Mail governance

The mailbox settings an attacker or a leaver abuses (forwarding, delegates, send-as), audited across every mailbox in every tenant. Read live, flagged when external, and remediable fleet-wide.

What's included

Auto-forwarding audit

Every mailbox's auto-forwarding state is read live across the fleet, and forwards to destinations outside the customer's domain are flagged per tenant. The classic quiet-compromise signal, checked everywhere at once.

Delegate audit

Mailbox delegates are enumerated per user, and delegates outside the organisation are flagged. External delegates can be removed in bulk, behind a dry-run preview and an explicit confirmation.

Send-as and aliases

Send-as identities and email aliases are audited per mailbox, so an identity a leaver left behind, or an attacker added, doesn't stay invisible. A dedicated alias audit covers every user across the fleet.

IMAP/POP posture

Per-mailbox IMAP and POP access is surfaced alongside the rest of the mail posture, so legacy-protocol exposure is visible before it becomes the way in.

Fleet-wide remediation

Disable external auto-forwarding across the fleet, remove external delegates, and push email signatures, each behind a dry-run preview, applied per tenant, and written to the audit log. Signature content is typed by the operator, never by the AI assistant.

Honest scan reporting

A mailbox whose reads failed counts as failed, and partial results are labelled partial. The scan is fail-closed by design. It never reports a false "all clear" over data it couldn't read.

Email authentication

SPF, DKIM, and DMARC checks live on the security page, alongside posture scoring. Mail governance here is about mailbox behaviour, not DNS.

Seeing where mail flows is included: the forwarding, delegate, and send-as audits above read live on every tier. Changing them in bulk (forwarding, delegate, and send-as remediation) is part of the Complete tier, so the tier you pick decides whether CrossTenant reports the problem or fixes it. See pricing.
