DDoS Testing Services
If your platform goes offline during peak traffic, attackers don't need sophistication—they just need volume. We simulate hostile, high-intensity traffic patterns to ensure your defenses can withstand a distributed attack without impacting legitimate users.
Hostile Traffic Simulation
Controlled Attack Testing
Defensive Validation
If your platform goes offline during peak traffic, attackers don't need sophistication.
They just need volume.
A sophisticated attack is dangerous, but a simple, high-volume volumetric attack is often just as effective at taking a service offline. Cyrex delivers DDoS testing services designed to simulate high-intensity, distributed denial-of-service conditions in a controlled, authorized environment. Using Cyrex Swarm™, we generate large-scale malicious traffic patterns to evaluate how your infrastructure responds under sustained hostile load. We test how your edge defenses, WAFs, and backend services handle the flood, ensuring you don't discover your weaknesses during an actual live incident.
We don't guess at resilience.
We measure it.
What Is DDoS Testing?
DDoS (Distributed Denial-of-Service) testing simulates malicious traffic targeting your critical endpoints. Unlike stress testing, which simulates legitimate user growth to find performance limits, DDoS testing specifically targets the robustness of your security architecture and defensive mitigation strategies.
Infrastructure Resilience: Can your network stack and load balancers withstand sustained, malformed traffic?
Availability Under Attack: Do your services remain reachable for legitimate users while the system is being flooded?
Rate-Limiting Effectiveness: Does your throttling logic successfully identify and drop malicious packets?
Traffic Filtering Accuracy: Does your mitigation strategy filter effectively without triggering false positives?
Auto-scaling Behavior: Does your system attempt to scale in response to an attack, or does it correctly identify the surge as hostile?
Failover Stability: If primary nodes are overwhelmed, does your secondary infrastructure maintain uptime?

DDoS testing simulates malicious traffic patterns designed to overwhelm specific system components
Why DDoS Resilience Matters
Online platforms - especially games and fintech systems - are constant targets. In today's digital landscape, your platform is a target not just because of the data it holds, but because of the disruption its downtime causes. Whether by competitors, disgruntled users, or opportunistic bad actors, high-value platforms are frequently tested for weaknesses.
Common Failure Points
System weaknesses under hostile traffic
API Gateway Overload: When malicious requests bypass your standard filtering and overwhelm your entry points.
Authentication Service Saturation: Forcing your auth servers to handle massive bursts of login attempts, locking out legitimate users.
Network Interface Exhaustion: Saturating your bandwidth pipes until genuine traffic can no longer reach your servers.
Load Balancer Instability: Causing your load balancers to crash or misroute traffic when they cannot process the volume of incoming packets.
Improper Rate Limiting: Identifying where your "throttling" is either too permissive or too aggressive, potentially blocking real users.
Firewall Misconfiguration: Finding rulesets that do not handle modern, distributed attack vectors effectively.
Cloud Scaling Delays: Forcing your auto-scaling groups to spin up new resources (at your cost) to handle an attack that shouldn't be scaled for in the first place.
DDoS resilience is not theoretical. A robust defense on paper is meaningless if it fails under pressure.
It must be validated under realistic, high-volume attack simulation.
Our Technology: Cyrex Swarm™
All DDoS testing engagements are powered by Cyrex Swarm™, our proprietary platform designed to handle massive concurrency. However, we do not believe in blind, indiscriminate packet flooding. We provide surgical, high-volume simulation that allows you to identify exactly where your defenses hold and where they fail.

How Our DDoS Testing Works
A structured, collaborative approach
What We Validate During DDoS Testing
- Infrastructure scaling under hostile load
- WAF (Web Application Firewall) configuration
- Rate-limiting rules
- Traffic filtering accuracy
- CDN behavior
- Edge protection logic
- Failover and redundancy design
- Service prioritization under saturation
When to Run a DDoS Test
If your platform has high visibility or financial activity, DDoS testing should be part of your resilience strategy
Who This Is For
If uptime directly impacts revenue and reputation, DDoS resilience must be validated
Resilience must be engineered — and verified
