Wiz alternatives for Kubernetes vulnerability scanning

Searches for a Wiz alternative come from two directions: teams that are far too small for a six-figure CNAPP contract, and enterprises reconsidering vendor alignment after the Google acquisition. Both want the Kubernetes vulnerability piece without the platform.

What Wiz does well

Before the list: Wiz is a good tool for the right team. Wiz is the category-defining agentless cloud security platform — a security graph that correlates vulnerabilities with exposure, identities and attack paths across cloud accounts and Kubernetes — acquired by Google in 2026.

  • The security graph: vulnerabilities in context of network exposure, identity and attack paths, across every cloud resource, not just containers.
  • Agentless deployment through cloud-provider APIs, with an optional runtime sensor.
  • SBOM inventory, IaC and Helm scanning, admission control, and EPSS/KEV-aware policies.
  • The broadest feature set and the largest enterprise install base in the category.

Wiz pricing

Wiz does not publish list prices. AWS Marketplace listings anchor around $24,000 per year per 100 workloads for the Essential tier and about $38,000 for Advanced; reported median contracts are around $159,000 per year. StackRadar’s Business plan is $199 per month.

Wiz alternatives

1. StackRadar (that's us)

StackRadar keeps a CycloneDX SBOM for every image running in your Kubernetes clusters and re-checks it against OSV.dev advisories as they land — no rescan. Findings are ranked by the Radar Score, which combines CVSS, EPSS and the CISA KEV catalogue in a published formula, and every finding carries its workload, Helm release and ArgoCD application. One dashboard covers every cluster, with 30 days to two years of history by plan. The scanner installs as one Helm chart, its source is published, releases are signed, and data stays in the EU. Free for one cluster; Pro $59 per month; Business $199 per month.

Where Wiz is stronger: you need cloud-wide posture, identity and attack-path analysis, not just Kubernetes vulnerabilities. See StackRadar vs Wiz for the full comparison.

2. Sysdig Secure

Sysdig Secure is an enterprise cloud-native application protection platform built on Falco, with an eBPF agent per node, runtime threat detection, and vulnerability management that pairs SBOMs with runtime “in use” data.

Best for: You need runtime threat detection and response, not just vulnerability tracking. Pricing: Quote-only; reported ~$40–120 per host per month. Compare with StackRadar · Sysdig Secure website

3. Microsoft Defender for Containers

Microsoft Defender for Containers is the container-security plan in Defender for Cloud: agentless vulnerability assessment of AKS, EKS, GKE and Arc-connected clusters, registry scanning and an optional runtime sensor, priced per vCore.

Best for: You are an Azure-centric organisation already in Defender for Cloud and Sentinel. Pricing: ~$7 per vCore per month, published. Compare with StackRadar · Microsoft Defender for Containers website

4. Kubescape / ARMO Platform

Kubescape is a CNCF-incubating open-source Kubernetes security scanner; ARMO Platform is the commercial SaaS built on it, adding vulnerability management, eBPF runtime relevancy and, more recently, cloud detection and response.

Best for: You want misconfiguration, compliance and RBAC scanning in the same tool as vulnerabilities. Pricing: Quote-only (was ~$59/node/mo; free ≤10 nodes). Compare with StackRadar · Kubescape website

Should you switch?

Choose Wiz if

  • You need cloud-wide posture, identity and attack-path analysis, not just Kubernetes vulnerabilities.
  • Agentless coverage across many cloud accounts is the priority.
  • You are an enterprise consolidating security tooling into one CNAPP contract.

Choose StackRadar if

  • You want Kubernetes SBOM and vulnerability tracking at a price a team can approve.
  • Your clusters are on-prem, edge or bare metal where agentless cloud scanning does not reach.
  • You want EU-only data residency and an auditable scanner.

Frequently asked questions

How much does Wiz cost?

Wiz is quote-based. Public marketplace listings start around $24,000 per year per 100 workloads, and reported median contracts are in the six figures. It is an enterprise purchase.

Is StackRadar a Wiz alternative?

For Kubernetes SBOM and vulnerability tracking, yes. For cloud-wide posture, identity and attack-path analysis, no — StackRadar does one job and does not try to be a CNAPP.
