Single-Judge Scanner is a scanner that scores LLM responses with one model judge. AI-SPM is the broader programme that adds asset discovery, adversarial testing, runtime gateway controls, and control-ID compliance evidence.

Problem
What AI-SPM vs Single-Judge Scanner really means
Single-Judge Scanner covers a slice of AI risk. The gap is the rest of the AI control surface: a single model grading another single model inherits the same blind spots; no consensus mechanism, no human review queue for low-confidence cases.
How Penaxtra approaches it
How Penaxtra closes the gap
AI-SPM is purpose-built for the full AI control surface: 11 AI asset kinds today, three-judge adversarial testing, self-hosted runtime gateway, and six-framework compliance evidence. Most customers run AI-SPM alongside Single-Judge Scanner rather than replacing it.
