To choose a cloud security platform, first decide whether you need runtime sensors, agentless scanning or both. Then compare how well each option prioritizes real, exploitable risk across posture, workloads, identities, data and AI, and what it costs to run at your scale. Most vendors now sell a CNAPP that covers the same acronyms, so the label tells you little. What separates platforms is the evidence behind each finding, which is either a configuration snapshot or live runtime telemetry. That difference decides how much noise reaches your team. This guide, updated in October 2026, sets out the 12 criteria we used and compares 10 options on architecture, prioritization, deployment and pricing. It closes with recommendations by team profile and operating model.
Key takeaways
- ✓Every major vendor now markets a CNAPP, so buyers should compare architecture, prioritization logic and pricing mechanics rather than feature checklists.
- ✓Agentless scanning gives fast, broad visibility, while eBPF runtime sensors show which vulnerabilities are loaded, which identities are used and which threats are unfolding.
- ✓CVE prioritization should combine reachability, packages actually loaded, internet exposure and exploitability rather than relying on CVSS severity alone.
- ✓Cloud security pricing models range from resource units and workload counts to credit systems tied to modules, and these models drive most hidden costs.
- ✓No vendor sensor runs on AWS Fargate or other node-less environments, so serverless-heavy teams still need API-based coverage for those workloads.
Cloud security platform categories and what changed in 2026
Most cloud security platforms are now CNAPPs that bundle several categories that used to be sold separately. Each category answers a different security question. CSO Online describes CNAPPs as a unified and tightly integrated set of security and compliance capabilities. Each component is most useful where it shows real exposure, and each has clear limits.
| Category | What it does | What it does not do |
|---|---|---|
| CSPM | Finds misconfigurations and compliance drift in cloud accounts | Show what is running inside workloads |
| CWPP | Protects VMs, containers and serverless at runtime | Govern account-level configuration |
| CIEM | Maps effective permissions and flags excess or unused access | Detect live credential abuse without telemetry |
| CDR | Detects and responds to active cloud threats | Prevent misconfigurations before deployment |
| KSPM | Audits Kubernetes cluster configuration and policy | Inspect process behavior inside pods |
| DSPM | Discovers and classifies sensitive data and its exposure | Block exfiltration on its own |
| AI workload security (AI-SPM, AI-DR) | Inventories models and pipelines and detects AI-specific misuse | Replace general workload protection |
For a broader map beyond CNAPP, see these types of cloud security tools. Five shifts now shape buying decisions:
- Runtime-powered prioritization: vendors filter out CVEs in packages that sit in an image but never load or cannot be reached.
- Identity-first attacks: stolen tokens and over-permissioned roles are a primary entry point, so CIEM needs usage data and toxic-combination analysis.
- Attack path analysis: graph models link exposure, identity, vulnerability and data sensitivity into chains an attacker could follow.
- Code-to-cloud correlation: leading platforms trace a runtime finding back to the repository, commit or IaC line that introduced it.
- AI workload security: models, inference services and training pipelines now sit inside the platform’s scope.
How we evaluated these platforms
We evaluated each platform against 12 criteria chosen to predict how a tool behaves in production. Length of feature list was not one of them. We assessed four platforms in depth (Upwind, Wiz, Orca Security and Palo Alto Networks Cortex Cloud) using documented architecture, detection, prioritization, coverage and pricing data, plus Gartner Peer Insights reviews. The other six come from widely cited shortlists. Our verified data on them is narrower, so we flag what to validate in a proof of value (PoV).
- ✓Runtime detection: kernel-level telemetry (syscalls, process trees, network flows) versus log-only detection.
- ✓Agent coverage: which hosts, containers and serverless targets a sensor supports, and where it cannot run.
- ✓Kubernetes depth: EKS, AKS, GKE and OKE support, Windows and ARM nodes, and KSPM.
- ✓Multi-cloud support: parity across AWS, Azure and Google Cloud.
- ✓Identity context: effective permissions, unused rights and toxic combinations.
- ✓Risk prioritization: reachability, loaded packages, internet exposure and exploitability (for example, CISA KEV listings).
- ✓Remediation workflows: containment actions, fix generation and ticketing integration.
- ✓DSPM and CIEM: native or bolt-on.
- ✓Shift-left: IaC scanning, CI/CD gates, SBOM and runtime-to-code tracing.
- ✓Pricing model: billing unit and premium modules.
- ✓Deployment complexity: time to first useful finding, as reported by reviewers.
- ✓Evidence: Gartner Peer Insights ratings and recurring reviewer patterns.

