Safeguard tiers for guardrails policies

Amazon Bedrock Guardrails provides safeguard tiers for specific policies. Safeguard tiers have distinct performance characteristics and language support for different application requirements and use cases.

Choosing a tier gives you control over when to adopt new capabilities or maintain consistency with your current guardrails setup.

The following guardrails policies support safeguard tiers:

Available safeguard tiers

Amazon Bedrock Guardrails provides the following safeguard tiers:

Standard tier

Provides more robust performance compared to Classic tier and has more comprehensive language support. For example, protection against prompt attacks performs more consistently and reliably with Standard tier. Guardrails with Standard tier also use cross-Region inference.

Classic tier

Provides established guardrails functionality supporting English, French, and Spanish languages.

Key differences between safeguard tiers

Understanding the differences between safeguard tiers helps you choose the right option for your application:

Feature Standard tier Classic tier
Content filter and prompt attacks More robust than Classic tier Established performance
Denied topics Maximum of 1,000 characters per definition Maximum of 200 characters per definition
Language support Extensive language support English, French, Spanish
Cross-Region inference Supported Not supported

Choosing a safeguard tier for your use case

Determining the safeguard tier to use for your guardrail policies depends on your application requirements.

For example, consider Standard tier when:

  • Your application handles multiple languages

  • You need higher accuracy and performance for content filters, prompt attacks, and denied topics

Alternatively, you might still use Classic tier when:

  • Your application primarily uses English, French, or Spanish content

  • You need time before migrating from an existing guardrails implementation to Standard tier

Migrating your guardrail to Standard tier

To configure an existing guardrail with Standard tier, do the following:

  1. Modify your guardrail to use Standard tier and cross-Region inference.

  2. (Recommended) Consider rolling out your updated guardrail using a phased approach by starting with noncritical workloads.
