The AT&T DDoS Defense service offers comprehensive cloud-based surveillance for volumetric distributed denial of service (DDoS) attacks, employing in-depth traffic analysis to potentially trigger countermeasures that prevent harmful traffic from infiltrating your network. Customers can benefit from fully managed proactive or reactive DDoS protection by contacting the AT&T threat management center to initiate mitigation efforts, or they can depend on alerts sent directly to AT&T when harmful traffic targeting specific IP addresses within the customer's network is detected. This system ensures seamless activation and operation of essential business applications, allowing legitimate traffic to flow uninterrupted. In-depth traffic analysis is essential for spotting irregularities, enabling the diversion of malicious traffic to scrubbing facilities for blocking. The fully managed service also provides email notifications regarding critical alerts, advisories, and any attacks. Additionally, users can access a web portal for detailed service and status reports, while the managed service is capable of monitoring a designated range of IP addresses, ensuring that all potential threats are closely watched. This comprehensive approach not only enhances security but also fortifies business resilience against cyber threats.
