Growth in worldwide cloud-based security services will remain strong, reaching $5.9 billion in 2017, up 21 percent from 2016, according to Gartner, Inc. Overall growth in the cloud-based security services market is above that of the total information security market. Gartner estimates the cloud-based security services market will reach close to $9 billion by 2020 (see Table 1).
Gartner analysts discussed cloud security trends during the Gartner Security & Risk Management Summit taking place in National Harbor, Maryland through Thursday.
SIEM, IAM and emerging technologies are the fastest growing cloud-based security services segments.
"Email security, web security and identity and access management (IAM) remain organizations' top-three cloud priorities," said Ruggero Contu, research director at Gartner. Mainstream services that address these priorities, including security information and event management (SIEM) and IAM, and emerging services offer the most significant growth potential. Emerging offerings are among the fastest-growing segments and include threat intelligence enablement, cloud-based malware sandboxes, cloud-based data encryption, endpoint protection management, threat intelligence and web application firewalls (WAFs).

Increasing security threats, operational and cost benefits and staffing pressure drive market growth.
Small and midsize businesses (SMBs) are driving growth as they are becoming increasingly aware of security threats. They are also seeing that cloud deployments provide opportunities to reduce costs, especially for powering and cooling hardware-based security equipment and data center floor space.
"The cloud medium is a natural fit for the needs of SMBs. Its ease of deployment and management, pay-as-you-consume pricing and simplified features make this delivery model attractive for organizations that lack staffing resources," said Mr. Contu.
The enterprise sector is also driving growth as they realize the operational benefits derived from a cloud-based security delivery model.
"Cloud-based delivery models will remain a popular choice for security practices, with deployment expanding further to controls, such as cloud-based sandboxing and WAFs," said Mr. Contu. According to a global survey conducted by Gartner at the beginning of 2016, public cloud will be the prime delivery model for more than 60 percent of security applications by the end of 2017.
"The ability to leverage security controls that are delivered, updated and managed through the cloud — and therefore require less time-consuming and costly implementations and maintenance activities — is of significant value to enterprises," said Mr. Contu.
Cloud-based security services market growth presents opportunities and challenges for providers.
"On the one hand, new greenfield demand arising from emerging requirements from SMBs is driving growth. On the other hand, new competitive dynamics and alternative pricing practices threaten traditional business models," said Mr. Contu. Providers need to adapt to the shift from an on-premises to a cloud-delivery business model. "Overall, one of the main focus areas for providers relates to the shift from owning and selling a product, to selling and supporting ongoing service delivery."
