Data Security: Data breaches happen all the time. News reports of hacking and industrial espionage hit the headlines daily and present a serious threat to small and medium sized businesses. On-premise software still presents its own set of security concerns, but be wary of new technologies and vendors who do not have a robust security system in place.Ongoing Business Concerns: Small and medium sized businesses many times have no option but to outsource certain tasks, such as IT.
