CNAPP for multi-cloud security

1. Wiz — my default choice for multi-cloud

For an organization where AWS + Azure + GCP are all important, I'd put Wiz at the top of the evaluation list.

Its core advantage is the Wiz Security Graph: it correlates cloud assets, vulnerabilities, identities, exposure, permissions and data to identify attack paths rather than presenting thousands of disconnected findings. Wiz also emphasizes agentless discovery and can connect to cloud environments through APIs.www.wiz.io+1

That makes it particularly attractive if your biggest problem is:

"We have enormous amounts of cloud security data, but don't know which risks actually matter."

Watch-out: if deep runtime workload protection is your #1 requirement, make sure you evaluate Wiz's runtime capabilities alongside the alternatives rather than assuming the agentless architecture covers every runtime use case. Wiz now offers Wiz Sensor and describes real-time runtime detection as part of its platform.www.wiz.io+1

2. Palo Alto Networks Prisma Cloud — strongest candidate for maximum security depth

I'd put Prisma Cloud at the top of the bake-off if you're looking for the broadest security lifecycle coverage, particularly:

• Cloud posture
• Workload/runtime protection
• Containers and Kubernetes
• IaC
• CI/CD and application security
• Vulnerability management
• Compliance
• Multicloud/hybrid environments

Palo Alto describes Prisma Cloud as covering infrastructure, workloads and applications throughout the development lifecycle across hybrid and multicloud environments. It supports both agent and agentless approaches for workload protection.www.paloaltonetworks.com

The tradeoff is generally complexity: Prisma Cloud can make more sense when you have a mature security engineering organization that will actually exploit its breadth.

3. Microsoft Defender for Cloud — compelling if Microsoft is already strategic

Don't dismiss Defender simply because you're multi-cloud. Microsoft explicitly positions Defender for Cloud as a CNAPP supporting multicloud/hybrid environments, including AWS and GCP. Its capabilities span CSPM, DevSecOps and workload protection.learn.microsoft.com

It becomes especially compelling if you're already heavily invested in:

• Microsoft Defender XDR
• Microsoft Sentinel
• Azure
• Entra ID
• Microsoft security operations

Microsoft is also integrating Defender for Cloud into the Defender portal, bringing cloud, code and threat protection into the broader Microsoft security ecosystem.learn.microsoft.com

4. Orca Security — worth including in the POC

Orca is particularly interesting if agentless deployment and rapid visibility are priorities. It competes directly with Wiz around agentless cloud discovery and risk correlation.

I'd include it in the evaluation if you want to minimize agents installed throughout your cloud estate.

What I'd do in your situation

Rather than asking vendors for generic CNAPP demos, I'd run a 2–3 week POC with:

Wiz vs. Prisma Cloud vs. Defender for Cloud

and score them against your actual environment.

I'd weight the evaluation roughly:

1. Cross-cloud asset visibility — 15%
2. Attack-path/risk prioritization — 20%
3. Runtime protection — 15%
4. Identity/entitlement risk — 10%
5. Kubernetes/container security — 10%
6. Data security — 10%
7. Code/IaC/CI-CD security — 10%
8. Operational overhead — 5%
9. Reporting/compliance — 5%

The critical test is not how many checks each product finds. Give each vendor the same deliberately messy cloud environment and see which one gets your team from "10,000 findings" to "these 20 things need fixing now."

Bottom line

For a heterogeneous multi-cloud estate, I'd start with Wiz.
For maximum breadth/depth and strong runtime + developer security, put Prisma Cloud head-to-head with it.
If Microsoft is already your security operating system, Defender for Cloud deserves a serious POC.

One caveat: vendor comparisons published online are often marketing-heavy, so I would treat third-party "best CNAPP" rankings as directional rather than authoritative. Current sources also show that there isn't a universal winner; the architectural fit matters substantially.protego.me

If you tell me your AWS/Azure/GCP percentages, Kubernetes usage, approximate cloud workload count, and whether you're already a Palo Alto/Microsoft/CrowdStrike shop, I can narrow this to a specific recommendation and a vendor POC scorecard.
