The best thing about this software is that it's completely free of charge. There are no premium features, just the basic option is there in the package which I really like a lot. It has all the features that one can ask for, if any additional feature is required then it would be available in paid versions too but as far as my experience goes it gives a decent solution to the problem and you don't have to pay extra for those features. It doesn't give much support regarding its usage or anything but just go ahead with the installation process. If you are looking out for an anti-DDoS solution for free then this is the right choice. We were facing DDoS attacks from hackers who were trying to hack into our database so we thought about purchasing some expensive DDoS protection service but it was not worth the price. And yes, I do recommend trying out this service. As per our requirement it protects us from DDoS attacks and also.
