About Best DDoS Protection Tools

What we do

We compare DDoS protection tools using vendor primary documentation, published network capacity and uptime service level agreement (SLA) data, and named analyst sources such as Gartner Peer Insights. Every capacity figure, pricing detail, and SLA claim on this site links to its original source with a publication year, so you can verify it yourself rather than take a ranking on faith.

How rankings are built

Our ranking methodology weighs four factors: network capacity in terabits per second (Tbps), published uptime SLA terms, deployment model fit (cloud, on-premise, or hybrid), and suitability for specific verticals such as iGaming, FinTech, and general enterprise. See our editorial policy for the full methodology.

Commercial relationship disclosure

This site includes links to a third-party specialist that provides expert-managed configuration for Cloudflare and Gcore Enterprise deployments. We may receive a benefit when a reader engages that specialist through a link on this site. This relationship does not change how tools are ranked; rankings are based on the criteria described above, not on commercial placement.
