Highlights

An overview of the most impactful changes in this release.

Smart Polling

Smart Polling now autonomously chooses the sensor to engage.

The WMI Smart Polling strategy now supports NTLMv2 authentication.

Smart Polling now takes precedence over the passive detection when providing a device identifier (ID), improving its asset merging capabilities.

Introduced the Smart Polling strategy Belden/Hirschmann Rail Data Diode HTTP(S).

Introduced the Discovery strategy IKEA Dirigera mDNS.

Automatic CPE record cleanup

You can now configure Nozomi Networks Operating System (N2OS) to automatically remove stale Common Platform Enumeration (CPE) records. Software version changes and asset modifications can accumulate orphaned CPE entries over time, consuming storage and skewing vulnerability match results.

A background garbage collector removes stale records without requiring manual intervention.
