The new Internet era has arrived bringing a mix of network architectures and constant user demand for higher bandwidth, quality and “security”. As network coverage grows, the degree of network threat has become alarmingly sophisticated. Security flaws have increased awareness of the importance of network security, which has brought new technology and new solutions to the market. Additionally, research has shown more and more computer demand from mid-to-small businesses, which has led to the rise of the new Unified Threat Management (UTM) appliance, bringing with it big headaches for security vendors. While hardware appliances remain popular as a simple means of delivering secure computing, more emphasis is placed on defining an ideal appliance that takes into account the variations in hardware design, different architectures, solutions and processors.
