But now that Peter is the high-profile, media-centric head of a major tech corporation--as opposed to being a half-broke freelance photographer that nobody gives a damn about--he doesn't have the luxury of dropping everything at a moment's notice and disappearing to become Spider-Man, if some teched up, costumed whack job attacks him in the middle of a TV interview or a stockholders meeting. So having a visible, high-profile protector gives him cover to fend off the actual attack as it occurs. And, if the attacker manages to escape the initial confrontation, then he and his "bodyguard" can team up later--after the cameras and observers have gone--to track the bad guy down and finish him off.
So, basically, Mockingbird is Peter's beard. Another reason why this sounds like a bad idea.
