Introduction
Distributed Denial-of-Service (DDoS) attacks pose a severe risk to businesses, disrupting services and damaging reputations. To combat these threats, Azure DDoS Protection Service offers robust, scalable solutions, helping organizations defend against large-scale attacks and ensure continuous operation. By leveraging advanced technology, Azure’s service mitigates DDoS risks and secures critical infrastructure.
Understanding DDoS Attacks
DDoS attacks occur when malicious actors flood a target’s server, network, or website with excessive traffic. This overwhelming influx of data exhausts the system’s resources, rendering it unable to process legitimate user requests. In some cases, DDoS attacks last for days, causing financial and reputational damage to the affected organization. As attackers continue to develop more sophisticated methods, defending against these assaults becomes increasingly challenging.
Azure DDoS Protection serves as a critical tool in this fight. By automatically detecting and mitigating DDoS threats, it enables companies to maintain consistent service and protect their digital assets from disruption. With DDoS attacks on the rise, robust protection has never been more essential.
