SASE Market to Hit $17B by 2029 with 17% YoY Growth

The Secure Access Service Edge (SASE) market is experiencing explosive growth, with global revenues increasing 17% year-over-year in Q1 2025 to reach $2.6 billion, according to Dell'Oro Group analysis. The market is projected to reach $17 billion by 2029, with some forecasts suggesting $16-25 billion by 2027-2028.

This growth is driven by enterprises shifting from traditional VPNs to zero-trust architectures, particularly as distributed work environments become the norm. SASE integrates SD-WAN with security services like Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), and Zero Trust Network Access (ZTNA), providing unified, cloud-native security and networking.

AI is playing an increasingly central role in SASE evolution, enhancing network performance, threat detection, and automation. AI capabilities now enable real-time threat responses, predictive analytics for bandwidth requirements, and optimized data processing in cloud environments. Solutions like VeloRAIN are using AI for application identification and dynamic slicing, with GenAI becoming mainstream for management functions.

Zero-trust principles are now considered "table stakes" in SASE strategies, with organizations implementing incremental frameworks focused on identity-based access for sensitive applications. Industry experts recommend prioritizing unified SASE platforms that consolidate multiple security functions, reducing complexity and improving visibility.

Notable deployments include enterprises using HPE Aruba Networking SD-WAN and partnerships like Adaptiv Networks with National Wireless, integrating SD-WAN and SASE for enhanced connectivity and cybersecurity in small and medium-sized enterprises.
