Distributed denial of service (DDoS) attacks can cripple an organization, a network or even an entire country. DDoS attacks make up a considerable percentage of security threats, and recent attacks have been larger and more complex than ever.

While there are some things security teams can do to lessen the impact of DDoS attacks, the growing sophistication of such attacks has sparked strong growth in the market for DDoS solutions. Research firm IDC expects the DDoS prevention market to grow 20 percent each year through 2021.

The vendors listed here scored well in the Forrester DDoS Wave or the Quadrant Knowledge Solutions DDoS report – or both. In addition to handling traditional DDoS attacks, they incorporate cloud, mobile and IoT features. Each vendor summary links to a detailed analysis, including target markets and use cases, features, metrics, intelligence, use of agents, security certifications, product delivery (cloud, software or hardware) and pricing. There's also a chart at the bottom of this article comparing the solutions.

Core DDoS solution features include detection of the early stages of an attack, the scale to absorb the volume of traffic, and the ability to mitigate the source of the attack. This can be done via static or custom rules, or through an evolving set of defensive actions as the attack morphs toward additional targets.