Upwind
Upwind is a runtime-first CNAPP that combines agentless discovery with lightweight eBPF sensors. Regional, read-only scanners and cloud API metadata map the environment. Sensors on VMs, containers and serverless then observe in-memory execution, system calls, API activity and network flows at the kernel level. It covers CSPM, CWPP, CIEM, CDR, vulnerability management, KSPM, API security, DSPM and AI workloads (AI-SPM and AI-DR).
- ✓Correlates runtime signals with IAM actions and cloud configuration into Threat Stories, each with a timeline, root-cause analysis and response steps.
- ✓Contains threats through Microsoft Sentinel playbooks that isolate containers, terminate processes and quarantine nodes.
- ✓Flags over-permissioned roles, unused permissions and toxic combinations, with least-privilege policy recommendations.
- ✓Covers code-to-cloud with IaC scanning, CI/CD integration, SBOM and tracing of runtime findings to the line of code.
- ✓Supports EKS, GKE, AKS and OKE, with Linux and Windows Server containers on x86 and ARM.
Deployment: one reviewer reported full installation, “ranging from EKS sensors to cloud connection to CICD taking just a few hours.” Rating: 4.8/5 from 88 reviews on Gartner Peer Insights as of October 2026.
Wiz
Wiz is an agentless-first CNAPP covering CSPM, CWPP, CIEM, CDR, vulnerability management, Kubernetes, API security, DSPM and AI security, with an optional runtime sensor. Its graph links exposure, identities and data into attack paths.
- ✓CIEM computes effective permissions, accounting for SCPs, RCPs, permission boundaries and ACLs.
- ✓IaC scanning covers Terraform, Kubernetes, CloudFormation and ARM, with SBOM export in SPDX and CycloneDX.
- ✓Reviewers report full multi-cloud visibility in under 24 hours, and one replaced five or six tools.

Side-by-side comparison: architecture, pricing and tradeoffs
The biggest tradeoff between platforms is architecture. Agentless-only tools see everything quickly but only at points in time, while sensor-based tools see live behavior on the hosts they cover.
| Platform | Architecture | Runtime detection | CVE prioritization signals | Pricing model |
|---|---|---|---|---|
| Upwind | Agentless discovery + eBPF sensors | Kernel-level, correlated with IAM | Reachable, loaded, exposed, exploitable | Resource units per month; AWS Marketplace |
| Wiz | Agentless-first + optional sensor | Via optional sensor | Reachable, loaded, exposed, exploitable | Quote-based, per workload count |
| Orca Security | Agentless SideScanning | Secondary to discovery | Reachable, loaded, exposed, CISA KEV | Custom private offers on AWS and Azure Marketplaces |
| Cortex Cloud | Runtime sensors + log ingestion | eBPF signals plus cloud logs | Reachable, loaded, exposed, exploitable | Credits by resources, accounts, workload types and modules; AWS Marketplace |
| Defender for Cloud | CSPM + CWPP, Azure-native | Threat detection | Validate in PoV | Confirm with vendor |
| Falcon Cloud Security | Extends the Falcon platform | Real-time workload detection | Validate in PoV | Confirm with vendor |
| SentinelOne Singularity | CNAPP (CSPM + CWPP) | AI-driven detection | Validate in PoV | Confirm with vendor |
| Trend Vision One | Unified lifecycle suite | Detection and response | Validate in PoV | Confirm with vendor |
| Check Point CloudGuard | Posture + threat prevention | Threat prevention | Validate in PoV | Confirm with vendor |
| Tenable Cloud Security | Vulnerability-led | Continuous threat monitoring | Validate in PoV | Confirm with vendor |
Why architecture changes detection fidelity
Snapshot scanning reads disk images on a schedule. It can tell you a library is installed, but not whether it is loaded into memory, and it misses a reverse shell that lives for 40 seconds between scans. eBPF sensors hook kernel events, so they record the process, syscall and network connection as they happen. API-only tools also inherit cloud log latency. Every vendor shares one limit. Sensors cannot run where the provider hides the node, such as AWS Fargate, Lambda, ACI virtual nodes and OKE virtual nodes, so those workloads fall back to API and log coverage.
For example, an image scan might report 4,000 CVEs across 250 container images. If runtime data shows that only 300 of the vulnerable packages ever load, and 40 of those sit on internet-facing services, the fix queue drops from 4,000 to 40. Ask each vendor to run this filter on your own clusters during the PoV.
Hidden cost drivers
- Billing unit: per-workload or per-resource pricing grows with autoscaling, so model peak node and container counts, not averages.
- Premium modules: credit systems can charge separately for DSPM, AI security or CDR.
- SIEM ingestion: forwarding raw findings to Splunk or Sentinel adds ingest cost, so prioritized alerts cost less downstream.
