Tenable Patch Management 2025 Release Notes

Significantly Improved Installation Experience

The server and client installation process has been updated and simplified, with additional checks run to ensure functionality. The server installer includes new checks for cloud services connectivity. The client installer now creates the appropriate firewall rules on Linux and MacOS client operating systems. The client installer also performs several post-setup checks to ensure functionality.

Introduction of Client Validation Tool

A new client validation tool has been included to perform post-installation connectivity checks.

This tool verifies that the client can successfully connect to both local and cloud services. This experience is available cross-platform, both in the windows installer and the adaptivactl. The tool can also be executed by the user on an ad-hoc basis whenever necessary, especially for troubleshooting purposes. With these changes, administrators will always be certain that new client deployments are successful.

• All clients are now targeted by default when a Tenable Patch Management license is added.

• Additional updates made to improve the navigability of Business Units, the creation of Patching Strategies, and improved row selection in tables.
