CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:

Fastly Bot Management

SMB and mid-market teams protecting web applications from credential stuffing and account takeover will get the most from Fastly Bot Management; its server-side and client-side bot classification engine catches attacks that rule-based filters miss, and the Network Learning Exchange reputation feed means you're blocking IPs flagged across Fastly's customer base. The real-time dashboard gives you visibility into bot behavior patterns without requiring a separate SIEM integration. Skip this if your primary concern is DDoS mitigation at scale; while Fastly includes DDoS protection, dedicated DDoS vendors with stronger volumetric attack capabilities will outperform it on pure throughput defense.

Gatekeeper

Network operators and service providers facing multi-vector DDoS attacks will find Gatekeeper's distributed algorithm approach valuable because it actually scales with your bandwidth requirements instead of hitting throughput walls like centralized scrubbing centers do. The open source model with 1,591 GitHub stars means you're not locked into vendor infrastructure, and deployment across your own edge nodes gives you detection latency measured in milliseconds rather than the round-trip delays of cloud mitigation services. Skip this if your primary concern is stopping Layer 7 application attacks; Gatekeeper prioritizes network-layer volumetric defense, leaving sophisticated HTTP floods to separate WAF tooling.
