What problem does it solve?

Harden AgentCore deployments for production by enforcing secure IAM scoping, robust inbound authentication, secrets protection, and optimized session lifecycle to prevent outages and security gaps.

Core Features & Use Cases

IAM scope hardening and least-privilege policies for agent runtimes
Inbound authentication safeguards (AWS_IAM or CUSTOM_JWT) and issuer discovery validation
Secrets management and credential hygiene to avoid hard-coded keys
Cold-start and session lifecycle tuning plus production-ready guardrails
Production readiness checklists and quota guidance to prevent outages
Observability and auditing hooks to monitor security and reliability

Quick Start

Run the production readiness checklist for your AgentCore runtime to verify inbound auth, IAM scope, and session lifecycle.

FAQPage Schema

How do I harden AgentCore agents for production?▼

To harden AgentCore agents for production, you enforce secure IAM scoping, configure robust inbound authentication, protect secrets, and tune the session lifecycle. This process validates your CLI version and applies guardrails to prevent live environment outages.

What is included in production readiness checks for agent runtimes?▼

Production readiness checks for agent runtimes include verifying inbound authentication, IAM scope, cold-start optimization, and quota guidance. These checks ensure your deployment meets reliability and security standards before handling live traffic.

How do I configure inbound authentication for AgentCore deployments?▼

Configuring inbound authentication for AgentCore deployments involves implementing AWS_IAM or CUSTOM_JWT safeguards with issuer discovery validation. This prevents unauthorized access to your live agent endpoints.

Do I need to manage IAM scopes separately when securing agent runtimes?▼

Managing IAM scopes is integrated directly into securing agent runtimes by applying least-privilege policies automatically. This ensures the runtime only accesses necessary resources without manual policy writing.

How do I prevent outages from cold-starts in production agent sessions?▼

To prevent outages from cold-starts in production agent sessions, you tune the session lifecycle and apply rate limiting alongside quota guidance. These guardrails maintain performance during traffic spikes.