- Tuning labor: reviewers of complex platforms report weeks of alert tuning, which becomes a staffing cost.
How to choose based on your environment and team
The right platform depends on team size, cloud mix and how much of your risk lives in running workloads rather than configuration.
| Profile | Prioritize | Shortlist pattern |
|---|---|---|
| Startup | Fast setup, low tuning, one SKU | Runtime-first or agentless CNAPP |
| Mid-market | Consolidation, noise reduction, CI/CD gates | Upwind, Wiz, Orca |
| Enterprise | Scale, SIEM/SOAR integration, CDR depth | Upwind, Wiz, Cortex Cloud |
| Highly regulated | Framework coverage, evidence, audit trails | Upwind, Cortex Cloud; add dedicated CSPM tools if needed |
| Kubernetes-heavy | Sensor support for EKS, AKS, GKE and OKE, plus KSPM | Runtime-first sensors |
| Multi-cloud | AWS, Azure and Google Cloud parity | Independent CNAPP over hyperscaler-native tools |
Native services such as AWS GuardDuty, Inspector, Security Hub and Google Security Command Center are mostly provider-specific. An independent platform correlates findings across clouds instead of leaving that work to analysts. Run the evaluation in this order:
- Inventory clusters, node types and serverless share, so you know where sensors can and cannot run.
- Pick two or three vendors and run a 30-day PoV on production accounts, not a demo tenant.
- Measure time to first critical finding and the ratio of actionable to total alerts.
- Test one containment action end to end through your SIEM, SOAR and ticketing tools (Jira, ServiceNow).
- Price at peak scale with every module you will need in year two.
Where Upwind fits in a runtime-first security program
Upwind fits teams that want runtime evidence to drive every workflow, from the CVE backlog to incident response. Its Agentic Pack AI agents investigate threats, validate exposure and generate fixes, and they base each output on what is actually running instead of static posture data. Teams operating mostly on Google Cloud should validate GCP coverage depth during the PoV, as a few Gartner Peer Insights reviewers flagged it as still developing.
- ✓Platform engineers work a fix queue limited to loaded, reachable, exposed packages, with fixes generated by the agents.
- ✓SOC leads start investigations from agent-validated findings instead of raw alerts.
- ✓Architects see which identities and permissions are actually used across AWS, Azure and Google Cloud.
- ✓CISOs replace separate CSPM, CWPP, CIEM and DSPM tools with one sensor and one contract.
A buyer’s framework for choosing a cloud security platform
Match the platform type to your security operating model, then test vendor claims on your own workloads.
- Detection-led SOC with Kubernetes at the core: choose a runtime-first CNAPP with eBPF sensors and CDR.
- Posture-led team with a broad, mixed estate: start with an agentless-first CNAPP, then add runtime coverage for production clusters.
- Single-vendor enterprise: extend your incumbent’s suite (Palo Alto, Microsoft, CrowdStrike) if integration matters more than prioritization depth.
- Vulnerability-led program: insist on reachability and loaded-package filtering before signing.
Whichever path you take, judge a cloud security platform by the share of its findings your team can act on within a day. The number of acronyms on its datasheet tells you little.
FAQ
What matters more in 2026: agentless scanning or runtime sensors?
Both matter, but they answer different questions. Agentless scanning gives fast, broad visibility across cloud accounts and workloads, while runtime sensors such as eBPF show live behavior like loaded packages, process activity, identity usage and active threats. The guide recommends deciding first whether you need agentless coverage, runtime coverage or a combination of both.
Why is comparing CNAPP feature checklists no longer enough?
Because most major vendors now market a CNAPP with similar acronyms and module names. According to the article, the real differences are architecture, prioritization logic, deployment complexity and pricing mechanics, especially whether findings are backed by static snapshots or live runtime telemetry.
How should a cloud security platform prioritize CVEs?
The article says CVE prioritization should go beyond CVSS severity and combine signals such as reachability, whether the vulnerable package is actually loaded, internet exposure and exploitability, including sources like CISA KEV. This helps teams focus on the smaller set of issues that are truly actionable.
Can runtime sensors cover Fargate and other node-less serverless environments?
No. The article notes that no vendor sensor runs on environments where the cloud provider hides the node, including AWS Fargate, Lambda, ACI virtual nodes and OKE virtual nodes. In those cases, teams still need API-based and log-based coverage.
What should teams test during a cloud security platform proof of value?
The guide recommends running a 30-day PoV on production accounts, measuring time to first critical finding, checking the ratio of actionable to total alerts, validating one containment workflow through SIEM, SOAR and ticketing tools, and pricing the platform at peak scale with the modules you expect to need in year two.
