Put some kind of phase shift protection for the AI

[Musketman12]

You could also replace the grilles that are all around the AI upload/chamber with phase-shift disrupting laser emitters.
Can't pass through them while phase-shifting, trying to do so ends the phase-shift prematurely, occasioning some brute/brain damage and/or stunning from being suddenly space-shredded, and making a decent amount of noise alerting nearby people and the AI of the failed intrusion.

This is what I was thinking, just something where it will just stop the wizard from phase shifting through all of the AI's defenses and making the AI completely defenseless against wizards.
