Gemma 4 — agentic threat model
Gemma4.app is a low-risk informational and model-access portal with an online demo, presenting minimal direct agentic risk due to its lack of autonomous action, tool use, or planning capabilities. The primary security concerns lie in traditional web application security and potential supply chain risks if download links to the open-source model weights were compromised.
OWASP AIVSS score rationale

| Persistent Memory | 0.10 | |
| Contextual Awareness | 0.20 | |
| Dynamic Identity | 0.00 | |
| Multi-Agent Interactions | 0.00 | |
| Non-Determinism | 0.50 | |
| Opacity & Reflexivity | 0.40 |
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.
The platform's core focus is Gemma 4, an open-source foundation model. Key threats include prompt injection, jailbreaking of the online demo, and potential model poisoning or supply chain tampering of the downloadable weights.
Not certain from the listing — The platform provides a demo and download links, but details about RAG, vector stores, or training data operations for the hosted demo are not specified.
Not certain from the listing — The platform is a portal for model access and setup guides rather than an active agentic orchestration framework, so tool integration or agent memory threats are not applicable here.
Not certain from the listing — While it mentions local and mobile setup guides, the hosting infrastructure of the online demo itself is not detailed, posing standard web hosting and container security risks.
Not certain from the listing — There is no mention of built-in guardrails, monitoring, or evaluation frameworks for the online demo or the distributed models.
Not certain from the listing — No specific compliance certifications (e.g., ISO, NIST) or identity/authorization controls are detailed for the platform or its demo.
Not certain from the listing — The platform operates as a single-model hub and does not feature multi-agent interactions or marketplace integrations.

These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification.
