In the first half of 2026, Cloudflare detected a 519% surge in hyper-volumetric DDos attacks across its network. These attacks were driven heavily by DNS and CLDAP reflection vectors. This report breaks down how major geopolitical conflicts reshaped the global cyber threat landscape.
In our post about Project Glasswing, we made the argument that the architecture around a vulnerability matters more than the speed of the patch. Here we walk through what that architecture looks like, the threats it defends against, and how we run it ourselves as Cloudflare's customer zero.
Cloudflare customers can now use Cloudforce One threat intelligence directly within the WAF to block high-risk traffic. By using new cf.intel fields, security teams can automate protection against specific threat actors and targeted industries in real time.
There has been a fundamental shift toward industrialized cyber threats, highlighted by a record 31.4 Tbps DDoS attack and sophisticated session token theft.
