My preference is for the native AWS WAF as we already use it. The rub comes from how the cluster is architected which would mean we’d have an ALB ingress per application - the prohibitive cost is purely the extra ALBs that would be created. Though I literally just heard it’s not going to be as bad as initially forecast so ¯_(ツ)_/¯

My original curiosity was if any of the K8s specific WAFs are any good, for example Prophaze.
