I can't think of a single enterprise who I have worked with or know who'd pay for this when there's Chrome or Edge available.
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.

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).
