Spending the month untangling another client's multi-cloud CSPM mess, so this topic is painfully relevant. Everyone's shouting about "cloud workload protection" but when you're neck-deep in AWS bills, the real question is: does it actually secure things *without* creating a new financial crisis and locking you into a proprietary ecosystem?
Prisma Cloud is the obvious elephant in the room, but "obvious" and "optimal" are rarely the same thing. For AWS-native shops, the calculus in 2026 seems to be:
* **Prisma Cloud (Compute)**: The integrated suite play. You're buying the whole Palo Alto universe.
* The good: Depth of visibility, especially if you're already using their firewalls. The compliance mapping is exhaustive.
* The bad: The cost. It's a second mortgage. And the agent-based approach for hosts/containers can feel... heavy. You start wondering how much of your cloud bill is just monitoring the monitoring.
* **AWS Native (Security Hub + GuardDuty + Inspector)**: The "why pay a middleman?" argument.
* The good: Tighter integration, no egress costs for findings, and it's *their* problem to keep up with new AWS services.
* The bad: You're all-in on AWS. The console sprawl is real. Custom policies can turn into a Sphinx riddle. And let's be honest, the reporting/UI feels like a 2015 internal tool.
* **Wiz**: The new-school contender.
* The good: Agentless, fast deployment, and their graph-based approach cuts through alert noise faster than anything I've seen.
* The bad: It's another SaaS silo. The pricing model is... creative. And for pure AWS, you're paying for a lot of multi-cloud capability you might not need.
My cynical take for 2026: If you're a large enterprise already married to Palo Alto's network security, Prisma Cloud is the path of least resistance (and highest cost). For a lean, AWS-only team trying to maximize security dollars, the native tools, augmented with some smart automation, are hard to beat despite their clunkiness.
What's everyone else seeing? Specifically:
- Any real-world data on alert fatigue comparison between these?
- Has anyone successfully used Terraform/OpenPolicyAgent to make the AWS native stack feel less bolted-together?
- Is the "single pane of glass" worth the 30% premium Prisma commands?

Every cloud has a dark cost.
Your point about the AWS native stack integration is spot on, especially the part about egress costs. That's a real budget killer at scale that often gets overlooked in vendor slides.
But the performance tax of the all-in AWS approach is where it gets messy. Security Hub aggregation latency is non-trivial when you're correlating GuardDuty findings with Inspector scans across thousands of instances. I've measured delays of 90-120 seconds before a consolidated view appears, which is an eternity if you're automating responses. You end up building your own queuing system on top of their queuing system.
And while it's "their problem" to support new services, the rollout lag is consistent. New instance types or database flavors often have a 4-6 week blind spot before the managed rules catch up. That gap forces you to maintain custom configs anyway, negating some of the simplicity promise.

Exactly. The rollout lag for new services is the killer, and it's not a bug, it's a feature of their business model. They get to sell you a "managed" service that's perpetually playing catch up. So you're paying for the privilege of being the beta tester for their rule sets every time your devs use something new.
That 90-second delay for Security Hub is funny. It turns their whole "single pane of glass" into a stained-glass window with a six-month construction delay. You wind up building custom glue logic anyway, which means you're just paying AWS for the raw data feeds and doing the actual work yourself.
So much for simplifying the stack.

You've nailed the hidden cost. "Monitoring the monitoring" isn't a joke, it's a real line item. That Prisma agent overhead can add a surprising 10-15% to your compute bill once you factor in the memory/cpu reservations it needs to run reliably.
For pure AWS shops, I think the native stack's biggest sin is the operational drag. Sure, you avoid egress, but you're now a full-time AWS security product manager, gluing services together and waiting on their roadmap. The "no middleman" argument falls apart when you spend half your week being that middleman.
Any chance your client looked at the newer, more targeted players like Wiz or Orca? Their agentless models change the overhead math, though you do get that egress hit you mentioned.
Keep automating!
