Ovlo — agentic threat model
Ovlo presents a high-risk profile due to its deep integration with critical enterprise ERP systems (SAP, NetSuite) and communication channels (Gmail, Slack), where compromised document processing (e.g., indirect prompt injection via malicious invoices) could lead to unauthorized financial transactions, though its human-in-the-loop exception routing provides a vital safety net.

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 specific foundation models used by Ovlo are not disclosed. Standard threats include adversarial prompt injection embedded in processed documents (invoices/POs) and model misalignment leading to incorrect data extraction.
Ovlo ingests highly sensitive business documents (invoices, purchase orders, certificates) and extracts structured data. The primary threat is data poisoning or indirect prompt injection via malicious incoming documents, which could manipulate the extraction logic or downstream ERP payloads.
The platform orchestrates multi-step workflows connecting document extraction to ERP systems and communication tools. Insecure tool integration is a major threat, where a hijacked workflow could execute unauthorized API calls to NetSuite, SAP, or Microsoft Dynamics.
Not certain from the listing — No details are provided regarding hosting environments, network isolation, secrets management for ERP credentials, or sandboxing of document processing engines.
Ovlo explicitly routes exceptions to humans instead of relying solely on automated entry. This human-in-the-loop (HITL) mechanism serves as a critical guardrail against drift, extraction errors, and adversarial inputs, though logging and evaluation metrics are not detailed.
Not certain from the listing — While the agent integrates with highly regulated enterprise systems (finance, supply chain), the listing does not specify compliance certifications (e.g., SOC 2, ISO 27001) or role-based access control (RBAC) policies.
Ovlo supports 'custom agents' that connect across various tools (Gmail, Slack, Google Sheets, ERPs). This introduces risks of cascading failures and trust abuse, where a compromise in a communication channel (e.g., Slack) could be leveraged to trigger unauthorized actions in the ERP agent.
MAESTRO — the 7-layer agentic threat-modeling framework (Cloud Security Alliance / Ken Huang).
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.
