The path of your traffic
How DDoS protection works
Traffic first passes through the Frankfurt scrubbing center. Malicious packets stop there; only clean traffic reaches your server.

Attack vectors
Which attacks it covers
DDoS protection filters volumetric (Layer 3/4) attack types at the source.
UDP Flood
Flooding bandwidth with spoofed UDP packets.
SYN Flood
Exhausting resources with half-open connections.
ACK Flood
Choking processing with invalid ACK packets.
DNS Amplification
Multiplying traffic via open resolvers.
NTP Amplification
Abusing time servers as reflectors.
TCP Reflection
Filling the link with reflected SYN-ACK floods.
DDoS protection detects and filters distributed attacks at the network edge before they reach your server. At uLCloud it is on by default — no add-on, no configuration.
