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.

Today’s rapidly evolved cyber threats have proved that legacy protection methods are incapable of preventing malicious attempts from attacking enterprise networks. Therefore, it is time for “next-generation firewall” or “NGFW” for short, a term coined by Gartner, to mitigate the advanced cyber attacks and protect enterprise serviceability.

2018 FIFA World Cup, the world’s largest sport event this year, is held in Russia and participated by 32 national teams contesting through a qualifying competition with more than 1.5 billion soccer viewers worldwide. In fact, this is considered the most costly World Cup so far, with latest technological deployments like 5G infrastructures and VR-assisted equipments. However, such high-profile events are attracting potential cyber attacks at the same time. For example, the Winter Olympics in early 2018 was found with an incident that the IP television in the press center was hacked during the opening ceremony.

In today’s business landscape, enterprises are relying more and more on cloud-based web applications to offer 24/7 serviceability, enhance competitiveness and expand user bases. Whether these web applications are deployed on –premises with private cloud settings or in cloud infrastructure with large data center, they have become frequently exposed to cyber criminals and suffered from web service outages caused by advanced cyber attacks, such as DDoS, spear-phishing, and SQL injection. According to Q3, 2016 State of Internet Security released by Akamai, in the Web Application Attack Frequency, SQLi accounted for nearly 50% of observed web attacks.
