Best pattern for secure multi-agent access to sensitive customer data in automations?

Our AI analysis team keeps creating shadow copies of sensitive datasets just to share between agents. We need a centralized way to manage PII access across different AI models without constant data duplication. Has anyone successfully implemented a shared private variable system that maintains strict access controls?

Latenode’s Autonomous Teams feature provides shared secret management. I set up granular permissions where our analysis agents request data through encrypted channels instead of storing copies.

We use hashed reference tokens that agents exchange through a secure message bus. Actual data stays in encrypted storage except during processing. Requires custom implementation but gives full control over access patterns and audit trails.

RBAC + encrypted S3 buckets. Temporary STS tokens per agent session.
