"Cloud security" is one label for at least five jobs: watching cloud posture (CSPM), protecting workloads (CWPP), managing entitlements (CIEM), scanning the images and infrastructure code you deploy, and detecting threats at runtime. The convergence of the first four into the CNAPP category has made shopping easier in theory and more confusing in practice, because every vendor now claims the whole spectrum.
This guide compares five platforms teams actually rely on and is deliberately clear about which layer each one owns. It also draws an honest line around where a supply-chain security tool contributes and where it does not.
How to evaluate cloud security tooling
The questions that separate these platforms in real evaluations:
- Agentless versus agent. Agentless scanning via cloud APIs and snapshots deploys fast and covers broadly. Agents give deeper runtime visibility. Most serious programs end up using both.
- Multi-cloud reality. If you run more than one cloud, native single-cloud tools leave blind spots. Weigh coverage parity across AWS, Azure, and GCP.
- Posture plus context. A list of misconfigurations is noise. What matters is a tool that connects a misconfig to an exposed asset with a real attack path.
- Workload and container depth. Image scanning, admission control, and runtime detection for Kubernetes.
- Shift-left coverage. Whether it also scans infrastructure-as-code and images before they reach the cloud, closing the loop with your pipeline.
- Cost and data model. Consumption-based pricing can be unpredictable; understand what drives the bill.
The tools worth comparing
Wiz set the pace for agentless CNAPP. Its graph-based attack-path analysis connects vulnerabilities, misconfigurations, and exposure into a prioritized picture, and it deploys quickly across clouds. It is a strong, popular choice; the honest caveats are enterprise pricing and that agentless snapshots trade some runtime immediacy for breadth.
Prisma Cloud (Palo Alto Networks) is the broad, deep option covering CSPM, CWPP, CIEM, and code security in one suite. Breadth is the selling point and the drawback — it is powerful but complex to configure and operate, and it is priced for organizations that will use most of it.
Microsoft Defender for Cloud is the pragmatic default for Azure-centric estates, with multi-cloud coverage improving and tight integration into the Microsoft security ecosystem and Sentinel. If your organization is already a Microsoft shop, the integration and commercial bundling are compelling. Coverage outside Azure is capable but generally strongest at home.
Orca Security popularized agentless, snapshot-based scanning ("SideScanning") and delivers broad visibility without deploying agents. It competes closely with Wiz on the agentless model. As with any agentless approach, point-in-time snapshots mean runtime detection is not as immediate as an agent would provide.
Sysdig comes from the runtime and container observability world, built on open-source Falco. Its strength is real-time detection and response for Kubernetes workloads and deep runtime insight. It is less a broad CSPM and more a workload-runtime specialist, so many teams pair it with an agentless posture tool.
Comparison at a glance
| Tool | Center of gravity | Standout strength | Watch-outs |
|---|---|---|---|
| Wiz | Agentless CNAPP | Attack-path graph, fast rollout | Enterprise pricing |
| Prisma Cloud | Full-spectrum CNAPP | Breadth and depth | Complexity, cost |
| Defender for Cloud | Azure-first CNAPP | Microsoft ecosystem fit | Strongest inside Azure |
| Orca Security | Agentless scanning | Broad visibility, no agents | Snapshot-based runtime |
| Sysdig | Runtime / containers | Real-time K8s detection | Not a broad CSPM |
Where Safeguard fits (and the honest limits)
Safeguard is not a CNAPP and does not replace any tool above. It does not monitor cloud posture, manage entitlements, or provide runtime threat detection in your production accounts. If those are your needs, choose from the table.
Where Safeguard contributes is the shift-left slice of cloud security — the software and configuration you deploy before it becomes cloud posture. Its IaC scanning catches misconfigured Terraform, CloudFormation, and Kubernetes manifests at the pull request, and container image scanning finds vulnerable and outdated layers before images ship to a registry. Combined with dependency analysis, that closes a gap CNAPPs see only after the fact: a fix at build time never becomes a misconfiguration alert in production. The practical pattern is Safeguard in the pipeline and a CNAPP in the cloud — they cover different halves of the same problem. The comparison hub is the place to see exactly where that boundary sits.
How to choose
If you need one platform to see across a multi-cloud estate and rank real attack paths, evaluate Wiz and Orca head to head on your own accounts. If you want maximum breadth in a single suite and can staff the complexity, Prisma Cloud is the deepest. If you are Azure-first, Defender for Cloud is likely already the cost-effective answer. If your risk is concentrated in Kubernetes runtime, Sysdig is the specialist.
Then decide whether to also close the build-time loop. A CNAPP tells you what is wrong in the cloud; shift-left scanning stops a chunk of it from getting there. Most mature programs run both rather than choosing.
Frequently Asked Questions
Is a CNAPP enough on its own for cloud security?
For posture, workload, and identity risk in running cloud environments, a strong CNAPP covers most needs. What it does not do well is stop issues at build time — vulnerable images and misconfigured IaC that a pipeline scan would catch before deployment. Pairing runtime posture with shift-left scanning is the more complete approach.
Agentless or agent-based — which should I pick?
Agentless deploys fast and gives broad coverage, which is why it dominates initial rollouts. Agents provide deeper, real-time runtime visibility. They are complementary rather than competing, and many organizations use agentless for breadth and targeted agents for critical workloads.
Does shift-left scanning overlap with CNAPP code security?
There is some overlap — several CNAPPs now scan IaC and images. The difference is workflow depth: a supply-chain tool typically lives in the pull request with reachability-based prioritization and automated fixes, while CNAPP code security is one feature among many. Evaluate the depth you need in the pipeline specifically.
How do I test build-time cloud security coverage?
Connect a repository that contains your infrastructure code and container definitions and see what a scan surfaces before anything reaches the cloud. You can start free at app.safeguard.sh/register, and the IaC and container scanning documentation is at docs.safeguard.sh.
