This is an entirely new category and it has become one of the most important areas of next-generation network and data protection. Over the course of the past year or so we have been watching this category. When a new approach to security appears on the horizon we always are interested, if a bit skeptical. Over the years there have been a lot of "promising" approaches to security that claim to be game changers. So it should come as no surprise that those of us in this business might become a bit jaded by the hype that tends to surround these pronouncements. Having said that, it certainly appears to us that this emerging category is the real deal.
