Use "one-way" clipboard
By default the clipboard works both ways. Into the published app/desktop and out of the published desktop.
But you can tweak this.
For XenApp before v7.0: You can make the clipboard READ ONLY for the app. So you can paste INTO the published app/desktop but not copy out of it. This feature has existed since 2009 and is done via Windows registry. (Archived here.)
- Namely:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\Virtual Clipboard\ReadOnly-> DWORD1
- Namely:
For XenApp versions starting newer than v7.0 but older than v7.6: No idea.
For XenApp v7.6 and later: You can FILTER a direction. This is a new XenApp 7.6 feature from 2015. (Archived here.)
- There is a largeish eDocs entry on this. (Archived here.)
Note: I work with Citrix a lot, but I have never tried this feature, so I can't offer hands-on-experience for it.

Don't think so. Open another question for this if you need more input on this. – StackzOfZtuff – 2016-04-06T09:34:56.023
Citrix is probably keeping the local and remote clipboards in sync. This is frequently a desirable feature. See if Citrix's options allow you to disable that. – Neil Smithline – 2016-04-01T15:34:02.393
So that is a security flaw in the remote session as users can paste information from remote to local machine inadvertently and remote session would not know about it? – user1243255 – 2016-04-01T21:03:10.410
I don't know that I'd say it's a flaw. Clipboards are inherently insecure. Once you or something into it, you pretty much lose control. – Neil Smithline – 2016-04-01T22:00:03.470
