Gatekeeper vs IMS Networks Transit IP & DDoS Protection: Side-by-Side Comparison (2026)

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.

IMS Networks Transit IP & DDoS Protection

Mid-market and enterprise organizations in Europe needing DDoS mitigation without outsourcing detection should choose IMS Networks Transit IP & DDoS Protection for its owned-and-operated French network backbone and in-house 24/7 monitoring that eliminates vendor subcontracting risk. The 99.95% SLA with guaranteed symmetric bandwidth up to 10 Gbps and no single point of failure directly supports NIST PR.IR infrastructure resilience requirements. Skip this if you need global scrubbing presence or rapid scaling across multiple continents; IMS Networks' strength is regional density and hands-on control, not worldwide reach.
