CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
SMBs and mid-market companies facing frequent DDoS attacks will find BlockDoS's flat-rate unlimited protection model more predictable than per-gigabit vendors, since you pay the same whether you're hit with a 10 Gbps or 500 Gbps assault. The 150+ global PoPs and multi-vendor mitigation strategy give you geographic redundancy and attack absorption capacity without bandwidth overage surprises. Skip this if your organization needs integrated WAF, bot management, or API protection bundled with DDoS mitigation; BlockDoS stays focused on volumetric and protocol attacks only.
Mid-market and enterprise teams defending against sustained volumetric attacks will find DOSarrest valuable for its always-on cloud scrubbing architecture, which absorbs traffic before it reaches your perimeter. The tool aligns to NIST PR.IR by embedding DDoS resilience into your infrastructure layer rather than bolting it on after breach detection fails. Skip this if you need integrated WAF or bot management; DOSarrest focuses on the pipe itself and leaves application-layer threats to other tools.
