Features, pricing, ratings, and pros & cons — compared head-to-head.
Avydos DDoS Threat Simulation is a commercial threat simulation tool by Avydos. Caldera 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 an adversary emulation program on a shoestring budget should start with Caldera; it's the only free framework that lets you automate attack chains against your own infrastructure without vendor lock-in. MITRE's backing means the technique mappings to ATT&CK are authoritative, and you get a real agent-based architecture that scales across hundreds of endpoints. Skip this if you need a polished UI or managed red team operators; Caldera requires security staff who are comfortable with YAML configurations and Python customization to extract value.
