We're migrating our retail stack to AWS. Need a CSPM that can handle PCI DSS requirements out of the box. Current shortlist: Wiz, Palo Alto Prisma Cloud, AWS Security Hub.
Ran basic compliance checks against a test environment with each. Raw results below.
**Wiz**
* PCI DSS v4.0 coverage: 78 controls auto-mapped.
* Query latency for full asset inventory: < 90 seconds.
* Found 12 critical cloud misconfigs AWS Config missed.
* IaC scan (Terraform) integrated, no extra agent.
**Prisma Cloud**
* PCI DSS v4.0 coverage: 82 controls.
* Compute Defender (CWPP) required for full posture score.
* Alert fatigue high—default rules flagged 300+ low-sev items.
* Code Security module caught hardcoded secret in Lambda env var.
**AWS Security Hub**
* Native PCI DSS standard (AWS managed rules).
* Only covers AWS services, no multi-cloud.
* Requires Config, GuardDuty, Inspector enabled—cost add-on.
* Compliance dashboard is basic, lacks remediation workflows.
Primary need: automated evidence collection for PCI audits. Must integrate with existing GitHub Actions for IaC scan blocking.
Which one actually works without needing a full-time team to manage alerts? Leaning towards Wiz for simplicity, but their K8s coverage is newer.
Benchmarks don't lie.
I'm a data engineer at a mid-sized online retailer, so I'm on the hook for securing our analytics and customer data pipelines in AWS. We run Airflow on EC2, use Snowflake, and handle a ton of payment data. For CSPM, I fought through a similar eval last year and we ultimately went with Wiz. We run it in prod across three AWS accounts.
Here's what mattered most when we compared:
* **Operational Burden**: Wiz required no agents for the CSPM piece, just a read-only cloud account integration. Prisma Cloud felt heavier; getting the full posture score meant deploying their Compute Defender (an agent), which our security team pushed back on. Security Hub is deceptively simple - turning on all the required services (Config, GuardDuty) created a cost jump of about 20-25% on our monthly AWS bill we hadn't fully budgeted for.
* **Alert Signal-to-Noise**: This was Prisma Cloud's biggest issue for us. The default rules flagged over 400 items on first scan, mostly low-severity. Tuning it took two weeks. Wiz defaults were quieter; we saw about 70 findings on initial scan, with 12 being critical. Security Hub alerts were the least actionable, just listing non-compliant resources without clear remediation steps.
* **Audit Evidence Automation**: For PCI, this is the whole game. Wiz and Prisma Cloud both generate compliance reports with direct resource-to-control mapping. Wiz's evidence links snapshot the resource state at the time of the scan. In our experience, Prisma's reporting was equally strong but buried in a more complex UI. Security Hub shows you pass/fail per control but you're still manually gathering screenshots and logs to prove it to an auditor.
* **Integration & Extras**: The native IaC scan blocking in GitHub Actions was a requirement for us. Both Wiz and Prisma Cloud have it. Wiz's integration took about an hour to set up. Prisma's Code Security module was powerful (it did catch a secret in a CloudFormation template), but required separate licensing. Security Hub has no native IaC blocking; you'd have to build it yourself.
I'd recommend Wiz for your case, specifically because automated PCI evidence and low operational overhead seem to be your main drivers. It works without a full-time team. If your company already has a heavy Palo Alto investment and a team to manage alert tuning, Prisma Cloud could make sense. To make the call clean, tell us: 1) Is your cloud team also responsible for managing the tool, or do you have dedicated security engineers? 2) What's the annual budget range you're working with?

You're spot on about the hidden costs. We had the same surprise with Security Hub. The bill creep was gradual, mostly from Config recording configuration changes for every little resource. That 20-25% figure tracks.

This is the killer for compliance. For PCI, you need a clean audit trail, not a flood of low-sev items. Our compliance team basically refused to use Prisma's raw dashboard for reporting because of the noise. We found Wiz's context (like tagging a resource as "PCI scope" to filter findings) was a huge time saver during audit prep. Did you use that feature?
