Gatekeeper is a free distributed denial of service mitigation tool. Akamai Prolexic is a commercial distributed denial of service mitigation tool by Akamai. Compare features, ratings, integrations, and community reviews side by side to find the best distributed denial of service mitigation fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Enterprise and mid-market security teams defending distributed infrastructure should pick Akamai Prolexic for its zero-second mitigation SLA backed by 32 global scrubbing centers and 20+ Tbps capacity; you get DDoS containment that actually stops traffic before it reaches your origin. The 24/7/365 SOC paired with custom runbooks means you're not managing this alone across cloud, on-premises, and hybrid deployments. Skip this if your organization needs DDoS detection and response tuning as a learning exercise; Prolexic assumes you want the attack stopped immediately, not investigated afterward.
