ACK flood protection: mitigate TCP DDoS attacks without blocking real sessions
An ACK flood targets the part of TCP that should normally look legitimate: packets that appear to belong to established connections. The problem is not only bandwidth. High packet rate, spoofed ACKs and asymmetric paths can exhaust firewalls, load balancers, routers or servers before the application understands what is happening. Good mitigation must reduce the flood early while preserving real sessions that already exist.
Read article
DDoS amplification attack explained: why small requests can become massive floods
A DDoS amplification attack uses third-party services to turn small spoofed requests into much larger responses sent to the victim. The target does not only receive traffic from the attacker. It receives reflected traffic from many legitimate servers on the Internet, often using UDP-based protocols. Understanding amplification is essential before choosing protected IP transit, a scrubbing model or a gaming proxy, because the failure point is usually upstream capacity rather than the application itself.
Read article
DNS amplification DDoS mitigation: protect exposed infrastructure without blocking legitimate DNS
DNS amplification is one of the most common UDP reflection patterns because DNS is widely available, response sizes can be larger than requests and spoofed traffic can be directed at a victim. The mitigation challenge is precise: blocking all UDP/53 may stop a graph, but it can also break DNS-dependent services. A serious design separates open resolver abuse, reflected floods and legitimate DNS traffic before the attack reaches the customer edge.

SYN flood protection: mitigate TCP DDoS attacks without blocking real connections
A SYN flood is not only about sending many packets. It abuses the TCP opening phase to create pressure on connection queues, stateful firewalls, load balancers and exposed servers. Effective protection must filter early, avoid state exhaustion and keep legitimate users able to establish sessions.

UDP flood mitigation: stop a UDP DDoS without breaking legitimate traffic
A UDP flood is not just “a lot of UDP packets”. Depending on the service, it can saturate a link, exhaust a firewall, trigger useless responses or disrupt a real-time protocol such as gaming, VoIP, DNS, VPN or a UDP-based application. Good mitigation is not about blocking UDP everywhere. It is about separating obvious noise from useful traffic, protecting upstream capacity and delivering clean traffic with low latency.

Volumetric vs application-layer DDoS: differences, risks and the right mitigation model
A volumetric DDoS attack and an application-layer DDoS attack do not break a service in the same way. The first mainly tries to saturate network capacity, ports, packet rate or upstream paths. The second targets service logic: HTTP, APIs, authentication, game proxies or expensive requests. Understanding the difference helps choose a mitigation design that actually works instead of relying on a generic Anti-DDoS promise.

How to choose an Anti-DDoS provider without getting trapped
Choosing an Anti-DDoS provider should not be reduced to a Tbps number or a promise of unlimited protection. What matters is how traffic enters the mitigation layer, how it is filtered, how clean traffic is delivered back, what visibility you get during an attack and which limits actually exist.

Asymmetric routing and Anti-DDoS: what you need to know
Asymmetric routing is not automatically a problem in Anti-DDoS.
