Bitlocker Non-Compliance Reporting

As part of the suite of security tools I am writing, this will query the configuration manager SQL database for a list of machines that are not Bitlocker encrypted. There are reports in the configuration manager for this, but not everyone in my organization has access to the configuration manager console, and we wanted a detailed report sent out on a regular basis so that it is in their mailbox with high importance, which is also not available through ConfigMgr. 

This tool was written to include the computer name, model, chassis, drive letter, bitlocker status, last hardware inventory scan, and last logon time. The last hardware scan and last logon time give the admins an idea as to the accuracy of the system being reported. The tool was written so that it can be used with Azure Automation or Orchestrator, and even with a scheduled task if needed. The output is formatted for a clean appearance in an outlook email. 

You can download the script from my GitHub site.

      .SYNOPSIS  
           Bitlocker Encryption Reporting  
        
      .DESCRIPTION  
           This script queries the Configuration Manager SQL database for a list of machines that are not Bitlocker Encrypted. It is limited to non-desktop chassis, which can be changed by modifying the SQL query. The script is designed to output the data so that it can be used with Orchestrator, Azure Automation, or a scheduled task.
