TOOLS
Prompt Guardian is a lightweight, open-source toolkit that turns the taxonomy and defense guidance from Agentic AI Security: Threats, Defenses, Evaluation, and Open Challenges (Datta et al., 2025) into actionable prompt injection detections. Security practitioners can drop it into CI pipelines, red team harnesses, or agent gateways to obtain transparent risk signals that cite the exact whitepaper sections they originate from.
