    Key Features

    • Command Validation Tool (introduced February 2023): Enables discovery administrators to troubleshoot credential-related discovery issues by auto-fetching commands from the pattern code base. It supports multiple operation types (Shell, WMI, SNMP queries, HTTP GET) and flexible MID Server selection methods.
    • Discovery CLI (introduced November 2023, removed May 2025): Added a CLI command suite dedicated to discovery tasks, simplifying and speeding up discovery workflows. Although removed later, core functions remain accessible via the GUI.
    • Access Control Enhancements (December 2025 and June 2026): Strengthened platform security through stricter client-side protections and refined access controls, including introducing a pdeviewer role with read-only access to all Pattern Designer Enhancements data, and predefined query access controls for all related tables.
    • Improved Command Detection and Validation: Enhancements to command extraction from nested libraries and eval script blocks, improved OS class detection considering shared library inheritance, and ability to prioritize command validation tasks or skip failover commands.
    • Support for Temporary Variables in Pattern Commands (August 2023): Added listing and execution framework support for pattern commands using temporary variables.
    • Multilanguage Support and Bug Fixes: Continuous fixes addressing CLI authorization, command execution issues on Windows, and user feedback improvements for job submissions.
