Significantly Improved Installation Experience

The server and client installation process has been updated and simplified, with additional checks run to ensure functionality.

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.
