366366* **Isolated virtual machines**: each session runs in an isolated, Anthropic-managed VM. Sessions your organization routes to a [self-hosted environment](/docs/en/self-hosted-environments) run on your own infrastructure instead, where isolation is your deployment's responsibility
367367* <span id="default-allowed-domains" />**Network access controls**: in Anthropic-hosted environments, network access is limited by default and can be disabled. See [Network access](/docs/en/cloud-environments#network-access) for the access levels, the [default allowed domains](/docs/en/cloud-environments#default-allowed-domains), and the traffic that doesn't go through the allowlist. In a self-hosted environment, you restrict session egress at your own network boundary. When running with network access disabled, Claude Code can still communicate with the Anthropic API, which may allow data to exit the VM.
368368* **Credential protection**: in Anthropic-hosted environments, git credentials and signing keys stay outside the sandbox, and a proxy authenticates on the session's behalf with scoped credentials. In a self-hosted environment, your deployment supplies git credentials; see [Configure git](/docs/en/self-hosted-environments-deploy#configure-git)
369* **Network secrets**: in Anthropic-hosted environments on Pro and Max plans, keys you [add to a cloud environment](/docs/en/cloud-environments#add-network-secrets) stay outside the sandbox the same way, attached to matching requests after they leave the session. A self-hosted environment doesn't have network secrets, and Team and Enterprise plans don't have them yet
