Departing employees
Theft climbs for months before anyone resigns and spikes in the hours after they decide to. By the time the notice reaches you, most of it has happened.
Security or legal at a company whose value sits partly in what its people know: the customer list, the pricing logic, the model weights, the playbook.
The trigger today is the resignation email, which arrives after the copying is finished. DLP fires on one bulk export and stays quiet through three weeks of ordinary-looking downloads. By the time you look, the laptop has been wiped and reissued, the mailbox is purged and the logs have rolled.
An exit review on every departure, opened by the resignation and concluded in writing before the last day. Most conclude with nothing of concern. The rest name the files, trace where they went, and carry an examiner’s signature.
