When we are swiping short videos late at night, grabbing limited edition sneakers, or video conferencing with overseas clients, behind us are countless CDN nodes relaying data in milliseconds. This seemingly silent industry is actually surging - DDoS attacks have evolved from simple traffic flooding to intelligent infiltration, and enterprises' demand for security and speed is like insatiable gluttony. 2025, the global CDN market scale exceeds $38 billion, and the competition among high-defence CDN providers has long surpassed the technical dimension and become a battle of trust and commitment.
