Anti DDoS Guardian - Protect your Windows servers from DDoS attacks.

Anti DDoS Guardian is high performance Anti DDoS software for Windows Servers. It manages network flow and keeps attack traffic out. Anti DDoS Guardian protection can deal with most DDoS/DoS attacks, including Windows Remote Desktop brute force password guessing attacks, SYN attacks, IP flood, TCP flood, UDP flood, ICMP flood, slow HTTP DDoS attacks, etc. This Anti DDoS firewall limits network flow number, client bandwidth, client TCP connection number, UDP/ICMP packet rate, and most importantly, it controls TCP half-open connection which is effective to stop SYN attacks. Anti DDoS Guardian can be successfully deployed on Windows website server machines, in a production environment, to easily ban country IP addresses with Apache's .htaccess files. It protects online servers, such as Apache servers, IIS servers, online game servers, mail servers, FTP servers, Camfrog servers, VOIP PBX and SIP servers and other Internet servers. In addition, this Anti DDoS software serves as a lightweight firewall with TCP/IP rules and the rules are based on IP address, port, protocol, and other TCP/IP factors. It supports IP black list, white list, exceptional rules, log files, network activity displaying, IP address looking up and other powerful features. Anti DDoS Guardian is fully compatible with Windows 2000, XP, 2003, 2008, Vista, Windows 7, Windows 8 and Windows 2012, in 32-bit and 64-bit. Version 3.0 adds protection against RDP brute force attacks and supports Windows 8 and Windows 2012.

How does Anti DDoS Guardian work?

First of all, Anti DDoS Guardian works under NDIS (Network Driver Interface Specification) layer, which is the first layer that incoming network traffic passes through. Since NDIS filtering occurs at such a low level, Anti DDoS Guardian can filter each incoming and outgoing network packet. When a packet is received or sent from the user's computer, this DDoS protection will check it and determine to drop or allow it based on Anti DDoS policy, IP list and firewall rules.

Second, Anti DDoS Guardian manages network traffic in the form of TCP connections and network flows. It limits the number of TCP connections of each client, the bandwidth of each client, and the number of network flows that an Internet server can hold. This Anti DDoS firewall restricts UDP and ICMP packet rate, and most importantly, it controls TCP half-open connection which is effective to combat SYN flood.

Third, this Anti DDoS software utilizes IP list file to protect Internet servers. Particularly, country IP addresses in the form of Apache's .htaccess file or other P2P IP filter file can be imported to ban country IP addresses. IP list file can be updated periodically by configuring IP list management. In addition, both IP black list and white list are supported.

Last, firewall rules based on TCP/IP protocols can be used in Anti DDoS Guardian. Users can specify a rule by IP address, port, protocol, and other TCP/IP factors. This is the third layer to protect Internet servers from being attacked. 

How to block brute-force password guesssing attacks?

It is observed that most brute force attacks subvert Internet servers by excessive password attempts. Anti DDoS Guardian was designed to limit the number of TCP incoming connections within a certain period of time. In this way, most brute force attacks are blocked.

Comments by Anti DDoS Users

"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......"

"anti ddos guardian blocks ddos attacks generally......so it does the required job......before i found your program , my friend paid 300$ to ......but you know , their programs made setting up the program hard for user i think......"

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 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 ( Windows 2000, 2003, 2008, Windows 7, Vista, both in 32 bits and 64 bits ) , 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.

Who use Anti DDoS Guardian?

• Website masters who want to protect HTTP servers, proxy servers, online game servers, Email serves, FTP servers, Internet forum servers and VoIP PBX SIP servers.

• IT administrators who need to set special TCP/IP protocols based firewall rules.
