**For administrators:**
  These guides cover configured enterprise environments. For the developer
  trial, start with [Your first governed agent](https://docs.atensecurity.com/docs/getting-started/quickstart).
  Confirm enabled integrations and release artifacts before using a fleet runbook.

Start with validation when setting up an environment. Use the focused runbooks
below for routine maintenance or when something goes wrong.

## Choose a runbook

- [Validate the control plane](https://docs.atensecurity.com/docs/operations/headless-e2e-runbook): Check API, CLI, proxy, webhook, and approval flows end to end.
- [Rotate API keys](https://docs.atensecurity.com/docs/operations/key-rotation): Update credentials used by your integrations.
- [Respond to an incident](https://docs.atensecurity.com/docs/operations/incidents): Investigate issues and follow the incident response runbook.
- [Roll back a deployment](https://docs.atensecurity.com/docs/operations/rollback): Follow the rollback procedure when a rollout needs to be reversed.

## Before an upgrade

Review the [changelog](https://docs.atensecurity.com/docs/changelog) and
[release-channel guidance](https://docs.atensecurity.com/docs/deployments/release-channels). Use the
[validation matrix](https://docs.atensecurity.com/docs/deployments/validation-matrix) to plan checks for your environment.
