IntraNET
If you're thinking of the "dark web", you're probably just thinking of a ganger-operated IntraNET with a ton of weird Black ICE that could probably kill you.
IntraNETs are common across strata, from Edgerunners running E-Bulletin Boards[1] to avoid NCPD scans, to Streetscum using them to peddle drugs via digital silk roads and even to Corpzoners running one to avoid the hassle of setting up a Data Fortress.
IntraNETs are cheaper, they connect multiple devices across realspace and, best of all, require little security since they can be accessed remotely only by possessing a physical dongle.
In formal speak, Corpzoners refer to their IntraNET as an EPN (Enterprise Private Network), since the way they are set up makes them more akin to a VPN than anything else.
