About this interactive
There is usually a long delay between when a device's firmware is built and when you deploy it: manufacture, shipping, warehouses, the store. During that time the vendor keeps releasing fixes, so a brand-new device is rarely an up-to-date one.
The first hardening step is to update it. Compare the installed firmware or software against the vendor's current release. If it is behind, with superseded firmware or missing published fixes, patch it before it goes live, so it does not spend its first days on the network with known holes open. If it has already been brought to the vendor's latest version, it is current and ready. To sort a card, ask whether the installed version is behind the vendor's latest or already matches it.
