How do we move to a modern CICD approach

This may also be a general pulse; but here lies the issue

We use EKS, we have Jenkins, we have Ansible, we have Terraform, we have BitBucket; but none of these really form a pipeline and I'm stuck with answering; do we need more (FluxCD/AgroCD/drone.io) etc... or what we have is enough and it's simply about stringing these things together.

Currently, Jenkins really just does mostly app deployment stuff of business app for our devs; but if I wanted to deploy like Fluentd to our clusters or pod security policies, it'll usually require me to manually deploy it.

Really trying to think of a modern CICD approach with security as the forefront, most of our usescases is deploying stuff to kubernetes; but that is not all of our usecase (some scragglers like firewall automation)

Answer

It seems to me you are dealing with an operational environment which has changes made to it _outside_ of the usuall application delivery pipeline. Instead of adding or worrying about tools, can you try to describe what _processes_ you feel are missing?
