I would like to learn about the leading Distributed Denial-of-Service (DDoS) protection tools that organizations use to defend websites, APIs, and network infrastructure from large-scale traffic attacks. Which platforms—such as Cloudflare DDoS Protection, Akamai Prolexic, AWS Shield, Microsoft Azure DDoS Protection, Google Cloud Armor, Imperva DDoS Protection, Radware DefensePro, NETSCOUT Arbor, F5 Distributed Cloud DDoS Protection, and Fastly—are most widely used for mitigating volumetric, protocol, and application-layer attacks, and how do they compare in terms of real-time traffic analysis, automated mitigation, global scrubbing capacity, integration with WAF/CDN services, reporting dashboards, scalability, pricing models, and ease of deployment for enterprises, cloud environments, and high-traffic web applications?
