Ovum view


The ability to shield companies from distributed denial-of-service (DDoS) attacks is set to be the most sought-after cybersecurity capability through 2021, according to Ovum's just-published market forecast for the enterprise security market. Indeed, network security generally (which includes DDoS) offers the greatest revenue opportunity for the period.

There are many reasons to invest in network security

Our newly issued Software Market Forecasts: Security, 2016‒21 shows DDoS protection, which includes detection and mitigation technologies, enjoying a compound annual growth rate (CAGR) of more than 15% for the period. That makes it the fastest growing segment of a global IT security market already worth $57bn by 2021, outgrowing the market's overall forecast CAGR of 9.4%.

Indeed, the network sector, as well as being the largest part of the market ($19.5bn by 2021), has the most high-growth segments, with network security, including unified threat management (13.44%) and SSL VPN (12.57%), following close behind DDoS.

The reasons for the preeminence of such segments include

  • the unending growth and development of DDoS, with attacks growing in average size as well as becoming varied in type

  • the evolution in networking technology, with trends such as software-defined networks presenting new security challenges

  • the changing nature of work, with ever more employees working remotely for at least part of the time, as well as the continued trend of companies outsourcing some business processes to third parties.

That said, the three segments of identity and access management (IAM) all will enjoy solid CAGR through 2021: authentication at 10.7%, access control at 10.31%, and provisioning at 10.15%. And what Ovum terms security management, which covers everything from patch and vulnerability management through to security incident and event management, will see solid growth throughout the period, coming in with a total value of $11bn in 2021, just behind IAM at $11.1bn.
