Hardening the chat and file-sharing platforms Kestrel Logistics' dispatchers, warehouses and outside carriers share, on the collaboration defense stack: eight layers from identity, access and sharing through apps, data and guests to threats and monitoring; a dispatch channel where an impersonating 'CFO' account is suspended, a disk-image attachment is blocked, a card number is stopped by DLP and a shipment manifest is shared only with named people; and the admin console clean-up, from a contractor still active 548 days after leaving to an exposed bot token rotated and logs from three platforms centralized.
