# Gates

Gates are application-specific firewalls. If you have three applications you want to protect, Application X, Application Y, and Application Z, you would create 3 Gates in VYSP.AI. This would create an input flow and an output flow in each of the 3 gates that you can use to monitor and/or flag inputs from the user and outputs from your AI applications.
