Anti-DDoS (Distributed Denial-of-Service Protection)
Anti-DDoS is a set of measures, technologies, and operational processes designed to detect, mitigate, and withstand distributed denial-of-service (DDoS) attacks, whose goal is to overload network channels, servers, or applications, and make a service unavailable to legitimate users.
Unlike simple filtering or “traffic limits,” professional Anti-DDoS protection is an infrastructure-level capability that combines network design, bandwidth reserves, intelligent traffic analysis, and human expertise.
What is a DDoS Attack in Practice?
A DDoS attack is not a single event, but a coordinated flow of malicious traffic generated from thousands or millions of compromised devices (botnets). The attack can target:
- Network layer (L3/L4)
Flooding channels with packets (UDP flood, SYN flood, ICMP flood) to exhaust bandwidth or connection tables. - Transport/session layer
Overloading stateful components such as firewalls, load balancers, or NAT devices. - Application layer (L7)
Sending seemingly legitimate HTTP/HTTPS requests that exhaust CPU, memory, or backend resources.
The danger of DDoS lies not only in its volume, but also in its asymmetry: the attacker spends minimal resources, while the victim’s infrastructure incurs a significant load and cost.
What Anti-DDoS Really Means (Beyond Marketing)?
True Anti-DDoS is not a single product, but a controlled system consisting of:
1. Excess Bandwidth and Network Capacity
- High-capacity transit channels with large headroom.
- Multiple Tier-1 upstream providers.
- Ability to absorb attack traffic without immediate saturation.
Without sufficient bandwidth, no filtering helps the channel fill before mitigation even starts.
2. Traffic Analysis and Filtering
- Continuous analysis of traffic patterns (baseline vs anomaly).
- Filtering based on:
- Packet characteristics
- Protocol behavior
- Connection rates
- Geographic or ASN-based patterns
- Separation of legitimate traffic from attack traffic in real time.
3. Infrastructure-Level Mitigation
- Filtering at the network edge, not on the attacked server.
- Blackholing or rate-limiting only when necessary and in a controlled manner.
- Anycast routing, when applicable, distributes attack traffic across multiple locations.
4. Human Control and Expertise
- Engineers who understand how real attacks behave, not just how filters are configured.
- Manual intervention when automated systems are insufficient.
- Ability to adjust mitigation strategy depending on:
- Type of attack
- Business logic of the client’s application
- Acceptable trade-offs (latency, filtering strictness)
This human factor is critical: incorrect mitigation can be more harmful than the attack itself.
Types of Anti-DDoS Protection We Provide
Depending on client needs, Anti-DDoS can be implemented at different levels:
- Basic Network Protection
Always-on protection against common volumetric attacks using excess bandwidth and standard filtering. - Advanced Network Anti-DDoS
Protection against large-scale L3/L4 attacks with adaptive filtering and traffic scrubbing. - Application-Aware Protection
Tailored mitigation for HTTP(S), APIs, streaming, gaming, and other application-specific traffic patterns. - Custom Anti-DDoS Architecture
For high-risk or high-profile projects:
- Dedicated filtering devices
- Segmented networks
- Anycast distribution
- Separate mitigation paths
What Anti-DDoS Is Not?
To avoid common misconceptions:
❌ It is not a guarantee that attacks will never happen
❌ It is not “blocking all bad traffic” without side effects
❌ It is not a checkbox feature or a simple firewall rule
❌ It is not fully automatic in serious cases
Anti-DDoS is about maintaining service availability, not about eliminating attacks.
Why Dedicated Infrastructure Matters for Anti-DDoS?
On shared or oversold platforms, DDoS protection often means:
- Automatic service suspension
- Throttling all traffic
- Passing the problem to the client
With dedicated servers and controlled infrastructure, we can:
- Apply mitigation without affecting neighbors
- Preserve legitimate traffic
- Maintain predictable performance and pricing
- Take responsibility instead of disabling services
Business Value of Anti-DDoS
For the client, Anti-DDoS means:
- Service availability during attacks
- Protection of revenue and reputation
- Predictable infrastructure behavior under stress
- Confidence that incidents are handled by engineers, not scripts
