Worldwide spending on information security products and services will reach $81.6 billion (€72.9 billion) in 2016, an increase of 7.9% over 2015.
According to the latest forecast from Gartner, consulting and IT outsourcing are currently the largest categories of spending on information security.
Until the end of 2020, the highest growth is expected to come from security testing, IT outsourcing and data loss prevention (DLP).
Preventive security will continue to show strong growth, as many security practitioners continue to have a buying preference for preventive measures. However, solutions such as security information and event management (SIEM) and secure web gateways (SWGs) are evolving to support detection-and-response approaches.
Consequently, Gartner expects the SWG market will maintain its growth of 5 to 10% through 2020 as organisations focus on detection and response.
Detection and response
“Organisations are increasingly focusing on detection and response, because taking a preventive approach has not been successful in blocking malicious attacks,” Gartner senior research analyst, Elizabeth Kim, said. “We strongly advise businesses to balance their spending to include both.”
Kim said that security spending will become increasingly service-driven as organisations continue to face staffing and talent shortages.
Managed detection and response (MDR) is emerging, with demand coming from organisations struggling to deploy, manage and use an effective combination of expertise and tools to detect threats, and then bring their environment back to a known good state.
“This is particularly true for targeted advanced threats and insider threats,” Kim added. “With more MDR providers emerging targeting the mid-market, we foresee these services being an additional driver for security spending for both large and smaller organisations.”
According to Gartner, spending in security markets such as consumer security software, secure email gateways (SEGs) and endpoint protection platforms (EPPs) continues to show constrained growth due to commoditisation.
Spending habits
Other assumptions in the information security market behind Gartner’s latest forecast include that the average selling price for firewalls is expected to increase by at least 2 or 3% year over year until the end of 2018.
“This is driven by the market benefiting from higher demand for high-end equipment among cloud providers and other service providers, due to larger bandwidth needs and an increasing number of devices,” Kim added.
“While vendor competition continues to put pressure on pricing, enterprises, service providers and web-scale organisations are moving toward deploying bigger and more expensive firewalls.”
As a result, the deployment of large firewalls by cloud service providers will remain an important source of revenue growth for vendors.”
By 2018, Kim said 90% of organisations will also implement at least one form of integrated DLP, up from 50% today.
“Organisations have been deploying DLP to address regulatory compliance, intellectual property (IP) protection and data visibility and monitoring,” Kim added.
“Newer solutions that include user entity and behaviour analytics, image analysis, machine learning, and data-matching techniques are being used to augment existing solutions.”
In addition, Kim said Public cloud adoption will impact firewall spending by less than 10% until the end of 2019 but will have an impact after that.
CASB evolution
While software as a service (SaaS) adoption is growing, the effect on firewall spending will be limited for the next three years – SaaS is the first choice for only 16% of CIOs surveyed by Gartner in 2015.
“Transitions also take time, during which vendors of cloud access security brokers (CASBs) will not only continue to evolve to cover more than just SaaS, but also perform similar roles for infrastructure as a service (IaaS) and platform as a service (PaaS),” Kim added.
In addition, firewall vendors will also have to deal with one of their main challenges for the next few years: decrypting Secure Sockets Layer (SSL) at scale.
“Half of midsize and large organisations will add bigger, more advanced inspection-oriented features to their network firewalls by 2019,” Kim added.
“Bandwidth has been increasing, requiring larger-scale, higher-performing and more expensive firewalls. In addition, organisations are looking to firewalls to consolidate other features, such as web filtering and intrusion prevention capabilities.
“Some are enhancing their firewalls with new content inspection features, such as malware sandboxing.”
