Zero-trust networking for agentic AI with Amazon VPC Lattice

This article demonstrates how to use Amazon VPC Lattice to securely connect AI agents to sensitive data in isolated VPCs using zero-trust networking principles.

• VPC Lattice provides IAM-based authentication and authorization for every request, regardless of network location
• Enforce HTTP method restrictions at the network layer (e.g., read-only agents limited to GET requests)
• Automatic TLS encryption and certificate management between services across VPCs and accounts
• Cross-account service sharing via AWS Resource Access Manager without VPC peering or complex routing
• Comprehensive access logging to CloudWatch Logs or S3 for HIPAA audit trail requirements
• Implementation uses Strands Agents with Amazon Bedrock to query FHIR API in private VPC with SigV4 signing
• Preserves network isolation—data VPC requires no internet-facing routes or modifications

VPC Lattice enables secure AI agent connectivity to sensitive data while maintaining strict network isolation and compliance requirements for regulated industries like healthcare and finance.
