The enterprise network security landscape is evolving rapidly as organizations accelerate their shift to the cloud, adopt hybrid work models, and rely on an increasing number of internet-based applications accessed by globally distributed users. At the same time, the attack surface continues to expand, exposing fully digitalized enterprises to new and sophisticated threats. To take advantage of the opportunities in this market, equipment vendors, service providers, and financial institutions need to answer critical business questions, including:

  • Where are the fastest-growing segments in network security, and how quickly are enterprises transitioning from traditional security appliances to cloud-native and AI-driven security solutions
  • How have hybrid work models and post-pandemic enterprise strategies impacted network security architecture and purchasing patterns?
  • Will the $10 B+ firewall market fade, or will it continue its nearly thirty-year march of consistent growth?
  • How is cloud-delivered network security in the form of security service edge (SSE) solutions reshaping the market? What is the market adoption of its four primary functions (cloud access security brokers (CASB), firewall-as-a-service (FWaaS), secure web gateway (SWG), and zero-trust network access (ZTNA)?
  • Why are Web Application Firewalls (WAF) and API security solutions experiencing higher growth compared to traditional firewalls, and how are modern applications shaping this trend?
  • What role are hyperscale cloud service providers playing in reshaping the network security ecosystem, and how are vendors aligning to meet this challenge?
  • Which vendors are leading the shift to platform-centric security architectures, and how are they differentiating through innovation, ecosystem partnerships, and AI integration?

Dell’Oro Group delivers quarterly reports and 5-year forecasts on the Network Security market to answer these and other essential questions.
