SentriKat vs. enterprise scanners
Enterprise vulnerability scanners track 250,000+ CVEs and charge per module. SentriKat focuses on the ~1,484 that are actually being exploited — with everything included for €4,999/year.

Why teams switch to SentriKat
Enterprise vulnerability scanners like Tenable Nessus, Qualys VMDR, and Rapid7 InsightVM are designed to find every vulnerability — all 250,000+ CVEs. For large security operations centers with dedicated triage teams, this makes sense. But for most organizations, it creates overwhelming noise.
SentriKat takes a different approach. Instead of scanning for everything, it focuses exclusively on confirmed exploited vulnerabilities — the ~1,500 CVEs that are actively used by threat actors in the wild. This is the 0.6% of vulnerabilities that represent real, immediate risk to your infrastructure.
What makes SentriKat unique is automatic vendor patch detection. It queries multiple vendor advisory feeds daily and cross-references them against your software inventory. When a vendor has backported a fix, SentriKat detects it automatically — no manual verification needed. This eliminates the most common source of false positives in vulnerability management.
SentriKat is 100% on-premises. Your vulnerability data, software inventories, and scan results never leave your network. This makes it ideal for regulated industries (NIS2, DORA, FINMA), government agencies, and organizations with strict data residency requirements. Air-gapped deployments are fully supported.
At €4,999/year with everything included — SIEM integration, compliance reporting, container scanning, multi-tenant, SSO — SentriKat costs a fraction of enterprise scanners that charge $10,000+ per module. No hidden fees, no per-asset pricing, no surprises.
