Hi everyone, I've been lurking here for a while trying to learn. Big thanks to all the contributors—this forum has been a lifesider.
My company has been using Prisma Cloud Compute (the container and host security part) for about a year. Our cloud team was happy with it for runtime defense and vulnerability scanning. Recently, our leadership decided we needed a full "cloud-native application protection platform" (CNAPP) and pushed us to upgrade to the full Prisma Cloud suite, which includes everything from Compute to Cloud Security Posture Management (CSPM), IaC scanning, and more.
The problem? The quote came in at more than double what we were paying for just Compute. We've had the full platform for a quarter now, and I'm trying to figure out if the value is really there.
From my (admittedly new) perspective:
- The CSPM alerts are overwhelming. We get hundreds of "critical misconfigurations" across our AWS accounts, but many seem to be for unused services or are flagged as low-risk by our cloud engineers. It's creating a lot of noise.
- The IaC scanning (for Terraform) is cool in theory, but it feels like a separate workflow that our devs haven't really adopted yet.
- We're still mostly using the Compute features we already had.
My question for those who made a similar switch: did you find a way to make the full platform "click"? Was it just a matter of tuning the policies over time, or did you end up using specific features that justified the cost? I'm worried we're paying a huge premium for dashboards and alerts we don't actively use, but maybe we're just not there yet maturity-wise?
Any real-world experiences would be super helpful. Feeling a bit in over my head 😅
I'm Daniel, a DevOps lead at a 350-person fintech company, and we run a couple hundred microservices across AWS ECS and EKS. We evaluated the full Prisma Cloud suite last year after using their Compute module for container scanning.
Core comparison based on my hands-on trial and budget conversations:
1. **Price jump and hidden costs:** Going from Compute-only to the full CNAPP was a 2.2x multiplier for us. The real kicker was the "workload" pricing model for CSPM - we got billed for every cloud resource scanned, including dormant RDS instances and old S3 buckets we forgot to delete.
2. **CSPM noise vs. real signal:** We had the same alert fatigue. Out of 500+ initial critical CSPM findings, our cloud team dismissed over 60% as non-issues for our specific context (like requiring MFA on a test account with no permissions). Tuning it down to a manageable 15-20 actionable alerts per week took two sprints.
3. **IaC scanning adoption gap:** The Terraform scanning is powerful but lives in a separate portal. Our platform engineers liked it, but app developers never logged in. Value only materialized after we forced its checks into the CI pipeline, which added 3-4 minutes to our build times.
4. **Where the full suite truly wins:** The correlation is the killer feature. A single dashboard linking a runtime alert from Compute back to the specific misconfigured IAM role in CSPM and the flawed Terraform code that created it cut our investigation time for serious incidents from hours to under 30 minutes.
My pick: if you have a dedicated cloud security team (even 2 people) to manage the CSPM chaos and enforce pipeline gates for IaC, the full CNAPP is worth it for the investigative workflow. If you're a lean team just trying to secure containers in production, stick with Compute and add a cheaper, focused CSPM tool. To decide, tell us the size of your team managing alerts and if you can mandate IaC scanning in CI/CD.
That point about the IaC scanning adoption gap is so real, and it's the classic story with these platforms. The value isn't in the feature, it's in the user workflow.
We forced the IaC checks into CI/CD too, but we ran into the opposite issue on timing: our platform team spent weeks customizing the rule sets to match our internal policies. Once we did, the build-time scans became a negotiation point, not just a blocker. Devs started asking us to tweak rules for their specific service architecture, which was a good sign of engagement.
It's a huge hidden cost - the platform engineering hours to make it usable often outweigh the license fee. Did you find that customization helped reduce the alert noise for your devs, or was it just a different kind of overhead?
Ah, the classic "we bought the whole security suite and now we're drowning in it" scenario. Let me guess - someone in leadership saw a Gartner quadrant slide and thought coverage equals security.
The noise you're describing with CSPM is the product's actual function. It's designed to generate an auditable list of findings so the vendor can check a compliance box, not to make your cloud team's life better. The value question is backwards: you don't ask if the new alerts are valuable, you ask if the compliance coverage justifies the cost and the fatigue.
And the IaC scanning "separate workflow" problem is a feature, not a bug. It's a different team, a different console, a different policy engine. Did anyone actually map out the process changes before signing that 2x contract? Unlikely.
But what about the edge case?
You're spot on about the "coverage equals security" mindset. I've seen the exact same Gartner slide trigger a panic upgrade at a previous place.
What I'd add is that the "auditable list of findings" often becomes its own product requirement. Once you have a full CNAPP, the security team starts reporting on alert volume and closure rates to leadership, which then gets measured. You end up optimizing for metric reduction, not actual risk reduction. It's a weird loop where the tool dictates the process.
The separate workflow for IaC scanning is the killer, though. Even if you customize the rules, you're now maintaining security logic in two different policy engines - one in your CNAPP and one (probably) in your OPA or terraform-compliance setup. Which one is the source of truth when they conflict? That coordination cost never shows up in the vendor's sales deck.
Latency is the enemy, but consistency is the goal.
That's an interesting perspective on customization leading to engagement rather than just overhead. Our experience with IaC scanning was similar in that the initial time investment was high, but the outcome differed.
We found that while developers did engage with the customized rule sets, it created a decentralized policy management problem. Teams started requesting exceptions and tweaks that, over time, undermined our baseline security posture. The negotiation became a constant drain on the platform team's time.
So in our case, the hidden cost shifted from initial setup to ongoing policy arbitration. Did you establish a governance process to manage those requests, or did the platform team remain the sole gatekeeper?
