VPNs, possibly. I don't know, for sure, how many use them for work, versus those who use them to evade governments. In the latter category it could encompass things as varied as pirating tv shows, to circumventing the Great Firewall of China. But Chinese workers use VPNs for remote work, too. As for Tor, I doubt that anyone is using that for work, but I also doubt that many are really using it for anything illegal. To be sure, there are the Silk Road-type sites, but Tor speeds are not conducive to piracy (and Bit Torrent is highly discouraged on the Tor network).
