Best DDoS Protection Software

Distributed denial of service (DDoS) protection tools help secure websites and applications and prevent DDoS attacks. DDoS attacks bombard websites with traffic, which is traditionally delivered via “botnets" that are created by networked endpoints connected via malware. DDoS protection solutions prevent these kinds of attacks by monitoring web traffic and setting baselines for normal traffic loads. If an incoming traffic flow accelerates rapidly, web filters will identify abnormal events and redirect traffic to a controlled source.

Companies use DDoS protection tools to proactively maintain steady site functionality and prevent sudden site delivery failures caused by the rapid influx of traffic. Many content delivery networks come with additional DDoS protection features or modules. Since they often host websites and content, ensuring smooth delivery is one of the vendor’s main objectives.

To qualify for inclusion in the DDos Protection category, a product must:

  • Filter and monitor incoming web traffic
  • Limit traffic flow or set traffic baselines
  • Identify DDoS attacks and block incoming traffic
  • Provide a traffic management dashboard
