What is Coinbase Prime?

Could you elaborate on what Coinbase Prime entails? As a cryptocurrency and finance professional, I'm curious to understand the nuances of this platform. Is it tailored specifically for institutional investors? What kind of services does it offer that differ from Coinbase's regular platform? Are there any unique features or benefits that make it stand out? Furthermore, how does Coinbase Prime ensure the security and integrity of its services, given the volatile nature of the cryptocurrency market?
