we really tried to focus this article on newer companies, ones that launched in last year or so or only recently started shipping products (or are about to...).

One thing we are also interested in hearing about are companies, like Vaultus, that spin out of university research labs. We try to cover a lot of that sort of news in our Alpha Doggs blog on network research: http://www.networkworld.com/community/?q=alphadoggs
