Security standards; I think this is the major checks before investing with any CEX platform as a user. Usually it’s better to check out for the hack history and prior security bridges.
You'll struggle to use any exchange if you go looking through their history of hacks and security breaches, because most of the 'top' exchanges you will find have been hacked in the past, and funds and data stolen.
You cannot really check the 'security standard' of a centralized exchange, though i reckon many of them do not spend funds on security, based on how they successfully get hacked. But for your own good, it is better to stick with the popular exchanges
andbut don't store your funds in there.
