• What is DDoS protection software?

DDoS protection software is deployed on Internet hardware to mitigate DDoS/DoS attacks, especially for those attacks targeting on upper TCP/IP stack. Increasingly, sophisticated DDoS/DoS attacks come to application layer, like Slow HTTP Get&Post attacks. They are not easy to be detected and they consume victim servers with much less effort. To stop this kind of attacks, DDoS protection software is embedded in different layers of TCP/IP stack and gets full control of network flows. DDoS protection software works an extra security layer to enhance TCP/IP stack.

• Why use Anti DDoS Guardian?

Anti DDoS Guardian is DDoS/DoS protection software and as mentioned above, DDoS/DoS protection software provides Internet servers extra protection. Anti DDoS Guardian stops application layer DDoS attacks, SYN attacks, UDP flood, TCP flood, etc. Additionally, through Anti DDoS Guardian, users can view network activities in real-time and that gives users ability to monitor DDoS/DoS attacks. Therefore, users can change Anti DDoS strategies due to different DDoS attack patterns. Last, Anti DDoS Guardian can be easily installed on website servers and it is cost saving.

• How does Anti DDoS Guardian work on Windows servers?

Anti DDoS Guardian works as system software to protect Windows servers from DDoS/DoS attacks. There are tens of software components working together to achieve DDoS protection goal. The key part of Anti DDoS Guardian is a system device driver integrated into Windows TCP/IP stack, which allows Anti DDoS Guardian to check every ingress and egress network packets. In this way, Anti DDoS Guardian gets the full control of TCP/IP and keeps DDoS/DoS attacks (especially application layer DDoS attacks) away from Windows servers.

• How to stop layer 7 DDoS attacks?

Anti DDoS Guardian sits in the host servers' TCP/IP stack and counts TCP connections for each client computers. It monitors behavior of bad clients closely. If one client tries to access a host server with excessive TCP connections, Anti DDoS Guardian will stop it at the first place.

• How to use API to block IP addresses?

Many users ask for IP blocking API to integrate Anti DDoS Guardian to their systems and we do provide this API. With the easy-to-use IP Blocking interface, users can block bad IP addresses in real-time. Please click here to learn more.
