Security

Your code and secrets stay yours.

Agents get a computer of their own and use your accounts without seeing a password. Here is how.

01

Every workspace is its own microVM

Your agents never share a machine with anyone else’s.

  • Each workspace runs in an isolated microVM with its own kernel, memory, disk and processes.
  • Workspaces share nothing unless you attach the same shared volume to them.
  • Your machine and project templates are private to your account.

02

Logins stay yours

Agents use your accounts without ever seeing a password.

  • Import from 1Password, Bitwarden, macOS Keychain or hsec: sent end to end, Shardflux only relays encrypted bytes.
  • You approve each login: allow once, or always for this project.
  • Remembered logins are encrypted with AWS KMS, filled straight into the page and logged on every use.

03

Secrets are encrypted

Environment secrets reach only the project they belong to.

  • Imported secrets are encrypted with AWS KMS; only that project’s workspaces can load them, and every load is logged.
  • Tool output that touches a bound secret is redacted before it is stored. If redaction fails, the call is dropped.
  • Claude and Codex sign-ins are delivered privately when an agent starts. Your laptop’s login stays separate.

04

Private by default

Nothing in a workspace is reachable until you share it.

  • Every port is private. Previews and live desktops open through private links that expire.
  • Outbound traffic can be limited to an allow list of destinations per project.
  • All connections to the service use TLS.

05

Account protection

Sensitive actions ask for proof that it is really you.

  • Two-factor sign-in with an authenticator app, and recovery codes.
  • Exports, deletions and security changes need a fresh confirmation (step-up).
  • Owners and admins manage who is in your organization.
  • An audit log records requests and their results, and you can export it.

06

Your data

Where it lives, who processes it, and how it is deleted.

  • Workspaces and the API run in AWS US West (Oregon).
  • No advertising or analytics cookies on the site or the console.
  • Delete workspaces at any time. At the end of the service, you choose return or deletion.
  • A Data Processing Addendum covers your content, with 30 days’ notice before a new subprocessor.
