SayBriefly — agentic threat model

Not certain from the listing — likely relies on third-party foundation models for transcription and summarization. The primary threat is indirect prompt injection, where malicious instructions spoken during a meeting or embedded in shared materials could manipulate the model's summary or trigger unauthorized actions.

Not certain from the listing — processes and stores highly sensitive meeting audio, transcripts, and project briefs. Threats include data exfiltration of confidential client calls, lack of robust encryption at rest/in transit, and potential data leakage across multi-tenant workspaces.

Not certain from the listing — orchestrates transcription, summarization, and scheduling workflows. Threats include insecure tool integration with calendar APIs, allowing malicious inputs to manipulate scheduling or workspace configurations without explicit user consent.

Not certain from the listing — hosted as a closed-source SaaS platform. Threats include insecure cloud infrastructure hosting the transcription engines, exposed API endpoints, and inadequate sandboxing of document processing environments.

Not certain from the listing — no mention of LLM guardrails or observability tools. Threats include a lack of monitoring for prompt injection attempts in meeting transcripts and insufficient logging of automated scheduling actions.

Not certain from the listing — freemium SaaS model with no cited compliance certifications (e.g., SOC2, GDPR). Threats include weak multi-tenant isolation, lack of granular access controls for shared team workspaces, and potential legal/compliance issues regarding meeting recording consent.

Not certain from the listing — primarily functions as a standalone assistant with external integrations (calendars, workspaces). Threats include API trust abuse where compromised external calendar services could inject malicious payloads into the agent's workspace.
