Cause (Documented platform behavior): With CRIS, the member account must be granted access to both the guardrail and the guardrail inference profile; automated reasoning policies are unsupported for enforcement and cause runtime failures.
Fix status: documented_behavior
Limitations:
- Source is an AWS-authored sample notebook (aws-samples), not the Bedrock User Guide.
- RBP attachment was console-only at the notebook's time.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/aws-samples/amazon-bedrock-samples/b5ad367ad897dc8dbb9af0f671b58129d4e19672/responsible_ai/bedrock-guardrails/bedrock_guardrails_enforcements_tutorial.ipynb (official_docs, unknown, documented_behavior): AWS sample: with Cross-Region Inference you must attach RBPs to BOTH the guardrail and the guardrail inference profile, otherwise member accounts receive 'AccessDeniedException: The provided resource ARN is from a different account'; do not include automated reasoning policy (unsupported, runtime failures); enforcement must be configured in every region.
Search phrasings: bedrock guardrail enforcement organizations access denied different account; bedrock guardrail profile resource based policy cross region

Problem details
- Observed symptom
- After enabling org-level guardrail enforcement, member-account model calls fail with AccessDenied.
- Context
- Product: Amazon Bedrock Guardrails Component: Organization/account-level enforced guardrails with crossRegionConfig Operation: Member-account InvokeModel/Converse under an org-enforced guardrail Affected versions: unknown Environment: AWS Organizations with Bedrock policy type; guardrail using a system-defined guardrail profile (e.g. us.guardrail.v1:0) HTTP status: 403 Exception: AccessDeniedException Trigger: Attaching a resource-based policy (RBP) to the guardrail but not to its cross-Region guardrail profile; or including an automated reasoning policy in an enforced guardrail.

Proposed fix: [Bedrock Guardrails enforcement across AWS Organizations] AccessDeniedException 'The provided resource ARN is from a different account' — cross-Region guardrail profile also needs a reso
Recommended action: Attach RBPs to both the guardrail and the guardrail profile (console), create an immutable guardrail version, verify ApplyGuardrail from a member account before enforcing, and configure enforcement per region.
Option: Attach RBPs to guardrail and guardrail profile [evidence: official_recommended_action]
Steps:
1. Create guardrail version.
2. Attach RBP to guardrail and to the system-defined guardrail profile.
3. Test ApplyGuardrail from a member account.
4. Then enable org/account enforcement.
Expected: Member calls succeed with guardrail applied.
