Automated Filter Protections


DNS Floods

A DNS flood attack interrupts the DNS resolution. This causes the performance of your website, API, or application to no longer be sufficient or interrupts availability.


UDP Floods

Attackers use the functions of an open DNS or NTP resolver to overload a target server or network by increasing server requests to where the load is significantly higher than the original requirements.


HTTP Floods

An HTTP flood attack generates vast numbers of HTTP, GET or POST requests from various sources. They target the application layer and degrade the service or even cause it to go offline.

Other types of filter protection

SY flood, SYN-ACK flood, ACK/push flood, fragmented ACK, RST/FIN flood, synonymous IP, fake sessions, session attacks, misused or out of protocol attacks, peplay verb attacks, faulty application protocol attacks, UDP fragmentation attacks, VoIP flood, media data attacks, ICMP floods, fragmentation flood, ping flood, and many more.
