StackRadar vs 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.

What Sysdig Secure does well
- 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.
How Sysdig Secure and StackRadar differ
The differences are about how the two are built and sold, not a feature checklist. Each point below is a structural fact you can verify on the vendor's own documentation.
- Sold per host through sales. Reported pricing is in the range of $40–120 per host per month, so a 20-node cluster lands somewhere around $10–29K per year; StackRadar’s top self-serve plan is $199 per month for fifteen clusters.
- A closed agent with elevated privileges runs on every node. StackRadar’s scanner is a single published-source deployment that only reads the Kubernetes API and pulls images.
- Sysdig is a platform purchase — CSPM, runtime, vulnerability management — where StackRadar is one job: SBOM and vulnerability tracking for running workloads.
- Vulnerability data and scoring are the vendor’s; StackRadar matches against the open OSV.dev database and publishes its scoring formula.
Side by side
| Axis | StackRadar | Sysdig Secure |
|---|---|---|
| Where it runs | One Helm chart in the cluster, source published; managed dashboard | eBPF agent on every node; vendor SaaS |
| Kubernetes runtime inventory | Yes — every running image, with its workload, Helm release and ArgoCD application | Yes |
| SBOM | CycloneDX 1.6 per running image (Syft), stored and re-checked as new advisories land | Yes, paired with runtime data |
| Prioritisation | Radar Score — CVSS, EPSS and CISA KEV combined in a published formula | EPSS, KEV and runtime “in use” context |
| History and trends | 30 days (Free), 1 year (Pro), 2 years (Business) | Yes |
| Multi-cluster view | One dashboard across every cluster in the organisation | Yes |
| Scanner source | Published on GitHub; releases signed and version-pinned | Closed (Falco engine is open source) |
| Pricing | Published: Free $0 · Pro $59/mo · Business $199/mo | Quote-only, per host |
| Data residency | EU only; only the SBOM leaves the cluster | Regional SaaS options; US vendor |
Pricing
Sysdig Secure: 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.
StackRadar: Free for one cluster with 30 days of history; Pro at $59 per month for up to five clusters and one year of history; Business at $199 per month for up to fifteen clusters and two years. Every plan scans every image you run. Full details on the pricing page.
Which should you choose?
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.
