- What monitoring alone tells you
- A domain exists, it resembles yours, it was registered on Tuesday. All true, and not yet a decision — most lookalikes never resolve to anything, and a queue that treats them equally is a queue nobody works.
- What validation adds
- Whether it resolves, whether a certificate was issued for it, whether it now serves a sign-in page copied from yours. The exposure is tested where it is safe and authorised rather than assumed from its existence.
- What termination adds
- A notice filed against whoever actually controls the name — the registrar, the host, the platform — and a case that stays open until it resolves rather than until it has been read. An alert closes when you acknowledge it. A removal closes when the page is gone, and those are not the same event.
