I’m a big fan of Planar Systems. They are a very personal company in an 
impersonal business whose product lines target the exhibition market. US based 
with great personal support and their products are world class.

I wrote this a few weeks ago in response to a similar question. It does not 
directly address securing a browser running HTML, but I hope it’s helpful.
