# Secrets management

As the modern data orchestration service, Astro has been built and deployed with security as a guiding architectural principle. This same principle extends into how your sensitive information and credentials are stored and secured. Astro includes a [managed secrets backend](/docs/astro/manage-connections-variables#astro-environment-manager) for secure value encryption and storage, plus [integration with popular secrets management tools](/docs/astro/secrets-backend).

All secrets management configuration performed in the Astro UI is [securely transmitted and stored](/docs/astro/data-protection), is [resilient](/docs/astro/resilience) to in-region cloud failures, and can be [recovered](/docs/astro/disaster-recovery) in the case of a full control or data plane disaster.
