A Purple Team is a cybersecurity approach that combines two important groups: Red Teams (who test security by acting like hackers) and Blue Teams (who defend against attacks). Think of it like a practice game where one group tries to break in while the other tries to stop them, but they work together to make the company's security stronger. It's similar to having a security consultant who both tests your locks and helps install better ones. This collaborative approach helps companies find and fix security problems more effectively than having separate attack and defense teams.
