AI SDR — agentic threat model
The AI SDR agent presents moderate-to-high risk due to its direct, autonomous interaction with external prospects via voice and its write-access integration with CRMs and scheduling systems. A compromise or prompt injection could lead to reputational damage, CRM data corruption, or unauthorized calendar manipulation.

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 LLM and voice synthesis models are undisclosed. Threats include voice-based prompt injection (jailbreaking via phone), adversarial inputs causing the agent to agree to unauthorized terms, or model hallucination during sales pitches.
Not certain from the listing — The agent utilizes custom rules, sales scripts, and CRM data. Threats include knowledge-base poisoning (injecting malicious scripts) and unauthorized exfiltration of customer contact details during the RAG/retrieval phase.
The agent orchestrates call flows, qualifies leads based on rules, and executes tool calls to log summaries in CRMs and book meetings. Threats include insecure tool integration where an attacker manipulates the conversation to force unauthorized CRM writes or calendar spamming.
Not certain from the listing — Hosted as a closed-source SaaS by JustCall. Threats include SIP/voice stream interception, exposure of CRM API keys, and lack of network isolation between tenant databases.
Not certain from the listing — The system logs call summaries to the CRM, but the presence of real-time guardrails, prompt injection detection, or voice anomaly monitoring is not detailed.
Not certain from the listing — No specific compliance certifications (e.g., SOC2, ISO 27001) or fine-grained access controls for the CRM integrations are detailed in the public directory listing.
Not certain from the listing — While primarily a single-agent solution interacting with APIs, threats include cascading failures if CRM-triggered downstream automation agents trust the AI SDR's summarized outputs blindly.
