This document is a technical report that examines the persistent vulnerabilities in DDoS protection solutions despite significant investments by organizations. It outlines the reasons why even basic DDoS attacks can bypass established defenses, leading to service disruptions. The report is based on extensive analysis, including over 100,000 hours of annual attack simulations, which reveal that all deployed DDoS protections have unnoticed gaps that can be exploited by attackers. It details the nature of DDoS vulnerabilities, contrasting them with other types of cyber vulnerabilities, and emphasizes that effective DDoS protection requires a multi-layered approach. The report also discusses the importance of continuous validation and proactive testing of DDoS protections to identify and remediate vulnerabilities before they can be exploited. Additionally, it highlights the unique characteristics of DDoS vulnerabilities and the need for organizations to focus on specific attack vectors that pose the greatest risk to their services.
