Symantec Endpoint Encryption solutions use a standard MSI package to install our software. Subsequent updates will also use the MSI package to install updates. This Feature Request is to include the ability to have the Symantec Endpoint Encryption clients use a "patching" model where individual packages within the software could be applied such that deployment is not needed with the full-blown MSI package.
This request is currently being considered for a future release of the Software. Please check back on this request for future updates. If you would like to follow-up with Symantec directly, please log a new ticket and reference the Jira ID below.
