How do I get WBTC?

I'm curious, could you please explain to me how exactly do I acquire Wrapped Bitcoin, or WBTC? I've heard it's a way to use Bitcoin on Ethereum-based platforms, but I'm not quite sure how the process works. Is it through an exchange? Do I need to go through a specific protocol? And how does it ensure the safety and security of my assets? I'd really appreciate a detailed breakdown of the steps involved in obtaining WBTC.
