Marcus J. Ranum comes up with a nice summary of Gartner on the firewall-wizards mailing-list.

You've got to understand that most of the input into Gartner is from briefings arranged by the marketing departments of companies that are paying them to listen to their briefings. Basically, Garter sits at the apex of the hype food-chain; they consume pure hype and produce little sh&t-pellets of hype that is[sic] as dense as neutronium.
