Rapid7 InsightCloudSec vs Tenable Cloud Security: Side-by-Side Comparison (2026)

Rapid7 InsightCloudSec

Mid-market and enterprise security teams managing multi-cloud infrastructure will get the most from Rapid7 InsightCloudSec because it combines agentless visibility with automated remediation, cutting your mean-time-to-fix on cloud misconfigurations by removing manual triage. The platform covers eight NIST CSF 2.0 functions including continuous monitoring and platform security, with particular strength in CIEM and IaC scanning that most point solutions skip. Skip this if your priority is runtime threat detection over infrastructure posture; InsightCloudSec prioritizes what's exposed and how to fix it, not what's actively exploiting it.

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.
