Kolodgy disputes the notion that UTM was ever truly considered a "dirty word" among enterprises and said that earlier products simply weren't architected to appeal to administrators of larger IT environments. Like many other IT trends, the UTM concept took something of a beating because it was over-hyped by the media and used by a large number of security companies selling different types of products under the name.
"I never saw it as a dirty word, it was more of a case of some perhaps putting too much into it, some that were too narrow, those were the initial complaints vendors," Kolodgy said. "The initial use cases and deployments were mostly fine; I think any negativity was related more to vendors using the term a lot and misconceptions of what these devices were supposed to entail."
The analyst said that today's UTM vendors, Fortinet and SonicWall in particular, have created UTM devices that should appeal to larger customers because they have the capability to handle more traffic and offer benefits from consolidation among the onboard security applications.
"[Consolidation] is one of the big drivers now, more people than ever are talking about reducing the number of vendors they have and the need for centralized management," Kolodgy said. "As much as the products getting better, those items are driving this renewed interest as much as anything."
