AI Security Guard — agentic threat model
AI Security Guard acts as a defensive security agent and SDK with low inherent autonomy, designed to monitor and protect other agents. Its primary risk lies not in its own agentic actions, but in the potential for bypass or false negatives in its jailbreak and injection detection capabilities.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — The listing mentions supporting 500+ LLM models for cost tracking and using machine-learning-aided scanning, but does not specify which foundation models AI Security Guard itself uses to perform its analysis.
The agent uses a privacy-first architecture that keeps data on the user's device by default, significantly reducing the risk of data exfiltration and centralized knowledge-base poisoning.
Not certain from the listing — While the SDK wraps the API into simple function calls to prevent tool misuse in client agents, the internal orchestration framework of the guard itself is not described.
Features a 'Shield scanner' that performs 14-phase device hardening scans to protect the agent's environment, directly addressing host compromise and infrastructure vulnerabilities.
This is a core strength; the agent provides 'Radar' runtime scanning of ingested/produced content, health grades, security posture tracking, and budget/token spend intelligence to eliminate observability blind spots.
Directly addresses security and compliance by preventing credential leaks (API keys, secrets), detecting jailbreaks, and screening for harmful content via its underlying API.
Designed to secure the broader agent ecosystem by scanning the content that other agents produce and ingest, mitigating cascading failures and trust abuse between interacting agents.
