Anyone running Palo Alto Cloud CDR at scale in a multi-cloud environment?

Alright, who else is getting paged because some workload in Azure decided to talk to a random IP in AWS that *wasn't* in the allow list Prisma Cloud swore it had covered? 🙃

We've been running Palo Alto's Cloud CDR (the network security/posture bit) for about 18 months now. Multi-cloud setup: GKE on GCP, a bunch of EC2 + EKS on AWS, and some legacy VMs in Azure. The promise was solid: one pane of glass for all our cloud network security, auto-discovery, and policy enforcement. The reality... is a mixed bag of "oh cool" and "oh come on."

**The Good (what keeps us from ripping it out):**
* The visualization is legit. Seeing actual traffic flows between workloads, across cloud accounts, saved our butts during incident response. No more grepping VPC flow logs in three different consoles.
* The auto-tagging for workloads is decent. Makes policy creation based on environment (prod/dev) or app tier way easier than manual tagging.
* API-driven, which means we can (mostly) treat it as code. Our posture policies are defined in Terraform, which is a win.

**The Gotchas (the reason I'm posting at 3 AM):**
* The "scale" part gets weird. The agent-based model (for runtime defense) adds overhead. We had to tune the hell out of resource requests for their DaemonSet in our big clusters.
* Policy logic can be... surprising. Example: a rule to block egress to the internet from prod. Sounds simple. But their inheritance model from cloud accounts -> VPCs -> workloads bit us when someone spun up a new VPC and the default "learning" mode allowed everything for a week.
* API latency for changes. You push a policy change via their API, and sometimes it takes a solid 5-10 minutes to propagate. In a rapid-scale event, that's an eternity.

Here's a snippet of the Terraform we use for a simple ingress policy. It works, but the state management is fragile—their provider doesn't always detect drift well.

```hcl
resource "prismacloud_policy" "deny_lateral_movement" {
name = "Block cross-namespace ingress in prod"
policy_type = "network"
cloud_type = "aws"
severity = "high"
labels = ["network", "prod", "terraform"]
description = "Prevent prod workloads in different namespaces from communicating."

rule {
name = "Network Rule"
rule_type = "Firewall"
parameters = {
"effect" : "deny",
"from" : "namespace != ${var.namespace}",
"to" : "namespace = ${var.namespace}",
"port" : "any"
}
}
}
```

Anyone else dealing with this? Specifically:
* How do you handle policy updates across 50+ cloud accounts without the console timing out?
* Any success with their CI/CD plugin for policy as code, or did you roll your own?
* False positives on "anomalous" traffic patterns—did you just turn that module off?

Pager duty survivor.
