I want to use a multi-domain SAN certificate for 5 of my public-facing domains. All of these domains point to the same ingress server (SSL is terminated at the load balancer), but the backend processing for each may be different.
Is SAN is a good choice or should I go with a single domain certificate for each of the domains considering the security?.
If I go with a single domain certificate, does the compromise of one domain affect all other domains since all are terminated to the same ingress server controller?
