I use this card's effect on one of my opponent's Digimon, which they then digivolve. Can it now attack and block?
No, it can't.

Does this card's security effect also prevent my opponent's suspended Tamers from unsuspending during their unsuspend phase?
No, this card's security effect only affects Digimon. Your opponent's Tamers unsuspend as normal.
