SentriKat vs. Rapid7 InsightVM

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 cross-checks six independent public databases, one of them European, with automatic fallback. When the largest of them slowed its enrichment through 2024, a design like SentriKat's falls back to the others for records that one has not yet enriched: an architectural advantage a single-source platform doesn't have.

SentriKat's exploited-first focus leaves under one percent of the list. 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 ~1,500 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 €249/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 the European vulnerability database 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.

Who should choose Rapid7. Rapid7 covers credentialed network scanning and web applications, and InsightVM's Remediation Projects track the fix through to done with SLAs, which is more than a ticket per finding. If you have a security team with the hours to work a large finding list, that breadth is worth paying for. We are a specialist, not a suite, and a comparison that pretended otherwise would not survive your first technical call.

Who should choose SentriKat. An organisation in scope for NIS2 or DORA, without a security team, that needs to know which of its exposures are actually being exploited, which are already closed by a vendor patch, and needs the evidence in a report an auditor accepts.
