Customer Isolation

Files.com separates customers' data and configuration while running on shared infrastructure. Access to one customer's site does not grant access to another customer's site. Each operation must be authorized for the site and resources it affects, including access to file contents and background work performed on the customer's behalf.

This is logical separation through access controls. Sharing a service or storage system does not give customers access to each other's data, and creating a Site or Workspace does not allocate dedicated physical infrastructure.

Authorized Connections Between Sites

Customers can authorize connections between their Sites to exchange files. Being an administrator of one Site does not by itself authorize access to an unrelated Site. Access Across Sites and Storage explains the permissions and controls that apply when customers choose to connect their Sites or expose connected storage.

Subdomain Reuse

A Files.com subdomain is an address assigned to a site, not a permanent identifier of the customer who first used it. Claiming a previously used subdomain does not transfer the former site's files, users, or permissions. Connections to that address can nevertheless reach a different customer's site after the name is reassigned.

Preserve an old address while people or integrations still rely on it, and update their destinations before releasing it. A familiar address alone does not establish that it still belongs to the same customer. Custom Subdomain explains availability, expired-trial reassignment, preservation, and release.
