Cyber Security is a major issue worldwide. A cyber breach can result in the theft of sensitive customer and employee data, intellectual property, identity and cash. Not only is a business disrupted but it is also exposed to liability, litigation and reputational damage. The growth of Cloud Services and of the Internet of Things (IoT) have compounded the security challenges. SMEs cannot afford the enterprise products that are effective in detecting the latest generation of banking and data leakage malware. UK government figures for 2015 show the cost of a security breach to a single SME can be more than £300,000.
