Best Cloud DDoS Mitigation Software

Cloud DDoS mitigation software is used to provide global protection against distributed denial of service (DDoS) attacks. DDoS attacks bombard websites with traffic, which is traditionally delivered via “botnets" that are created by networked endpoints connected via malware. DDoS mitigation solutions defend against these attacks by monitoring web traffic and setting baselines for normal traffic loads. These cloud-based solutions are typically delivered as a software as a service (SaaS) offering and scale to provide complete protection, regardless of an organization’s size.

There are similarities and occasional overlap between cloud DDoS mitigation software and DDoS protection software. Those tools are traditionally used to protect local servers and networks from attacks, while cloud DDoS mitigation solutions are capable of protecting multiple disparate networks, servers, and applications.

To qualify for inclusion in the Cloud DDoS Mitigation category, a product must:

  • Filter and monitor incoming web traffic
  • Identify DDoS attacks and block incoming traffic
  • Support protection on a global scale
  • Provide comprehensive protection through a cloud-based service
