Privent hooks into CrewAI at the Agent and Task level as a middleware layer. It intercepts agent context, task memory, tool call arguments, and inter-task payloads, scoring risk before data crosses outside your infrastructure. Your crew runs uninterrupted.
Agent executes task
A CrewAI agent receives a task, queries tools, and generates responses. Data flows between agents (analyst passes output to executor, researcher feeds into writer), with no default visibility into what crosses each boundary.
Privent middleware intercepts
The middleware hook fires before each agent's external call. It reads agent context, task memory, tool call arguments, and inter-task payloads. ACARS scores the payload, accounting for what the entire crew has processed.
Data protected, crew continues
APE applies the appropriate transformation stage. The downstream agent or tool receives a safe, semantically coherent payload. Task completion is unaffected. Audit trail is recorded.
Add Privent to your existing CrewAI pipeline without changing your architecture. One addition. Full graph-state visibility.

External gateways receive only the final prompt string. Privent reads everything in context, in real time.
Prevents sensitive data discovered by one agent from propagating to the next agent in the crew chain, without breaking task continuity.
Detects when tool responses (database results, API responses) contain sensitive fields that would be passed into the next agent's context.
Flags proprietary business logic, M&A parameters, or pricing strategy embedded in analyst agent outputs before they reach external LLMs.
We integrate in under 30 minutes. No orchestration changes required. Your pipelines keep running. Privent keeps watching.
