Case Study: Weebly achieves robust protection against large-scale, sophisticated DDoS attacks with F5 Networks' Silverline DDoS Protection

F5 Silverline DDoS Protection Safeguards Weebly against the Largest and Most Sophisticated DDoS Attacks

Weebly, a website builder used by more than 20 million people and receiving over 175 million unique visitors a month, faced increasingly large and complex Distributed Denial of Service (DDoS) attacks that began to challenge its internally built mitigation. To add a secondary layer of defense, Weebly evaluated options and selected Defense.Net’s DDoS SWAT service (acquired by F5 Networks) and adopted F5 Silverline DDoS Protection as a backup to its in‑house infrastructure.

F5 Networks deployed its cloud‑based F5 Silverline DDoS Protection to run behind Weebly’s internal controls, bringing distributed scrubbing centers, advanced mitigation techniques and a team of DDoS experts; the service was installed in hours and immediately began protecting traffic. The result: uninterrupted mitigation and analysis, protection against attacks at least as large as 41 Gbps, no upfront on‑premises investment, and confidence that Weebly can withstand larger future attacks.
