What our shortlists say about the one we picked.
Best for: Teams needing out-of-path WAF without SSL certificate sharing
Kubernetes environment support is listed as a deployment target, which is relevant for teams running containerized workloads. The ability to deploy across on-premises, public cloud, private cloud, multi-cloud, and Kubernetes under a single management console reduces the operational complexity of managing WAF policies across a modern hybrid architecture. The main caveat is that core features are not extensively documented in public-facing materials, so a proof-of-concept engagement with Radware is advisable before making a purchasing decision.
