Sysdig Secure alternatives for Kubernetes vulnerability scanning

Searches for a Sysdig alternative usually come from teams that want the vulnerability-management half without the per-host enterprise contract, or that do not want a privileged agent on every node for what is, for them, a visibility problem.

What Sysdig Secure does well

Before the list: Sysdig Secure is a good tool for the right team. 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.

  • The most complete runtime story in the category: Falco-based detection, eBPF “in use” vulnerability filtering, and incident response in one agent.
  • Prioritisation uses EPSS and CISA KEV plus runtime context, with base-image fix suggestions and automated PR fixes.
  • Mature enterprise platform with CSPM, CIEM, IaC scanning and compliance packs alongside container security.
  • Large reference customers and a full support organisation.

Sysdig Secure pricing

Sysdig does not publish list prices. Marketplace listings and reported deals put Sysdig Secure in the region of $40–120 per host per month depending on modules, so cost scales with node count and a mid-sized fleet is a five-figure annual contract. StackRadar is priced per cluster, not per node, with all prices on the pricing page.

Sysdig Secure 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 Sysdig Secure is stronger: you need runtime threat detection and response, not just vulnerability tracking. See StackRadar vs Sysdig Secure for the full comparison.

2. 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

3. Aqua Security Platform

Aqua Security is the enterprise container-security platform from the maintainers of Trivy, covering image scanning, Kubernetes security posture, runtime protection and supply-chain controls, sold to enterprises through sales.

Best for: You need runtime protection, admission control and enforcement, not just visibility. Pricing: Quote-only; free Trivy tooling separately. Compare with StackRadar · Aqua Security Platform website

4. Wiz

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.

Best for: You need cloud-wide posture, identity and attack-path analysis, not just Kubernetes vulnerabilities. Pricing: Enterprise; ~$24K/yr per 100 workloads on marketplaces. Compare with StackRadar · Wiz website

Should you switch?

Choose Sysdig Secure if

  • You need runtime threat detection and response, not just vulnerability tracking.
  • Runtime “in use” filtering of vulnerabilities is a requirement.
  • You are consolidating CSPM, CIEM and container security into one enterprise contract.
  • Your security team wants a vendor with a 24/7 support organisation behind it.

Choose StackRadar if

  • You want the vulnerability-tracking half at a price a platform team can approve itself.
  • You do not want a privileged closed-source agent on every node.
  • You want to see and verify the scanner’s code, the advisory source and the scoring formula.
  • You want EU-only data residency with only SBOMs leaving the cluster.

Frequently asked questions

How much does Sysdig Secure cost?

Sysdig does not publish pricing. Reported figures range from roughly $40 to $120 per host per month depending on the modules licensed, which puts a 20-node cluster at about $10,000–29,000 per year. Get a quote from Sysdig for your fleet.

Is StackRadar a Sysdig replacement?

Only for the vulnerability-tracking part. StackRadar does not do runtime threat detection, CSPM or incident response. If those are what you buy Sysdig for, StackRadar is not a substitute; if you want SBOM-based vulnerability tracking across clusters at a flat price, it is.

Does StackRadar do runtime “in use” filtering?

No. StackRadar ranks every finding by CVSS, EPSS and CISA KEV in the open rather than filtering by what an eBPF agent observed loaded in memory.
