Introduction
DDoS (Distributed Denial-of-Service) Protection Tools are security solutions designed to detect, mitigate, and prevent large-scale traffic floods that attempt to disrupt websites, APIs, and online services. These attacks overwhelm infrastructure with malicious traffic, causing downtime, revenue loss, and reputational damage.
