Distributed Denial of Service (DDoS) attacks have evolved into one of the most serious cybersecurity threats facing businesses today. With the average cost of website downtime reaching $2 million for enterprises, and attacks capable of reaching unprecedented scales of over four terabits per second, organizations can no longer afford to view DDoS protection as optional.
Understanding Modern DDoS Threats
Modern DDoS attacks have shifted from simple traffic floods to sophisticated application-layer strikes. Today’s attackers use AI, residential proxies, and advanced botnets to target critical business systems like payment processors and login pages while mimicking legitimate user behavior.
Adequate DDoS protection provides business continuity, protects revenue, preserves brand reputation, and reduces incident response costs. When selecting a solution, prioritize real-time detection, multi-layer protection, scalability, seamless integration, and accurate traffic analysis.
