Voxmo — agentic threat model
Voxmo presents a moderate-to-high risk profile due to its autonomous voice interaction capabilities and direct integration with sensitive business systems like CRMs and calendars. A compromise could lead to automated social engineering (vishing) attacks and unauthorized data exfiltration from connected customer databases.

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 specific foundation models for speech-to-text, text-to-speech, and LLM orchestration are not disclosed. Threats include voice-based prompt injection, adversarial audio inputs, and model reprogramming to output inappropriate content during live calls.
The agent is trained on your services/products and syncs with CRM data. Threats include knowledge-base poisoning (injecting false product details) and data exfiltration of sensitive customer CRM records via prompt extraction during voice conversations.
The agent orchestrates tools for calendar booking and CRM synchronization. Threats include insecure tool integration, where a malicious caller could manipulate the agent into executing unauthorized API calls to delete calendar events or corrupt CRM data.
Not certain from the listing — The hosting environment, telephony infrastructure (SIP/VoIP), and secrets management for CRM/calendar API keys are undisclosed. Threats include API key theft and unauthorized access to the telephony gateway.
Not certain from the listing — While Voxmo generates full call logs and recaps, it is unclear if there are real-time guardrails, automated drift detection, or security monitoring to detect adversarial manipulation during live calls.
Not certain from the listing — No compliance certifications (e.g., SOC2, ISO 27001, HIPAA) or specific identity/authorization controls for accessing the call logs and CRM integrations are mentioned.
Not certain from the listing — There is no indication of multi-agent collaboration or marketplace interactions. The primary ecosystem threat is limited to cascading failures in connected third-party CRM and calendar platforms.
