Since our inception DOSarrest was created to stop DDoS attacks, we are not an add-on service to another existing business. We are focused on HTTP/HTTPs and protecting websites, API's and mobile application servers on TCP ports 80 and 443. We are not generalists. Should you require protection for a complete data center, we have a special product for that too, Our Data Center Defender service can protect all of your infrastructure.



All of our cloud-based services use our in house big data analytics engine, to provide powerful real-time and historical statistics for our customers. Our graphical displays are all interactive allowing customers to pick and choose the metrics they want to see instead of irrelevant information that's just noise.
