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.




We own and operate our own servers, network gear and contract directly with numerous tier 1 providers. Our global network capacity is at 3Tbps and ever increasing.
