As 2025 drew to a close, Cloudflare remained at the forefront of cybersecurity, showcasing its formidable DDoS mitigation capabilities against an escalating tide of threats. The period around December 19, 2025, underscored the critical importance of these defenses, as Cloudflare successfully fended off hyper-volumetric attacks, including a massive campaign by the Aisuru-Kimwolf botnet that launched over 20 million requests per second.
Cloudflare's autonomous systems, boasting real-time intelligence and adaptive mitigation, continued to detect and neutralize an average of 5,376 attacks hourly throughout the year. These sophisticated defenses guard against both network-layer and HTTP DDoS attacks, a necessity given that overall attack numbers more than doubled in 2025. The company’s ability to withstand events peaking at 31.4 Tbps in mere seconds highlights their robust infrastructure. While specific pricing details for these services are generally tiered and depend on customer needs, the value of uninterrupted online presence against such severe threats is incalculable. Cloudflare's steadfast protection is essential for maintaining internet accessibility and service integrity in an increasingly hostile digital landscape.

Cloudflare is a technology company.
