Information security - Statistics & Facts

Information security refers to the practice of managing access to information, whether that is securing information from unauthorized access, or verifying the identity of those who claim to have authority to access information. In the consumer context, information security may be limited to the use of passwords to control access to computer hardware, or the use of firewalls and anti-virus software to protect desktop computers and other electronic consumer devices from harmful or malicious intrusion. At the other end of the spectrum, enterprise information security is a complex undertaking, covering computers, servers, routers, telecommunications equipment, and other electronic systems, relying on software, hardware, and information management policies to secure corporate data.

By 2022, the information security technology market is estimated to be worth 133.7 billion U.S. dollars worldwide, while revenues are expected to reach 124 billion U.S. dollars in 2019. Security services represent a major market and are forecast to generate 64 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 in the industry are multi-billion dollar companies. Symantec, one of the biggest companies in the industry, earned revenues of 4.8 billion U.S. dollars in 2018.

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, from 3.1 billion U.S. dollars in the second quarter of 2017 to 3.6 billion U.S. dollars in the second quarter of 2018. Cisco and Palo Alto Networks are noteworthy security appliance vendors, occupying individual market shares of 15.5 and 12.8 percent respectively as at 2018. Other industry players are Check Point, Fortinet, and Symantec.
