Rivio — agentic threat model
Rivio presents a high-risk profile due to its multi-agent architecture handling highly sensitive legal and financial software contracts, with the ability to initiate and manage renewal workflows. A compromise could lead to massive data exfiltration of proprietary pricing or unauthorized financial commitments through manipulated approval workflows.

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 — likely relies on commercial LLMs (e.g., GPT-4) for contract extraction and conversational retrieval. Threats include prompt injection leading to unauthorized contract data disclosure or manipulation of renewal logic.
Ingests and analyzes software contracts to build a 'Procurement Brain' knowledge base. Threats include contract data poisoning (malicious clauses injected into uploaded PDFs) and unauthorized data exfiltration of sensitive pricing/terms.
Orchestrates multi-agent workflows for vendor and contract management, including planning renewals. Threats include insecure tool integration (e.g., workflow engines, email APIs) and state manipulation across the multi-step renewal process.
Not certain from the listing — likely hosted as a SaaS platform with API integrations. Threats include container compromise, insecure storage of ingested contract PDFs, and exposure of API keys used to connect to procurement systems.
Not certain from the listing — no mention of continuous evaluation or guardrails. Threats include blind spots in multi-agent communication and lack of audit logs for automated contract extraction decisions.
Not certain from the listing — handles highly sensitive legal and financial data but does not specify compliance certifications (e.g., SOC 2, GDPR). Threats include unauthorized access to confidential contract terms and lack of strict role-based access control (RBAC).
Multi-agent system with specialized agents for vendor and contract management. Threats include cascading failures if one agent (e.g., contract extraction) passes corrupted or malicious data to another (e.g., renewal workflow manager), and trust abuse between agents.
