How does VNIS prevent these DDoS attacks?

The VNIS platform combines the power of infrastructure (Multi CDN) and advanced security technology (Multi WAF) to help protect websites, applications, and APIs from high-volume DDoS attacks and DDoS attacks on the Application layer.

Currently, VNETWORK has also just upgraded 12 more WAF servers, estimating that each WAF has the capacity to handle more than 800,000 requests.

VNIS also has a smart Multi CDN load balancing system calledAI Load Balancingand a WAF:Scrubbing Centerload balancing system that helps prevent large and sophisticated DDoS streams from many countries.

Besides, VNIS also works closely with network security monitoring centers (SOC - Security Operation Center) in many countries and territories, helping to detect probing attacks early and proactively prevent them when they are detected. The attack is still in its infancy.

VNETWORK brings advanced security to businesses, helping them feel secure in doing business on the internet environment. Therefore, we also support the implementation of service quality commitments (SLAs) for domestic and foreign customers.
