As cyberattacks grow more sophisticated and AI-powered threats escalate, enterprises are under pressure to evolve beyond traditional perimeter-based network security. Many are turning to Secure Access Service Edge (SASE), a cloud-native framework that converges network and security functions to protect distributed workforces, optimize network performance, and simplify management across multiple tools.
SASE platforms typically include SD-WAN, secure web gateway (SWG), firewall as a service (FWaaS), cloud access security broker (CASB), and zero-trust network access (ZTNA). They can also encompass a growing list of additional features such as browser isolation, sandboxing and data loss prevention (DLP).
The overall SASE market is projected to climb from $15 billion in 2025 to $28.5 billion by 2028, according to Gartner. Deployments are split between single-vendor SASE platforms and dual-vendor approaches, the research firm says.
