Exploit Patching

Hi there,
I am a developer for Five Guys (upcoming ROBLOX cafe group) and during the launch today, we have had multiple exploit attacks.

We have done really everything we can in attempt to stop these exploiters such as limiting age on our game, (the current age limit on our game is 15) and using scripts like anti boots but somehow these exploiters keep breaking in.

Does anyone have any ideas to increase our game security? If so, please let me know.
