By 2020, the information security technology market is estimated to be worth 105 billion U.S. dollars worldwide, while revenues are expected to reach 96 billion U.S. dollars in 2018. Security services represent a major market and are forecast to generate 58 billion U.S. dollars. Security software has increasingly played a valuable role in the global IT security industry, producing revenues of 23.6 billion U.S. dollars in 2016. The largest firms are multi-billion dollar companies, with Symantec and McAfee earning revenues of 3.4 billion U.S. dollars and 1.8 billion U.S. dollars respectively.
Analysts have suggested that security trends are being shaped by new markets, such as big data or the internet of things. One impact of this has been the shift towards managed security services, a result of the difficulty organizations face in deploying and managing the skills and equipment necessary to face new, rapidly evolving threats. Consequently, security appliances have recorded increased revenues, peaking at 3.3 billion U.S. dollars as at Q4 2016 and 3 billion U.S. dollars in Q2 2014. Cisco and Check Point are remarkable security appliance vendors, occupying the largest individual markets shares of 15.3 and 12.8 percent respectively as at 2016. Other industry players are Palo Alto Networks, Fortinet, Huawei, Blue Coat, Intel Security, Juniper and McAfee.
