The Dell’Oro Group's latest report indicates that global revenue from network security reached $6.4 billion in the second quarter of 2025, reflecting an 8 percent year-over-year growth. This increase is attributed to significant gains in Security Service Edge (SSE) and Application Delivery Controllers (ADC), as organizations adopt AI-focused protection strategies.

Market Growth Overview

The report highlights that Security Services Edge (SSE) experienced a 19 percent increase and Application Delivery Controller (ADC) surged by 24 percent, both notably outpacing the overall market growth. Moreover, virtual firewalls rose by 27 percent, while physical appliance revenues contracted by 5 percent, suggesting a shift towards software and cloud-based solutions in network security.

Revenue Projections

Forecasts indicate that revenue from cloud- and software-delivered security solutions is expected to grow by 20 percent in 2025, whereas hardware appliance revenues are predicted to decline by 2 percent. The entire Network Security market is anticipated to exceed $26 billion in 2025, bolstered by zero-trust mandates and expanding cloud workloads.

Product Performance Insights

In terms of specific products, virtual ADC revenues increased dramatically by 49 percent year-over-year, with Software-as-a-Service (SaaS) Web Application Firewall (WAF) revenues growing by 21 percent. Virtual and SaaS-based solutions currently account for 78 percent of new market spending.
