Is Worldpay safe?

I've been considering using Worldpay for my online business, but I'm hesitant to do so without knowing if it's safe. Can you tell me more about Worldpay's security measures and if it's a reliable option for processing payments? I've heard mixed reviews about it, so I'm looking for some clarification from someone who knows the industry well. Is Worldpay truly secure and trustworthy? What kind of protection does it offer for both merchants and customers?
