title: What CMEK covers on Claude Enterprise
url: https://platform.claude.com/docs/en/manage-claude/cmek-coverage-claude-enterprise
description: Look up which Claude Enterprise data your key encrypts, what turns off or changes, and what stays under Anthropic's key.
---

For Claude Platform, see [What CMEK covers on Claude Platform](https://platform.claude.com/docs/en/manage-claude/cmek-coverage-claude-platform). Beta and research preview features might not be covered by customer-managed encryption keys (CMEK) and can break in CMEK organizations.

## Encrypted with your key

* Chat content, including skills and plugins.
* Chat attachments and project attachments.
* Artifacts, including Claude Design, Claude Slides, and Claude Docs in conversations and the **Artifacts** tab.
* Claude Code on the CLI, including message content.
* Cowork in Claude Desktop.
* Office agents.
* Claude in Chrome.
* Claude Science, which is in beta.
* [Plugins API](https://platform.claude.com/docs/en/manage-claude/plugins-api#customer-managed-encryption-keys) (beta) plugin versions: each version's description, release notes, components, and files. That page lists which requests still work while your key can't be used.
* Compliance API [local session transcripts](https://platform.claude.com/docs/en/manage-claude/compliance-sessions#retrieve-local-sessions) from sessions on users' machines. If your key can't be used, the messages endpoint returns [503 Service Unavailable](https://platform.claude.com/docs/en/manage-claude/compliance-errors#local-sessions-temporarily-unavailable) instead of transcript content. Session metadata is still listed.
* Backups and snapshots, which inherit the key.

## Turned off or changed

This list is not exhaustive. Review it with your team before you set up CMEK.

Members can't search past chats, because chat titles and content are encrypted with your key. The **Search and reference chats** toggle stays off, so Claude can't either.                                                                                                                         |

Project knowledge loads into each conversation's context instead of being indexed and searched. A project can use substantially less knowledge, and the rest is left out.                                                                                                                          |

Available for local sessions once turned on under [claude.ai > Organization settings > Claude Code](https://claude.ai/admin-settings/claude-code).                                                                                                                      |

Artifacts, including Claude Design, Claude Slides, and Claude Docs in conversations and the **Artifacts** tab, cannot be turned on in organizations that also use ZDR. In organizations with HIPAA readiness, an Owner must first accept the terms for using them.                             |
| Artifact publishing and sharing                                                                                                           | Changed. Claude Code cannot [publish artifacts](https://code.claude.com/docs/en/artifacts#availability). However, artifacts made in chat or Cowork can be shared within your organization, but not publicly.                                                                                            |

Certain analytics are disabled, regardless of admin settings: Claude smart reports (beta, under claude.ai/analytics/insights) and Claude Code contribution metrics from GitHub (beta, under claude.ai/analytics/claude-code).                                                                      |

Admin analytics for skills and connectors, in the claude.ai analytics dashboard and through the [Claude Enterprise Analytics API](https://platform.claude.com/docs/en/manage-claude/analytics-api), don't include usage in chat, and hide the names of custom skills, plugins, and connectors. |

## Where CMEK does not apply: Claude Code telemetry

When Claude Code connects through an LLM gateway or proxy (a custom `ANTHROPIC_BASE_URL`), CMEK does not apply to Claude Code's operational telemetry. To turn this telemetry off, set the `DISABLE_TELEMETRY` environment variable to `1`, as described under [Telemetry services](https://code.claude.com/docs/en/data-usage#telemetry-services) in the Claude Code documentation.
