A DDoS attack is carried out with the help of several infected computers asking to access your network's internet resources at the same time. This leads to a slowdown in your websites and applications. It may not only cause financial loss but it can also lead t a dip in customer loyalty. Robust DDoS software or services are needed to protect your organization against any such malicious attacks.
DDoS protection software and services work to prevent such attacks on your websites and web resources by constantly monitoring the web traffic and setting a specific baseline for normal traffic inflow. A soon as an abnormal traffic flow is detected by the DDoS software it is diverted to a controlled source thereafter.
