Core-Security already have a range of high end products that secure the Apple IMac range. These include our 6mm Lapcable, or the Imac Clamp system, both of which are a cable based solution. While the Imac Clamp system would offer a form of security for the Imac Pro. It will not prevent the removal of the Mac from the stand.
Core-Security have developed the IMac Security Stand to include a stop onto the locking disc. This solution prevents the tilting of the stand, which in turn prevents a card being inserted into the stand and removal of the Mac from the stand.
Unfortunately the product does not have a security slot where you could fix a Core Lapcable to give it a form of security.
However this would not solve the problem of theft.
By tilting the product forward you can insert a card to expose the fixing screws, and simply remove the IMac Pro from its stand.
