Plus it is much easier to gouge corporations and charge tons of money. The amount of money corporations will spend on things is mind boggling.
It's not so much about gouging. The ecosystem of corporate/enterprise is very different than consumers in key areas. Such as reliability, stability, compatibility and support. A small incorrect signature, bad update or machine learning bug can cost corporations millions of dollars. But for consumers, it's no big deal most of the time. For development.. In my experience consumers always get the scraps unless the firm was focused on consumers. Eventually some of the technology filters down to the consumer level, but I don't see the same amount of development man-hours devoted to the consumer stuff.
You can't fault firms that do this. When a single company feeds Trend Micro $12,000 a month in Worry Free Advanced licensing fees, how many consumers have to buy Trend Micro Titanium to match that? Then compound that by thousands of corporations around the world. Then subtract the free/cheap/discounted/promo licenses Trend probably doesn't make any money on.
The real driver here is.. You get John Smith to run Trend at home.. John goes in to work, where he is COO or Director of this or that.. Then IT presents AV migration solutions and he says 'Hey, that Trend stuff is decent, can we go with that?'. I can't tell you how many meetings I have sat in where this happens.
Both Trend and Norton corporate solutions are generally far superior to their consumer offerings. But I think this may apply to other brands as well if you take a look. Not only do they tend to use encrypted communication channels, but they also tend to have more stable releases, better testing, longer beta periods, better support and no bloat.
