Data leak detection is the practice of discovering when sensitive data has been exposed, whether through a misconfiguration, a breached database, or credentials harvested by malware. Speed matters, because leaked data is monetized quickly once it circulates.
Not every leak is a dramatic database dump. Infostealer logs quietly expose credentials and personal data at massive scale, and recycled or inflated dumps can cause panic if not analyzed carefully. Good detection separates real, fresh exposure from hype.
