Avydos DDoS Threat Simulation is a commercial threat simulation tool by Avydos. Leonidas is a free threat simulation tool. Compare features, ratings, integrations, and community reviews side by side to find the best threat simulation fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams responsible for DDoS resilience will benefit most from Avydos DDoS Threat Simulation because it's one of the few platforms that actually measures filter quality and detection speed rather than just simulating attacks. The DRS-Score standardizes your results across vendors and infrastructure, which matters when you're validating multiple third-party protections or justifying DDoS spend to finance; DORA and NIS2 compliance mapping also saves you the documentation work. Skip this if your organization lacks the internal bandwidth to run self-service testing regularly, since Avydos demands active engagement rather than passive monitoring.
Security teams building internal threat simulation programs on AWS or GCP will get the most from Leonidas because its YAML-based framework lets you define attacker procedures once and automatically generate executable code, detection rules, and documentation simultaneously, cutting your simulation development cycle by weeks. The 593 GitHub stars and active community contributions signal real adoption among cloud-native shops that prioritize repeatability over point-and-click simplicity. Skip this if your org needs a managed SaaS platform with guided scenarios and executive reporting; Leonidas assumes you're engineering-heavy and comfortable maintaining your own TTP library.
Self-service cloud platform for controlled DDoS simulation and resilience testing.
A framework for executing cloud attacker tactics, techniques, and procedures (TTPs) that can generate APIs, Sigma detection rules, and documentation from YAML-based definitions.
