"I must really compliment you on your work. Anti ddos guardian is amazing......It works better than anything we've used......It's too cheap......People will offer a lot more for this kind of protection......Especially once they know how well it works......There is no other software that I've seen that actually worked well......We've had trouble with DDoS attacks with our game servers for a very long time......We've used hardware mitigation and other mitigation services......But none of them ever worked......"

Stop DDoS attacks


How to stop DDoS?

Anti DDoS Guardian stops DDoS attacks by several settings, such as the maximum number of TCP connections, bandwidth of each client computer, the maximum number of incoming UDP/ICMP packets per second,  and the maximum number of incoming TCP concurrent half-open connections, etc. These functions can be successfully used to block many DDoS attacks.

How does Anti DDoS Guardian detect RDP brute force attacks?

Most Internet Windows servers suffer RDP password brute force attacks without being noticed. Anti DDoS Guardian reads the Windows system RDP failed logging information in Real-Time and blocks those IP addresses which attempt to log on users' servers with random usernames and passwords.

How to use Anti DDoS Guardian as an IP blocker to import IP list from other applications?

Users can use command "IPBlockerDemon.exe importlist block (or allow) filename" to import IP blocking list. This feature is particularly useful for those applications which can create bad IP address list from suspicious network activities. Once an IP list file is created, users can use the above command to apply the new IP blocking list at once.

How to block country IP addresses?

In some cases, we need to block country IP addresses, especially for website masters who want to protect Windows servers, such as HTTP servers, mail servers, FTP servers, VOIP PBX and SIP servers. Anti DDoS Guardian can be successfully used by website administrators on Windows servers machines, in a production environment, to easily ban traffic from whole countries. Users can simply download Apache's .htaccess files which can be easily downloaded from a lot of websites and then import the .htaccess files.
