How Secuno handles this

Secuno correlates vulnerabilities like CVE-2025-2775 against the real software inventory on every managed device, as each hourly inventory arrives. Rather than a static severity, each match is scored in context: exploit availability, EPSS, the asset's exposure, and business criticality decide where it lands in the queue.

If an affected version is present anywhere across your portfolio, it surfaces automatically with a prioritised remediation path.
