You can't think of an enterprise that doesn't want all of its web browsing metadata collected by third parties? Some enterprises are much more security-conscious than that. I have seen protected paper trash bins in a research lab and office buildings with X-ray scanners (mainly for electronic devices, not weapons).

There's already Island browser that competes in this space. Plenty of companies pay for browser control that goes beyond what the normal policies can provide.

Governments come to mind. European ones, especially.
