SentriKat vs. Rapid7 InsightVM
Rapid7 InsightVM uses scan engines and the Insight Agent to assess vulnerabilities across your environment with Real Risk Score prioritization. SentriKat replaces heavyweight scanners with lightweight agents and multi-source intelligence — focused on the vulnerabilities that are actually being exploited.
Feature-by-feature comparison
| Feature | SK SentriKat | R7 Rapid7 InsightVM |
|---|---|---|

| Scanner Requirements | No heavy scanner needed (agent-based) | Requires dedicated scan engines |
| Starting Price | Free (Early Access) / €199/mo after | ~$10,000+/yr (per-asset pricing) |
| Vulnerability Focus | CISA KEV (1,484 exploited CVEs) | All 250,000+ CVEs |
| Signal-to-Noise | 99.4% noise reduction | Real Risk Score filtering |
| Intelligence Sources | 6+ feeds (NVD, CVE.org, EUVD, KEV, EPSS, OSV) | Single source |
| Deployment Model | On-premise + Cloud available | Insight Platform (cloud-based) |
| NIS2/DORA Compliance | Native compliance reporting | Limited compliance capabilities |
| ENISA EUVD Integration | Native EU database integration | No EU database support |
| Vendor Backport Detection | Automatic (4 feeds daily) | Manual verification |
| Container Scanning | Included (Docker & Podman) | Separate product |
| CVE Coverage Breadth | Focused (~1,484 KEVs) | 250,000+ CVEs with Real Risk Score |
| Endpoint Agents | Windows, Linux, macOS | Windows, Linux, macOS |

SentriKat vs Rapid7 InsightVM: lightweight agents, focused intelligence
Rapid7 InsightVM is a well-known vulnerability management platform that combines network-based scan engines with the Insight Agent for continuous endpoint assessment. It uses Rapid7's Real Risk Score to prioritize vulnerabilities based on threat intelligence and exploitability. For organizations invested in the Rapid7 Insight platform — which includes InsightIDR for detection and InsightConnect for SOAR — InsightVM fits naturally into a broader security stack.
The architectural difference starts with agents. Rapid7 InsightVM typically requires deploying dedicated scan engines across your network segments, plus the Insight Agent on endpoints. These are substantial software components. SentriKat takes a fundamentally lighter approach: its agents are shell scripts under 5 MB that collect software inventory data and report back. No scan engines, no heavy infrastructure — just lightweight data collection.
Intelligence sourcing is another key differentiator. Rapid7 InsightVM relies primarily on its own vulnerability database. SentriKat aggregates intelligence from 6+ authoritative sources — NVD, CVE.org, ENISA EUVD, CISA KEV, EPSS probability scores, and OSV.dev — with automatic fallback. When the NVD experienced its 2024 slowdown, SentriKat users were unaffected because the system automatically fell back to CVE.org and EUVD. Single-source platforms were degraded.
SentriKat's CISA KEV focus reduces noise by 99.4%. While InsightVM's Real Risk Score helps prioritize the 250,000+ CVEs it tracks, it still surfaces thousands of vulnerabilities for teams to evaluate. SentriKat surfaces only the ~1,484 CVEs confirmed to be actively exploited — every alert is actionable, and teams can focus remediation effort where it matters most.
Cost is dramatically different. Rapid7 InsightVM uses per-asset pricing that typically starts at $10,000+/year and scales with the number of assets in your environment. SentriKat's Cloud Pro plan is €199/month with all features included. For a 100-asset environment, InsightVM could cost 5x or more than SentriKat.
For European organizations, SentriKat offers on-premise deployment, native ENISA EUVD integration, and built-in NIS2/DORA compliance reporting. Rapid7's Insight Platform is cloud-based with limited on-premise options, does not integrate with European vulnerability databases, and offers limited EU-specific compliance capabilities.
