6060* Message content, files and attachments (both inline attachments sent with a request and Files API uploads), and MCP and tool configuration.
61* [Claude Managed Agents](https://platform.claude.com/docs/en/managed-agents/overview) data, including agent configurations, environments, webhooks, sessions and their events, [memory stores](https://platform.claude.com/docs/en/managed-agents/memory) and their memories and memory versions, and [dreams](https://platform.claude.com/docs/en/managed-agents/dreams).
61* [Claude Managed Agents](https://platform.claude.com/docs/en/managed-agents/overview) (beta) data, including agent configurations, environments, webhooks, sessions and their events, [memory stores](https://platform.claude.com/docs/en/managed-agents/memory) (beta) and their memories and memory versions, and [dreams](https://platform.claude.com/docs/en/managed-agents/dreams) (research preview).
62* Data stored at rest by the Batch and Skills APIs, and by these tools: web search, web fetch, code execution, bash, text editor, MCP connector (beta), structured outputs, advisor tool (beta), computer use, browser use, and context management.

from line 70
6970* Compliance API [local session transcripts](https://platform.claude.com/docs/en/manage-claude/compliance-sessions#retrieve-local-sessions) captured from sessions on users' machines. If your key cannot 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.
7071* Office agents.
7172* Claude in Chrome.
72* Claude Science. Data that users send from the app to their own compute, such as SSH hosts or cloud compute accounts, is held on those systems, not by Anthropic, and is not covered.
73* Claude Science, which is in beta.
7374
7475On both products, backups and snapshots inherit the key.

8283* Playground in the Claude Console is disabled.
8384* Portions of the Compliance API that return raw content, such as prompts, responses, and files, are disabled.
85* Structured outputs are not available for Claude Fable or Claude Mythos models in CMEK organizations.
8486* Other beta and research preview features might not be covered by CMEK.

from line 89

8890* Chat search is disabled because chat titles and content are encrypted under your key. Members cannot search past chats, and the **Search and reference chats** toggle stays off, so Claude cannot search them either.
8991* [Project knowledge search](https://support.claude.com/en/articles/11473015-retrieval-augmented-generation-rag-for-projects) (retrieval-augmented generation, or RAG) is disabled. Project knowledge loads directly into each conversation's context instead of being indexed and searched. As a result, a project can use substantially less knowledge than it could without CMEK. Knowledge beyond what can be loaded is left out of the conversation.
90* Claude Code on the web (including routines) and Claude in Slack are unavailable: new sessions cannot be started and Claude in Slack declines requests, even if an admin turns these products on. Claude Code Desktop remains available for local sessions but is off unless an admin turns it on under [claude.ai > Organization settings > Claude Code](https://claude.ai/admin-settings/claude-code).
91* In conversations and the **Artifacts** tab, Claude Design, Claude Slides, and Claude Docs are unavailable, and admins cannot turn them on. Claude Code cannot [publish artifacts](https://code.claude.com/docs/en/artifacts#availability).
92* Claude Code on the web and Claude in Slack are unavailable: new sessions cannot be started and Claude in Slack declines requests, even if an admin turns these products on. Claude Code Desktop remains available for local sessions but is off unless an admin turns it on under [claude.ai > Organization settings > Claude Code](https://claude.ai/admin-settings/claude-code).
93* Artifacts cannot be shared publicly, only within your organization.
9294* Certain analytics are degraded: admin analytics for claude.ai skills and connectors (under claude.ai/analytics/usage and through the [Claude Enterprise Analytics API](https://platform.claude.com/docs/en/manage-claude/analytics-api)), Claude smart reports (under claude.ai/analytics/insights), and Claude Code contribution metrics (under claude.ai/analytics/claude-code).
9395* Organization data exports and audit log exports, both under [claude.ai > Organization settings > Data and privacy](https://claude.ai/admin-settings/data-privacy-controls), are disabled.
9496* Response ratings (thumbs up and thumbs down on Claude's responses) are disabled.
97* The following beta and research preview features are unavailable in CMEK organizations, regardless of admin settings: Claude Design, Claude Slides, and Claude Docs in conversations and the **Artifacts** tab, and routines.

110113* [Personal preferences - Instructions for Claude section](https://claude.ai/new#settings/account) and Cowork Global instructions. These are set at the account level and shared across all of a user's organizations.
111114
112115On both products, account data for users in your organization (such as names, email addresses, and profile pictures) is not encrypted under your key.
