*Wait until you have a full rolling boil before adding your hops
*Get a bigger kettle
*Become better at recipe design to limit intense protein/polyphenol interactions
I have no worry of boilovers. I don't mist my wort, nor do I add my bittering hops slowly, or use ferm cap. If you do experience excess foam that looks like it will boilover, turn off the heat immediately. The reduction of heat will cause the foam to subside. Of course you have to turn it back on, but this is the best way to prevent a mess if you sense a mess.
