What people are saying about
Anti DDoS Guardian
Anti ddos guardian is amazing......There is no other solution that I've seen that actually worked well......
— Daniel Bowen
I have been using it since 2012......when I used Windows Server 2003, it worked very effectively. However, recently, the service provider has stopped supporting the 2003 version and encouraged an upgrade to Windows Server 2012......(from an email received in 2023 )
