Continuous automated DDoS resilience testing with 13 passive intelligence sources vs. on-demand DDoS simulation testing.
About Avydos (zeroBS)
Avydos, also known as zeroBS, is a DDoS testing service offering on-demand DDoS simulation for organizations wanting to validate their protection. Their service allows customers to test specific targets against simulated DDoS traffic. Avydos positions itself as an accessible DDoS testing option with a simpler engagement model than traditional enterprise DDoS testing firms.
Avydos focuses on the simulation side of DDoS testing. Like most testing services in this category, their starting point is the customer-defined target - they do not include passive reconnaissance to discover the attack surface before testing.

Where Avydos Excels
Accessible Entry Point
Avydos positions itself as an accessible DDoS testing option. For organizations that want a simple, on-demand test without the complexity of a full recon-to-hardening platform, the narrower scope can be appropriate for specific one-off validations.
On-Demand Flexibility
The on-demand model means you can run a test when you need one without scheduling an enterprise engagement. For quick validation checks before or after infrastructure changes, that immediacy has value.
DDactic Is the Right Choice If...
- You want to map your attack surface first, before deciding what to test
- You need to know whether your CDN is actually protecting your origin
- You want continuous testing as your infrastructure changes, not just one-off runs
- You need L7 application-layer coverage and realistic bot behavior simulation
- You want vendor-specific hardening commands, not just pass/fail results
- Your compliance requirements demand documented evidence of periodic resilience testing
