Unleash UDP amplification & TCP bypass attacks against your own infrastructure. Validate firewall resilience with up to 1.5 Tbps of raw network capacity.
Layer 4 (Transport Layer) stress testing targets the TCP and UDP protocols directly - the backbone of all network communications. Rather than hitting a web application, L4 attacks saturate bandwidth, exhaust connection tables, and overwhelm stateful firewalls at the network edge.
Our platform provides the industry's most comprehensive suite of L4 methods, powered by a 1.5 Tbps+ network with global Points of Presence. Whether you are testing a game server, VPS, or enterprise firewall, our tools replicate real-world DDoS scenarios with precision.
UDP Amplification
DNS, NTP, SSDP, Memcached and custom amplification vectors generating massive traffic bursts.
TCP Bypass Methods
Crafted TCP sequences that establish valid connections, bypassing most stateful firewalls and anti-DDoS solutions.
1.5 Tbps Capacity
Our network is capable of generating sustained multi-Tbps traffic. No throttling on premium plans.
Custom PPS & Concurrency
Fine-tune packets-per-second and concurrent attack threads to simulate specific threat models.
Attack Scheduler
Schedule stress tests in advance - run them during maintenance windows or off-peak hours automatically.
API Access
Fully documented REST API for integrating tests into your CI/CD pipelines or custom dashboards.
Our Layer 4 suite includes - but is not limited to:
New methods are continuously developed and pushed to the platform. All methods are tested in-house before release.
Game Server Hardening
Validate your game server's anti-DDoS protection before going live. Identify bottlenecks in UDP handling and connection management.
Firewall & ISP Testing
Confirm your upstream provider's scrubbing capabilities and measure how your firewall rules hold up under sustained flood conditions.
Security Research & Education
Reproduce real DDoS attack patterns in controlled lab environments for academic research or professional training.
