Yes, but not on SIPRNet, which was my point. Even inside a SCIF “SIPRNet” is too low a classification network for this discussion, and SIPRNet can be accessed outside of SCIFs in spaces cleared for up to Secret.

Well, ish… SCIFs are used for the collection, dissemination, and storage of Top Secret/SCI material. Secret Internet Protocol Router Network (SIPRNet) is only cleared for up to secret level material. There are higher classification networks they should have been using instead.
