Filtering Attacks Based on One-Click Rate Limiting Rules

As DDoS attack methods become increasingly sophisticated, UDP reflection attacks have emerged as a major threat to enterprise cybersecurity. You must effectively defend against these attacks, but manually configuring protection rules is often complex and time-consuming.

CNAD Advanced provides a one-click enablement feature for common filtering rules. You can easily enable UDP reflection protection and other key filtering rules. In addition, you can quickly deploy traffic rate limiting rules, simplifying the configuration process and improving mitigation efficiency.
