Hi ledj, The open edition is the OS base that is open source. This explains the features. [URL]   VLT is not mentioned, so it needs an enterprise license. Let us know if you have any additional questions.
Hi Do I need an Enterprise license to use vlt on OS10? Or will open edition work with vlt? Just a little confused on what an Enterprise license actually does.  
Is a OS10 license necessary for vlt?
