Google has ehnhanced its Desktop Search tool by releasing a new version called Enterprise Edition.
This new version (totally free, exactly like the standard version) is specifically created for corporate usage and it can search on your local machine, on the Internet and also on your Intranet (as you can see on the picture below, it adds a new Intranet tab for searching).
Unfortunately seems that Intranet search is only available if you have a Google Mini or Google Search Appliance, but it's a good news to see that now you have an administrative panel where you can centrally manage user preferences using Microsoft Group Policy settings (for example, you can restrict Google Desktop Search from indexing specific websites that may contain sensitive information or prevent it from indexing a specific file type, such as IM chats) and now you have support for shared workstation environments (now if you have multiple users on the same Windows machine, Google Desktop Search for Enterprise enables you to give users secure search across just the files they have access to on shared workstations).
Will be this tool more secure than the standard version? The time will give us a response...
