DDoS保護已成為許多內容傳遞網路(CDN)和網絡託管平台不可或缺的一部分，軟件廠商之間就向數據中心市場提供DDoS保護的解決方案互相競爭。由於其更廣泛分佈的伺服器位置，內容傳遞網路具有最佳改道流量並隔離不良請求式樣的整體能力。內容傳遞網路亦提供更多工具，利用類似在網絡防火牆或軟體定義網路（SDN）使用的策略，讓網站管理DNS設置以防止DDoS。大多數反DDoS工具掃描從漏洞而來有已知不良式樣的流量請求。
並非所有網站都需要DDoS防護，但如果數據中心的其他域名被針對，特別是在使用共享網頁伺服器的話，即使是小型獨立企業，亦可能會受到網站服務中斷的影響。由於對在共享CentOS伺服器上託管的其中一個域名作出DDoS攻擊可能會影響數千個網站，網站託管公司需要對其反DDoS保護的能力進行評估。
