Exei — agentic threat model
Exei presents a high agentic risk profile due to its deep integration with external communication channels (WhatsApp, Slack, VOIP) and its ability to execute real-time actions like ticketing and scheduling. The primary threat vector is prompt injection via public-facing channels leading to unauthorized API execution or data exfiltration.

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 — Exei is closed-source and likely relies on third-party commercial LLMs. The primary L1 threats are adversarial prompt injection via public customer-facing channels (WhatsApp, Facebook, VOIP) which could bypass system instructions to manipulate the agent's behavior.
Exei trains on diverse sources including website data, documents, manuals, and real-time API data. This creates a significant risk of RAG/knowledge-base poisoning if an attacker can manipulate the public website or documents, leading to unauthorized data exfiltration or biased agent responses.
The agent framework orchestrates automated appointment scheduling, ticket/task creation, and real-time AI actions via APIs. Insecure tool integration is a major threat here, where malicious user inputs could trick the agent into executing unauthorized API calls or creating fraudulent tickets.
Not certain from the listing — The hosting environment, API gateway security, and sandboxing mechanisms are not detailed. Compromise at this layer could expose API keys for integrated channels (Slack, WhatsApp, VOIP) or allow lateral movement into connected business systems.
Not certain from the listing — While Exei provides 'Actionable Analytics' on customer behavior and sentiment, it is unclear if it has dedicated security observability, real-time guardrails, or anomaly detection to identify and block adversarial prompt injections.
Not certain from the listing — The platform features 'Human Escalation' as a fallback control, but the listing does not specify compliance alignments (such as SOC2 or GDPR) or robust role-based access controls (RBAC) for managing the training data and API integrations.
Not certain from the listing — There is no explicit mention of multi-agent orchestration or marketplace interactions. However, because it integrates horizontally across multiple communication ecosystems (Slack, VOIP, social media), a compromise in one channel could cascade to others.
