DDoS protection refers to measures taken to defend against Distributed Denial of Service attacks, where multiple compromised computers flood a target, like a website, with excessive traffic. This overwhelming influx can cause the site to slow down or crash, making it inaccessible to legitimate users. To combat this, businesses often use specialized services or hardware that can detect and filter out malicious traffic. These solutions help ensure that the website remains operational, allowing users to access it without interruption, even during an attack. Effective DDoS protection is essential for maintaining online presence and reliability.
