Anti DDoS Guardian - Protect your Windows server from DDoS attacks

Anti DDoS Guardian is high-performance DDoS/DoS protection software for Windows Servers. It places rate-based Anti-DDoS rules in the TCP/IP stack to block the most sophisticated DDoS/DoS attacks, such as Layer 7 (application layer) DDoS attacks, HTTP floods, UDP floods, and more. Anti DDoS Guardian provides powerful network monitoring tools that allow users to view all network traffic and detect DDoS in real-time. Once a DDoS attack pattern is identified, users can customize their own protection rules to defend against specific DDoS attacks. This lightweight yet powerful Anti DDoS protection software can be successfully deployed on Windows servers, in production environments, to secure websites against DDoS/DoS attacks. New version adds support for Windows 11 and Windows Server 2022.

anti ddos guardian awards
  • Rate-based DDoS protection to manage concurrent TCP connections, TCP and UDP packet rates, bandwidth, and more
  • Protocol-based Anti-DDoS firewall to block network packets by IP address, port, protocol and other TCP/IP factors
  • Block unwanted country IP addresses
  • Real-time DDoS/DoS monitor
  • Support white list
  • Support programming interface to import IP blocking list from third-party applications
  • What is DDoS protection software?
  • DDoS protection software is deployed on Internet hardware to mitigate DDoS/DoS attacks, especially against the 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 layer 7 (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 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 layer 7 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.
