Most powerful service of distributed filtration consists of high-performance clusters and is located in the Netherlands, Germany and Russia. Core components of filtration are located in the data centers of the operating level. DDoS-GUARD company accepts traffic directly from operators of TIER1 (Level3, TiNET, TTK, RETN), major European points of traffic exchange (DECIX, AMSIX, NL-IX, DATA-IX, MSK-IX, GE-IX), major local communications providers and peering partners. The total network capacity is 1.5 Tbps, and we are continuously working on increasing these indicators. By 2015 we are planning to expand the traffic filtration network to Asia and Northern America to ensure more comprehensive coverage of the attacking traffic sources. Such network structure allows accepting and processing traffic in the immediate proximity from its sources and reliably protect the end user from distributed attacks of any intensity.
