Is Coinbase a legit company?

Could you please clarify for me whether Coinbase is indeed a legitimate and trustworthy company in the cryptocurrency industry? I'm considering using their platform for my transactions but want to ensure that they have a solid reputation, robust security measures, and are fully compliant with regulatory requirements. Additionally, I'd appreciate it if you could provide any insights into their customer support and any potential drawbacks that I should be aware of before making a decision. Thank you in advance for your assistance.
