Should Unity be used for security sensitive games?

I’m well aware Unity would be great for building a game. But I haven’t found much information on how secure it actually is, how secure is it? I have plans for a game and security will be essential for this game. Thanks.

Absolutely nothing is secure if it’s running locally; that’s how computers work, nothing to do with Unity. If you need security the game must run on the server. This doesn’t prevent you from using Unity for the client of course.
