Network-layer DDoS attacks are increasing, prompting security teams to reevaluate their L3 DDoS mitigation strategies. To address this issue, Cloudflare has introduced new functionality for its on-demand Magic Transit service called flow-based monitoring. This feature allows the detection of threats and notifications to customers when they are under attack so that they can activate Magic Transit for protection. Magic Transit is a solution offered by Cloudflare to secure and accelerate networks at the IP layer, providing DDoS protection, traffic acceleration, and other network functions delivered as a service from every Cloudflare data center. With its global network and fast time to mitigate attacks, it offers comprehensive protection without compromising performance.
