Sysdig Secure vs Tenable Cloud Security: Side-by-Side Comparison (2026)

Sysdig Secure

Mid-market and enterprise teams running containerized workloads need Sysdig Secure for its runtime-first approach to threat detection; it combines Falco-powered process-level visibility with cloud context in ways that catch active exploitation attempts that posture scanners alone miss. The Cloud Attack Graph ties runtime alerts to actual entitlements and misconfigurations, which means your alerts come with built-in risk prioritization instead of noise. Skip this if your stack is primarily serverless or you need deep CSPM coverage as your primary control; Sysdig Secure is stronger on the Detect and Continuous Monitoring side of NIST CSF than on the Govern side.

Tenable Cloud Security

Mid-market and enterprise security teams managing multi-cloud infrastructure will get the most from Tenable Cloud Security because it actually connects asset discovery to risk prioritization across hybrid environments, not just listing what you have. The platform covers seven distinct security functions (CSPM, CIEM, CWP, DSPM, IaC scanning, KSPM, and attack path analysis), which means fewer tool switches and less context loss when moving findings between teams. The caveat: if your organization runs primarily on a single cloud provider or doesn't care about entitlement and data classification risks, you're paying for breadth you won't use.
