A strategically deployed application delivery controller (ADC) provides not only improved security, visibility and acceleration; it ensures the availability of mission-critical applications. One of the global leaders in ADCs approached Lanner when they were developing their latest product. As a global leader, they were not looking for a standard run-of-the-mill application networking appliance. They were looking for hardware suited for a next generation application delivery controller.

Firewalls started to become a commodity many years ago. One of the US-based companies that saw this trend early is one of Lanner’s customers today. It has taken 8 years, but today they are considered a leading company in universal threat management and next generation firewalls. Together with Lanner they’ve designed three generations of network security product lines and climbed up to their leadership position fueled by their advantages in both cost and technology.

A multi-service gateway (MSG) is a highly integrated device that combines multiple network functions and data communications into one single service, a very budgetary solution targeted at small and medium enterprises (SMEs) and retail setting. The functions of a multi-service gateway include routing, VoIP, and security instructions like VPN, firewall and IPS/IDS. More advanced smart gateways may also be programmed with web filtering, email server, high-volume storage and wireless networking hub.

Application Delivery Controllers (ADC) are networking devices normally deployed in datacenters as part of an application delivery network (AND). Today, due to exponential growth in Internet traffic contributed by cloud-based business applications and services, application delivery controllers are deployed to perform load balancing, DMZ buffering and application flow optimization.

In order to provide access to data on any device at locations such as stadiums, shopping centers and medium-sized branch offices as well as campuses, content providers and telecom companies are required to build their information superhighways on both wired and wireless networks that deliver enterprise-scale capacity, stringent performance and reliability.

WAN optimization, also known as WAN acceleration, is a set of technologies and/or techniques applied to maximize the efficiency of data flow across a wide area network (WAN). In an enterprise WAN, the goal of optimization is to increase the data transfer speed and bandwidth regarding accesses to critical applications and information.

Unified Threat Management, frequently abbreviated as UTM, is a single appliance that specializes in all-inclusive security functions, such as network firewall, intrusion detection/prevention system (IDS/IPS), anti-virus gateway, anti-spam gateway, VPN, content filtering, load balancing, data loss prevention and appliance monitoring.
