts and responses.
Vectara
Managed retrieval augmented generation platform whose security relevance is grounding, citation and a hallucination evaluation model applied to responses.

WhyLabs
Observability platform for ML and LLM systems built on lightweight statistical profiles, with drift monitoring and text quality and safety metrics.
WitnessAI
Governance platform that observes AI traffic across an organization, discovers unsanctioned tool use, and applies policy to prompts and responses.
Xage Security
Distributed zero trust access platform for operational and industrial environments, extended to control what machine and AI agent identities may do.
