AWS bedrock documentation change

Service: bedrock · 2026-04-19 · Documentation low

File: bedrock/latest/userguide/guardrails-cross-region-support.md

Summary

Expanded cross-region support for guardrails by adding eu-south-1 to European regions and adding new geographic boundaries (UK, Australia, Canada) with their respective guardrail profiles and supported regions.

Security assessment

This change documents expanded regional availability of guardrail profiles, which are security features that help filter harmful content and manage model behavior. The update adds new geographic boundaries (UK, Australia, Canada) and expands European region support, but does not indicate any security vulnerability fix or incident response. It enhances security documentation by providing more comprehensive coverage of available security controls across regions.
