Based 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 that need DDoS mitigation without managing their own scrubbing centers should use AT&T Dynamic Defense; you're buying carrier-grade infrastructure and 24/7 managed response, not just software. AT&T's network position means attack traffic gets filtered upstream before it reaches your edge, which matters more than detection speed when you're absorbing volumetric floods. The NIST alignment skews toward Detect and recovery readiness rather than prevention architecture controls, so this works best for teams that accept DDoS as inevitable and want fast mitigation, not those betting on stopping attacks before they land.
Hosting providers and ISPs defending customer web properties at scale should prioritize Blackwall GateKeeper for its L7 DDoS mitigation with behavioral analysis, which catches volumetric and application-layer attacks that signature-only solutions let through. The BGP Flowspec integration and white-label REST API mean you can filter upstream at your network edge and resell protection as a control panel plugin to your own customers. Skip this if you need workload protection or API security beyond the web tier; GateKeeper is purpose-built for perimeter defense, not deep application instrumentation.
