What's New

The following features have been implemented or improved in the latest version of WhatsUp Gold:

Master Secret Key

This version of WhatsUp Gold introduces a new encryption mechanism based on a Master Secret Key. The Master Secret Key is generated during installation or upgrade to this version of WhatsUp Gold. Please note, this key is unique to each WhatsUp Gold server. Additionally, a dedicated application is installed with WhatsUp Gold which allows you to manage your Master Secret Key when moving your WhatsUp Gold instance from one server to another. Important considerations:

  • Secure storage. The Master Secret Key must be stored in a safe location separate from the WhatsUp Gold server.
  • Server migration. The Master Secret Key is required to successfully migrate the WhatsUp Gold database from one server to another.
  • Loss. The Master Secret Key is required for database migration and post-recovery access. Loss of this key may prevent recovery of encrypted data.

This enhancement follows modern security best practices and aligns with evolving expectations in today’s security conscious environment. Implementation of the Master Secret Key ensures stronger protection for sensitive data and helps safeguard your monitoring environment against unauthorized access.

Certificate Discovery and Reporting

WhatsUp Gold can now discover certificates on your network and also introduces the ability to report on that data. First, Discovery scans specified IP addresses and ports to identify SSL/TLS certificates and gather rich certificate metadata, including subject, issuer, serial number, timestamps, effective/expiration dates, and whether a certificate is self-signed. This information is presented using new, dedicated inventory and dashboard reports. Beyond capturing certificate attributes, WhatsUp Gold also identifies every way a certificate can be reached, e.g., IP address, DNS hostname, or multiple URLs on the same port. This ensures full visibility into certificate exposures across your environment.

Scan Device Card

Much like the device information cards accessible through the Discovered Network and My Network views, the Scan Results report allows access to a new device details dialog specific to a selected device's discovery. Click on any line item in the Scan Results report to launch the card displaying these key device details gathered during Discovery.

Rescan/Refresh/Reset Improvements

Enhancements have been made to the device rescan, refresh, and reset device and device group management menu options. These changes were implemented for clarity for the user as well as to better align with what WhatsUp Gold is actually doing when any of these options are selected. Please note, no actual functionality has been modified or removed; these enhancements apply to new and updated term usage and associated descriptions within the user interface and accompanying user documentation. Applicable changes are as follows:

  • Basic Rescan replaces the Refresh Device Details option present in previous versions of WhatsUp Gold. Selecting this option performs a standard refresh of the device using current Discovery results. Performing a basic refresh adds new roles and/or subroles if the device matches specified scan criteria and automatically applies monitors and attributes associated with newly-detected roles. However, any existing roles and/or monitors remain unchanged if they no longer match scan criteria.
  • Advanced Rescan replaces the Include user-defined roles control present in previous versions of WhatsUp Gold. Selecting this option is similar to performing a basic refresh, but it also updates monitors based on the device's assigned roles and subroles. Performing an advanced refresh can apply monitors and attributes to a device even if it does not match current scan criteria.

  • Update Inventory Data replaces the Remove Stale Data control present in previous versions of WhatsUp Gold. Selecting this option removes and rescans inventory data for a selected time period and applies the most recent device data available. Updating inventory data can improve role calculation, map information, reporting, and other related areas in WhatsUp Gold.

  • Reset/Replace Device is a new dialog which can be used in two specific scenarios:

    • Select Replace Device if you intend to replace the selected device with the same or similar device and intend to keep the same IP address. Replacing a device removes and re-evaluates device data such as its display name, SNMP OID, operating system, brand, role, subrole, etc. It can also make changes to role-based attributes, custom IP addresses, inventory data, and MAC address.

    • Select Reset Device if you intend to completely reset the device in WhatsUp Gold. Resetting a device deletes all monitoring and reporting data and removes and re-evaluates all monitors and attributes.

Hirschmann Device Support

In this release, WhatsUp Gold has introduced support for Hirschmann devices in the form of a new subrole. Discovery will automatically detect and configure Hirschmann devices that have a sysObjectID that starts with: '1.3.6.1.4.1.248'. WhatsUp Gold will automatically configure and apply some active and performance monitors for applicable devices with the new subrole upon discovery.

Important: WhatsUp Gold no longer supports TFTP server. If you have a TFTP server instance in use, it will be uninstalled upon upgrade to WhatsUp Gold 2026.

Known Issues

Feature Area Item Description Workaround Applicable Release Version(s) Fixed Release Version
Reporting WUG-19216

In the Certificates report (and other pages that use the shared device picker), changing the device filter may not update the active selection, causing the report to continue using a previously selected device even after choosing All Devices or a different node. As a result, the report can appear empty or fail to show the expected devices until you explicitly select another node and then reselect the desired scope.

 None 26.0 N/A
Log Management WUG-18903

Agent client builds using Go versions higher than 1.16.7 may fail to connect to WhatsUp Gold due to an incorrect flag in the agent certificate.

Existing installations may need to regenerate agent certificates from the Agent General Settings dialog, which will trigger a redeploy of all current agents.

 26.0 N/A
Certificates WUG-19448

Devices discovered and monitored in WhatsUp Gold 25.x do not have their existing certificate data migrated into the new certificate tables after upgrading to 26.0, so certificate information may be visible under Device Properties → Monitors but not in Inventory or Dashboard reports.

To populate certificate data in these reports, you must re-discover affected devices in 26.0 and then start or update certificate monitoring.

 26.0 N/A

Things You Should Know

Important: To monitor a MySQL database, download and install the MySQL .NET Connector on the WhatsUp Gold machine. Please note, the latest version of WhatsUp Gold only supports MySQL .NET Connector version 8.0.21 due to potential compatibility issues. If you are using application monitoring features and/or SQL Query active or performance monitors, you must download and upgrade your connector from version 5.2.5 to 8.0.21. The MySQL .NET Connector can be downloaded here: https://downloads.mysql.com/archives/c-net/.
Important: If Agents were deployed and in use prior to upgrading WhatsUp Gold, they must be redeployed to apply any available fixes or updated functionality. To redeploy agents and fully complete your upgrade of WhatsUp Gold, ensure you are logged in to WhatsUp Gold using an admin account with permissions to deploy WhatsUp Gold Agents. Next, navigate to SETTINGS > WhatsUp Gold Agent > Agent Library from the main menu. Select all existing agents displayed in the library, then click Deploy Agent.
